Resumo: Hidrogéis e filmes de fibroína de seda foram preparados e caracterizados com o objetivo de avaliar sua potencial aplicação no campo de biomateriais. Hidrogéis foram obtidos durante a etapa de diálise da solução de fibroína de seda e suas propriedades físicas, químicas, citotoxicidade e potencial de calcificação in vitro foram determinados. Esses materiais apresentaram estrutura tridimensional porosa com resistência mecânica à compressão relativamente alta e grande potencial de calcificar in vitro, sendo possíveis candidatos à aplicação na área de regeneração óssea. Filmes de fibroína de seda com quitosana foram preparados utilizando-se a técnica "Layer-by-Layer". Com esta técnica, foi possível depositar filmes anisotrópicos, com fibras alinhadas na superfície de substratos de silício. Como os biopolímeros em estudo são conhecidamente biocompatíveis, o alinhamento de fibras na superfície do substrato poderia ser explorado como um meio de guiar a adesão e proliferação celular ou ainda agregar resistência mecânica a outros filmes poliméricos. Filmes de fibroína de seda foram também empregados para recobrir pericárdio bovino utilizado na fabricação de válvulas cardíacas. Amostras recobertas com fibroína de seda foram avaliadas quanto à sua propensão à calcificação in vitro e os filmes foram testados quanto a sua citotoxicidade e potencial de adesão e crescimento de células endoteliais. Os resultados indicaram que filmes de fibroína de seda não apresentam citotoxicidade, são compatíveis com células endoteliais e não induzem a calcificação do pericárdio bovino recoberto durante os testes in vitro. Assim, o recobrimento com fibroína de seda pode ser uma alternativa de tratamento do pericárdio bovino para funcionalização da sua superfície. Dos resultados apresentados, concluiu-se que tanto hidrogéis como filmes derivados de fibroína de seda podem ser aplicados no campo de biomateriais, sejam como matrizes para reconstituição óssea, ou filmes para recobrimento e funcionalização da superfície de materiais.
Abstract: Silk fibroin hydrogels and films were prepared and characterized in order to investigate their potential application in the biomaterials field. The hydrogels were obtained during the dialysis step and their physical and chemical characteristics, cell toxicity and compatibility and potential to calcify in vitro were investigated. Those materials presented a porous tridimensional structure, mechanical strength and ability to deposit calcium phosphate crystals during in vitro calcification tests; therefore, silk fibroin hydrogels can probably be used in the bone regeneration field. Silk fibroin films were obtained by using the Layer-by-Layer technique. Bidirectional alignment of silk fibroin fibers was designed by adjusting the substrate position during the dipping process. A potential application to films with alignment of fibers is to guide cell adhesion and proliferation, since the biopolymers used to build the films are known as biocompatible materials. Silk fibroin films were also used to coat bovine pericardium used to fabricate cardiac valves. The coated samples were characterized by in vitro calcification tests and biocompatibility of silk fibroin films was evaluated by citotoxicity tests and their ability to adhere and grow of endothelial cells. The results showed that silk fibroin films are biocompatible and do not induce calcification during in vitro calcification tests, being suitable to coatand functionalize bovine pericardium surface. From the presented results, it can be concluded that silk fibroin hydrogels and films are suitable materials to be explored in the biomaterials field, for bone regeneration or biomaterials surface coating.

A pesquisa em materiais naturais aumentou notavelmente nos últimos anos devido à oportunidade de combinar biocompatibilidade com propriedades físicas, mecânicas e químicas excepcionais, o que seria árduo para obter seguindo uma rota sintética. Entre estes polímeros naturais, a fibroína de seda é atraente por sua transparência óptica, excelente robustez mecânica e compatibilidade com sistemas vivos, com a formação de produtos de degradação não inflamatória. Neste estudo, fomos capazes de formar hidrogéis translucidos a partir de fibras de seda crua em diferentes concentrações e usamos como matriz para incorporar uma molécula fotossensível : sódio (4,4 ', 4' '- (20- (4- (3-carboxipropanamido ) Fenil) porfirina-5,10,15-triil) tribenzenossulfonato - para uso futuro na terapia fotodinâmica. Os hidrogéis obtidos foram caracterizados por diferentes técnicas de reologia e análise de espectrofotometria para estudar os fatores envolvidos na formação do hidrogel e para obter informações sobre propriedades da fibroína da seda (SF) após a adição da molécula de porfirina na matriz. O conjunto de resultados obtidos mostrou que os hidrogéis SF têm um comportamento de desbaste de cisalhamento, onde a viscosidade do gel diminui com o aumento da taxa de cisalhamento e que pode ser classificado como materiais tixotrópicos, o que significa que a estrutura do material precisa de tempo para se recuperar após a deformação de cisalhamento da experiência. Além disso, observamos que a estrutura secundária da fibroína não é afetado pela adição de porfirina em qualquer concentração, foi confirmado pelo sinal negativo de Cotom em torno de 220 nm nos espectros de dicroísmo circular. As nanofibras de fibroína porfirina híbridas foram capazes de gerar oxigênio singlete após a gelificação, e provamos que os hidrogéis de fibroína de seda são uma excelente matriz para encapsular outras moléculas para aplicação em terapia fotodinâmica e terapia fototérmica, levando à formação de nanoestruturas de péptido auto-montadas com efeitos fototerapêuticos controláveis.
