Resumen
Cancer is a disease that continues to greatly impact our society. Developing new and more personalized treatment options is crucial to decreasing the cancer burden. In this study, we combined magnetic polysaccharide microparticles with a Pluronic thermoresponsive hydrogel to develop a multifunctional, injectable drug delivery system (DDS) for magnetic hyperthermia applications. Gellan gum and alginate microparticles were loaded with superparamagnetic iron oxide nanoparticles (SPIONs) with and without coating. The magnetic microparticles’ registered temperature increases up to 4 °C upon the app

Resumen
Background: This study aimed to synthesise and characterise iron oxide microparticles (IOMPs) using Ixora coccinea flower extracts and evaluate their antioxidant, anti-inflammatory, cytotoxic, and antidiabetic activities. Methodology: IOMPs were synthesised using Ixora coccinea flower extract and characterised using XRD, UV-Vis, EDAX APEX, and SEM. Bioactivity evaluations included anti-inflammatory and antioxidant activities via egg albumin, BSA, and DPPH assays; cytotoxicity through Brine Shrimp Lethality and zebrafish embryonic toxicity assays at 5, 10, 20, 40, and 80 μg/ml; and antidiabetic

Resumen
The removal of selenium from superficial and waste water is a worldwide problem. The maximum limit according to the World Health Organization (WHO) for the selenium in the water is set at a concentration of 10 μg/L. Carbon based adsorbents have attracted much attention and recently demonstrated promising performance in removal of selenium. In this work, several materials (iron oxide based microparticles and graphene oxides materials) and their composites were prepared to remove Se(IV) from water. The graphene oxides were prepared according to the simplified Hummer’s method. In addition, the ef

This study aimed to investigate the cytotoxicity and antifungal properties of Sm(NO3)3.6H2O salt, chitosan/Sm complex, iron oxide (Fe3O4 NPs), and iron-oxide modified chitosan/Sm/ranitidine microparticles. The microparticles of iron-oxide modified chitosan/Sm/ranitidine composites were synthesized from various masses of Sm(NO3)3.6H2O (250-350 mg), chitosan (2,000-2,500 mg), and (5-25 mg) through the microwave-assisted evaporation method.

Resumen
This article presents research on biodegradable stretch sensors produced using biological material. This sensor uses a piezoresistive effect to indicate stretch, which can be used for force measurement. In this work, an attempt was made to develop the composition of a sensitive material and to design a sensor. The biodegradable base was made from a κ-carrageenan compound mixed with Fe2O3 microparticles and glycerol. The influence of the weight fraction and iron oxide microparticles on the tensile strength and Young’s modulus was experimentally investigated. Tensile test specimens consisted of

In this study we compared the ability of conventional and field-emission scanning-electron-microscopy (FESEM) and energy-dispersive analysis of X-rays (EDX) to visualise and map inorganic nano and microparticles in Southern pine (Pinus sp.) treated with an aqueous dispersion of micronised copper-carbonate and iron oxide. Conventional SEM-EDX was able to detect areas of the wood microstructure that contained higher concentrations of copper and iron, but EDX maps were affected by drift and specimens suffered beam damage.

One approach that has demonstrated success in the field of molecular imaging utilizes microparticles of iron oxide (MPIO) conjugated to specific antibodies and/or peptides to provide contrast effects on MRI in relation to the molecular expression of a specified target. The experimental aims of this thesis were 1) to investigate the ability of VCAM-1 and P-selectin targeted MPIO to detect the expression of VCAM-1 and P-selectin on the activated endothelium in-vitro and in-vivo in mouse models of renal and cerebral ischemia reperfusion injury, and 2) develop a novel contrast agent for imaging αv

Resumen
De nouvelles études suggèrent que l'accident vasculaire cérébral ischémique est fréquemment associé à la formation de microthrombi dans la microcirculation corticale. Ces microthrombi sont associés à une augmentation de la taille de la lésion, à un déclin cognitif et à la démence. Il est difficile de prendre en charge ces microthrombi car les méthodes d'imagerie actuelles ne permettent pas de les détecter. Pour y remédier, un nouvel agent théranostique a été développé, les IO@PDA@tPA, combinant des microparticules d'oxyde de fer (IO) enrobées de polydopamine (PDA) et conjuguées avec l’activate

Resumen
Abstract In this study, we design, fabricate and characterize a novel unimorph-like structure in which a shape memory polymer (SMP) is actuated using a magneto-active elastomer (MAE), resulting in contactless and large deformation shape change. The constituent materials are: a two-part elastomer, iron oxide microparticles, and a rapid cure epoxy. Combining the elastomer with the iron oxide particles results in an MAE actuator, such that application of an external magnetic field induces dipoles in the iron oxide particles, resulting in the actuation of the MAE.
