Transition metals supported on carbons play an important role in catalysis and energy storage. By pyrolysis of metal alginate, highly active catalysts for the Fischer-Tropsch synthesis (FTS) can be produced. However, evolution carbon (alginate) transition (Fe 3+ ) during remains largely unknown was herein corroborated with several advanced situ techniques. Initially, Fe reduced to 2+ , while bo...

The potential of polymeric nanostructures obtained by extruding polymer solutions through reusable anodic aluminum oxide (AAO) nanopores for the fabrication is investigated systematically to be able unveil impact structure on cell culturing. Thus, nanostructured Na-alginate and poly(vinyl alcohol) (PVA) polymers as well blended alginate/PVA hydrogels are fabricated. PVA fibers with different di...

Wound healing is an innate physiological response that helps restore cellular and anatomic continuity of a tissue. Selective biodegradable and biocompatible polymer materials have provided useful scaffolds for wound healing and assisted cellular messaging. In the present study, guar gum, a polymeric galactomannan, was intrinsically modified to a new cationic biopolymer guar gum alkylamine (GGAA...

Pb(II) is a representative heavy metal in industrial wastewater, which may frequently cause serious hazard to living organisms. In this study, comparative studies between alginate nanoparticles (AN) and quercetin-decorated alginate nanoparticles (Q-AN) were investigated for Pb(II) ion adsorption. Characterization of AN and Q-AN were analysed by transmission electron microscopy (TEM), Fourier tr...

BACKGROUND Acute myocardial ischemia results in scar formation with ventricular dilatation and eventually heart failure. Placental growth factor (PlGF) is reported to stimulate angiogenesis and improve cardiac function. In this study, it was hypothesized that intramyocardial injection of PlGF contained in nanoparticles can be released at the site of action for an extended time period as a susta...

Preparation of silver-alginate nanocomposite films as an antibacterial material has been carried out through the casting method colloidal silver-alginate. Colloidal was made by chemical reduction AgNO 3 precursor salts using microwave irradiation with alginate a stabilizer and reducing agent NaOH accelerator. The appearance brownish yellow color, due to addition variation , localized surface pl...

The Silver nanoparticles are well-known for their antimicrobial, anti-inflammatory wound healing abilities. We synthesized Silver nanoparticles using chemical reduction method and the formation of the silver nanoparticles was characterized by UV-Vis absorption spectroscopy, FT-IR and SEM techniques. The minimum inhibitory concentration of the synthesized nanoparticles was determined for both gr...

Drug delivery is the most essential feature in drug administration facility and the design of Nanosystems makes the action more consistent an appropriate. Polymer nano particles bind efficiently to the drug and disperse the drug proficiently into the system. The efficacy of many drugs is often limited by their potential to reach the site of therapeutic action. In most cases (conventional dosage...