The research in to natural materials has notably increased in recent years due to the opportunity of combining biocompatibility with exceptional physical, mechanical, and chemical properties, which would be arduous to obtain following a synthetic route. Among these natural polymers, silk fibroin is attractive because of its optical transparency, outstanding mechanical robustness and compatibility with living systems, with the formation of non-inflammatory degradation products. In this study, we were capable to form translucid hydrogels from raw silk fibers at different concentrations and used them as matrix to incorporate a photosensitive molecule - sodium (4,4',4''-(20-(4-(3- carboxypropanamido) phenyl) porphyrin-5,10,15-triyl) tribenzenesulfonate - for future use in photodynamic therapy. The obtained hydrogels were characterized by different rheology techniques and spectrophotometry analysis to study the factors that are involved in the formation of the hydrogel, and to have information about silk fibroin (SF) properties after adding the porphyrin molecule to the matrix. The set of obtained results showed that the SF hydrogels have a shear thinning behavior, where the viscosity of the gel decrease whit the increase of the shear rate, and that it can be classified as thixotropic materials. This mean that the structure of the material needs time to recover after experience shear deformation. Also, we observed that the secondary structure of the fibroin is not affected by the addition of porphyrin in any concentration, it was confirmed by the negative Cotton signal around 220 nm in the circular dichroism spectra. The hybrid porphyrin-fibroin nanofibers were capable to generate singlet oxygen after gelification, and we proved that silk fibroin hydrogels are an excellent matrix to encapsulate other molecules to application in photodynamic therapy and photothermal therapy, leading to the formation of selfassembled peptide nanostructures with controllable phototherapeutic effects.

Resumo: A fibroína de seda tem sido amplamente explorada para aplicações biomédicas, devido à sua biocompatibilidade, biodegradabilidade e mínima reação inframatória. A esterilização é uma etapa fundamental no processamento de biomateriais, e não deve alterar de forma negativa as propriedades funcionais dos dispositivos médicos. Estudos recentes verificaram que a fibroína pode ser utilizada como suporte para mimetizar a biomineralização, promovendo o crescimento de cristais de hidroxiapatita. O objetivo deste trabalho foi analisar a influência de diferentes métodos de esterilização nas características físicas, mecânicas e biológicas de membranas densas e porosas de fibroína de seda, e também estudar a possibilidade de aplicação de membranas de fibroína como biomaterial, pelo estudo da calcificação in vitro. Membranas densas e porosas de fibroína foram esterilizadas por radiação ultravioleta, etanol 70%, autoclave, óxido de etileno e radiação gama, e foram analisadas por MEV, FTIR-ATR, DRX, testes mecânicos e de citotoxicidade indireta. Para os ensaios de calcificação in vitro, as membranas de fibroína foram imersas em SBF por sete dias, e caracterizadas por MEV e EDX. Os resultados de esterilização mostraram que nenhum método ocasionou degradação das membranas ou a formação de produtos citotóxicos. Os métodos que utilizaram solvente orgânico, e aumento de umidade e/ou temperatura (etanol 70%, autoclave e óxido de etileno) tornaram as membranas densas mais cristalinas, e as membranas porosas mais estáveis, o que pode ser aproveitado quando se deseja que as membranas apresentem uma degradação in vivo mais lenta, dependendo da aplicação. Os resultados obtidos de calcificação in vitro indicaram que a fibroína pode induzir a calcificação, pela formação de depósitos de fosfato de cálcio com relações de Ca/P similares à da hidroxiapatita e seus precursores. A membrana porosa apresentou maior tendência à calcificação, quando comparada com a membrana densa, devido à sua rugosidade e porosidade, podendo desta forma ser considerada para aplicação em regeneração óssea.
