Abstract:
Stöber’s method and two-component systems (considering alkoxysilanes) were used to develop tech-niques for the synthesis of spherical silica particles with ≡Si(CH2)3NH2 groups in the surface layer. The in-fluence of synthesis conditions on the size of synthesized spherical particles and concentration of functional groups were studied. DRIFT, SEM and acid–base titration were used to identify the composition of the sur-face layers and morphology of the obtained silica particles. There was analyzed the influence of the order entry components, the stirring time, the drying mode, the ratio of react

Abstract:
Magnetic resonance imaging is one of the most widely used diagnostic techniques in the clinic as it affords many of the attributes sought from a non-invasive imaging modality. The main limitation of MRI is its inherent insensitivity, and as a result only large-scale abnormalities can be detected from a scan. With an increasing demand for earlier cancer diagnosis there has been a move towards imaging the molecular biomarkers that are present from the beginning of the disease process.

Abstract:
Nanoparticles have been extensively explored for biomedical applications primarily due to their nanoscale dimensions that allow them to cross biological membranes and to interact with cells and cellular components. The use of well defined inorganic nanoparticles lacks the necessary functionality to be useful in a wide range of applications, especially those in biology and medicine. As such, in order to overcome these limitations, surface modifications of nanoparticles allows tuning of the interfacial properties such as hydrophilicity, binding and adsorption of molecules and proteins, and cell

Abstract:
ROS (Reactive Oxygen Species), such as H2O2, HO● and O2-●, are naturally produced by the metabolism of living beings. However, they can appear in large quantities in the case of certain diseases (Alzheimer's, Parkinson's, sclerosis, cancer). Overproduction of ROS leads to higher cell mortality. Some microorganisms have an Mn-based enzyme capable of catalyzing the disproportionation reaction of H2O2 into O2 and H2O. Several molecules have been synthesized to reproduce this process, however very few of them are active in aqueous environment. R

碩士<br>國立臺灣科技大學<br>化學工程系<br>95<br>The first part of this work is to prepare and characterize transparent nanosized silica hydrosol using tetraethylorthosilicate ( TEOS ) as the monomer, double-deionized water as the solvent, and a small amount of surfactant SDS to reduce the interfacial tension of the O/W phase. After hydrolysis of TEOS followed by a condensation reaction in aqueous solution, ammonium hydroxide solution is added to terminate the sol-gel reaction. And the nanosized silica hydrosol is obtained. In this work, we also study the influence of reaction time, reaction temperature, and

博士<br>國立臺灣大學<br>化學研究所<br>101<br>Hybrid nanoparticles constructed from organic and inorganic components have been attracting increasing interest in both industry and academia due to its structural diversity and compositional flexibility. Among the various hybrids, silica is believed to be one of the most attractive candidates because their physicochemical stability, biocompatibility, low cytotoxicity and easy functionality. In this study, a variety of highly promising silica nanomaterials were designed and synthesized using a conventional sol–gel pathway. The following descriptions summarize th

Dissertação de Mestrado Integrado em Engenharia Biomédica apresentada à Faculdade de Ciências e Tecnologia<br>Introdução: Embora os hidrogéis possam ser aplicados na imitação do ambiente da matriz extracellular, geralmente fornecem fracas propriedades mecânicas, o que pode ser limitante na sua aplicação biomédica. Nanopartículas de sílica Mesoporosas (MSN) têm capturado a atenção em diversos campos de engenharia de tecidos devido a suas características. Aqui, investigamos a utilização de MSNs como agente reticulador entre as cadeias PEG, de modo a criar um hidrogel com proprie