Abstract: Silk fibroin has been widely explored for many biomedical applications, due to its biocompatibility, biodegradability and minimal inflammatory reactions. Sterilization is a fundamental step in biomaterials processing, and it must not alter in a negative way the functionality of medical devices. On the applicability of fibroin as a biomaterial, recent studies verified that fibroin can be used as a scaffold for mimicking biomineralization, promoting the growing of hydroxyapatite crystals. The aim of this study was to analyze the influence of different sterilization methods on physical, mechanical and biological characteristics of dense and porous silk fibroin membranes, and also to study the application of the fibroin membranes as biomaterials, through in vitro calcification studies. Dense and porous fibroin membranes were sterilized by ultraviolet radiation, 70% ethanol, autoclave, ethylene oxide and gamma radiation, and were analyzed by SEM, FTIR-ATR, XRD, mechanical and cytotoxicity tests. For in vitro calcification experiments, the fibroin membranes were soaked in SBF for seven days, and characterized by SEM and EDS. The results for sterilization indicated that none of the methods caused degradation or formation of cytotoxic substances. The methods that used organic solvent, and increase of humidity and/or temperature (70% ethanol, autoclave and ethylene oxide) increased the crystallinity of the dense membranes, and stabilized the porous membranes, characteristics that may be utilized when a slow in vivo degradation is desired, depending on the application. The calcification experiments indicated that silk fibroin may induce calcification, by forming calcium phosphate deposits with a Ca/P ratio similar to that of hydroxyapatite and its precursors. Porous membranes presented higher tendency to calcify, when compared to dense membranes, due to its surface roughness and high porosity, indicating that porous silk fibroin membranes may be considered for application in bone regeneration.

Full textCalcification occurs by the formation of calcium deposits in different matrices involving mechanical factors, chemical and biological. Some composites, polymers, and proteins are used in forming matrices to promote higher efficiency in the process of mineralization. It is estimated that the silk fibroin also present for this purpose. The fibroin is a fibrous protein extracted from silkworm cocoon silkworm (Bombyx mori), which can be processed as film, membrane, sponge, powder, gel and applied in bone and cartilage, vascular grafts, nerve repair and corneal as a delivery system for drugs, sutures, ligaments, skins, tendons and substrate for cell culture. In this work was the preparation of microparticles of silk fibroin by two different procedures, sputter under N² and in other sputter Na2HPO4 and calcification process was performed by immersion of alternating buffered solutions of calcium and phosphate. The characterizations were performed Absorption Spectroscopy Infrared (FT-IR), Thermogravimetric Analysis (TGA), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS) and Differential Scanning Calorimetry (DSC). The results showed that the calcification of fibroin microparticles occurs by the two methodologies. The calcified fibroin microparticles showed no thermal transition temperature to 120°C, enabling autoclaving of the microparticles dry

Full textThe silk fibroin is a protein synthesized by Bombyx mori species, popularly known as silkworm silk. The Bombyx mori cocoon is composed of fibroin fibers and the sericin protein, which is responsible for joining the fibroin yarns. The fibroin is a quite versatile natural polymer and can be processed to form materials such as films, microspheres and hydrogels. Hydrogels are three-dimensional networks formed by macromolecules and capable of absorbing large quantities of water without losing their structural integrity. Due to biocompatibility, ability to mimic biological tissues, high water content and good diffusion properties of oxygen and nutrients, hydrogels are widely used in biomedical research. The fibroin is biodegradable, thermally stable, highly crystalline, flexible and tensile resistant. Besides, it is insoluble in water and in most organic solvents. The fibroin from Frison Extra and Meada 21 Denier silks was separated from the sericin by the degumming process, whereby the silk fibers were immersed in alkaline solutions and subjected to heating with subsequent dissolution and removal of sericin. Fibroin yarns were dispersed in various solutions: CaCl2:H2O; LiCl:H2O; and LiCl:EtOH:H2O. It was observed that according to the fibroin type and solvent solution used the time to achieve dispersion varied. Texture and rheology were determined for every sample after dispersion. All non-degummed samples had shown increased firmness and elastic module G\'. It was observed that the samples presented a wide behavior range, some that contained sericin or ethanol presented Newtonian behavior. Subsequently the samples were dialyzed to obtain the hydrogels and lyophilized. All samples (with exception of two) have formed hydrogels in a 24 hours period. The lyophilized hydrogels were analyzed by thermogravimetry, diffractometry, spectrophotometry and microscopy. All silk fibroin hydrogels presented high thermic resistance with β-sheet predominance. Morphologically, all hydrogels obtained from LiCl:EtOH:H2O and CaCl2:EtOH:H2O solutions had shown entangled aspect wile hydrogels from LiCl:H2O solutions had shown lamellar structures.

Full textSilk fibroin (SF) is a structural protein found in Bombyx mori cocoons and has properties that are potentially applicable in photonics. This biocompatible matrix is an interesting substrate for different ions or molecules. Furthermore, its variable refractive index allows for photons to be guided in this material enabling their use as biocompatible and resorbable waveguides, which can be used to provide optical energy for various applications, e. g., therapy or imaging into living tissue. Its suitability in optical systems is mainly due to its properties such as: being mechanically robust, presenting very smooth surfaces, highly transparent (> 95%) throughout the visible region of the spectrum and being moldable. In addition, there is an extra feature: the possibility of biochemical functionalization, which may confer greater versatility to these devices. On the other hand, rare earth ions (RE) play a widely known role in the field of photonics. However, there is no studies involving the production of light in doped SF with RE ions and the combination of the mechanical and optical properties of this matrix with the multifunctionality of these ions can be a way to produce new photonic devices. Thus, the aim of the present work was to study the SF matrix structure in the presence of different RE ions (Eu3+ and Tb3+) as well as the interaction between the amino acids from the matrix and these RE ions. The results presented in this manuscript have characterized the RE-SF interactions and supported the mechanisms of energy transfer for excitation of different RE ions in this matrix being important for future applications in photonics

A fibroína da seda extraída dos casulos do bicho-da-sêda é um co-polímero particularmente atraente para aplicações em dispositivos fotônicos e opticoeletrônicos devido a sua transparência óptica, biocompatibilidade e propriedades mecânicas. Esta tese apresenta a obtenção de suspensões e filmes iridescentes-luminescentes de fibroína contendo nanopartículas luminescentes de carbono (“carbon dots”) obtidos a partir de carvão vegetal. As nanopartículas luminescentes de carbono apresentam biocompatibilidade, baixa toxicidade, propriedades de fotoluminescência interessantes e possibilidade de modificação da superfície. Redes de difração foram produzidas nestes filmes utilizando como molde um DVD comercial. Os materiais obtidos foram caracterizados por um conjunto de técnicas de análise: Microscopia de Força Atômica (AFM), Microscopia Eletrônica de Varredura (MEV), Microscopia Eletrônica de Transmissão (MET), Espectroscopia de absorção na região do UVVis, Espectrofotometria de absorção molecular na região do infravermelho com transformada de Fourier (FTIR) e Luminescência. Medidas de luminescência mostram que os carbon dots emitem múltiplas cores entre toda a região do visível. Planos cristalinos foram observados nas imagens de MET das nanopartículas, no qual foram asssociadas a estrutura do grafite. Pela análise de UV-Vis dos carbon dots observou-se que a absorção óptica decai gradualmente à medida em que ocorre deslocamento para o vermelho e para os filmes de fibroína observou-se um ombro referente a transição eletrônica da tirosina (aminoácido de sua composição). A partir dos espectros de FTIR observou-se que não houve mudança na estrutura da fibroína após a adição dos carbon dots. As imagens de AFM e MEV comprovam a presença dos micropadrões periódicos na superfície dos filmes. Os resultados mostraram que os filmes de fibroína contendo carbono dots tem um grande potencial para a biomedicina, principalmente devido os seus parâmetros de luminescência se extenderem em toda a região do visível e por apresentar uma matriz sustentável, com excelentes propriedades ópticas e mecânicas.
Silk fibroin extracted from silkworm cocoons is a particularly attractive copolymer for applications in photonics and optoelectronics devices due its optical transparency, biocompatibility and high mechanical strength. This thesis presents the preparation of suspensions and iridescent-luminescent films of silk fibroin containing luminescent carbon nanoparticles (carbon dots) obtained from vegetal coal. Luminescent carbon nanoparticles present high biocompatibility, low toxicity, interesting photoluminescence properties and possibility of surface modification. Diffraction gratings were produced in these films using a commercial DVD as a template. The materials obtained were characterized by a set of analysis techniques: Atomic-Force Microscopy (AFM), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), UV-Visible Spectroscopy, Fourier transform infrared spectroscopy (FTIR), and Luminescence. Luminescence measurements show that carbon dots emit light at the entire visible region. Crystalline planes were observed in the TEM images of the nanoparticles, where upon the graphite structure was associated. By analyzing the UV-Vis spectra of the carbon dots it was observed that the optical absorption gradually decreases as the red shift occurs. In the UV-Vis spectra of the silk fibroin films it was observed a shoulder referring to the electronic transition of the tyrosine (amino acid of its composition). From the FTIR spectra it was observed that there was no change in the silk fibroin structure after addition of the carbon dots. The AFM and SEM images confirm the presence of the periodic micro-patterns on the surface of the films. The results showed that the silk fibroin films containing carbon dots have a great potential for biomedicine, mainly due to its luminescence parameters extending throughout the visible region and due to a sustainable platform with excellent optical and mechanical properties.
