The green synthesis of supported noble metal nanoparticles is now the most exciting field for various catalytic applications as well as biomedical applications. In this paper we report a novel synthesis method of a polymer consisting of silver nanoparticles (AgNPs) using immobilized microorganisms in alginate beads. Microorganisms present in the polymer reduce aqueous AgNO3 to AgNPs which get t...

Abstract The newly engineered functional systems of nanotechnology implemented in food packaging minimize product loss by extending shelf life. incorporation nanostructured materials into formulations enhanced the existing characteristics increasing specific surface area these biopolymers. Natural biopolymers were regarded as greener, more sustainable, and environmentally friendly materials. St...

In the recent past, nanobiotechnology field has grown up tremendously with more applications because synthesis process will be practically possible techniques. Since, plant-derived biosynthesis of silver nanoparticles is superior since its eco-friendly, cost-efficient, speedy in nature. Alginate-based biodegradable nanocomposite films were prepared Celosia cristata leaf extracts (CC-AgNPs) and ...

Purpose. The antitumor activity of a novel alginate (ALG) polymer-based particle that contained paclitaxel (PTX) was evaluated using human primary breast cancer cells. Materials and Methods. PTX was combined with ALG in a nanoparticle as a drug delivery system designed to improve breast cancer tumor cell killing. PTX-ALG nanoparticles were first synthesized by nanoemulsification polymer cross-l...

In this study, the steady incompressible flow of a non-Newtonian sodium alginate (SA) fluid conveying copper nanoparticles (Cu) which flow within two vertical parallel plates is investigated by using the homotopy perturbation analytical scheme to solve the coupled nonlinear ordinary equations arising from the mechanics of the fluid. The developed analytical solutions are used to investigate the...

PURPOSE We prepared and characterized topical ophthalmic formulations containing brimonidine-loaded bioadhesive cationic chitosan or anionic alginate nanoparticles (NPs) for sustained release of brimonidine as once daily regimen for management of glaucoma. METHODS Nanoparticles were prepared using a spontaneous emulsification solvent diffusion method. Different concentrations of polymers, emu...

p-Cresol is an environmental pollutant due to its vast use, toxicity and persistence, nevertheless, its degradation in an enzyme is unclear. In this study, we used Pleurotus sp. isolate VLECK02 polyphenol oxidase (PPO) for the determination of p-cresol degradation. On the basis of UV, FT-IR and chromatographic (HPLC and GC-MS) analysis, 4-methylcatechol was identified as the main metabolite of ...

Bilayer films that combine chitosan and alginate, two natural polysaccharides, magnetic iron oxide nanoparticles (MNPs) were obtained. Physical microscopic observations revealed alginate interact strongly through their surfaces, which is attributed to the formation of a polyelectrolyte complex at interface. The diameter individual MNPs was about 10 nm, although in they appear arranged clusters ...

Fungal infections have become a major public health problem, growing in number and severity in recent decades due to an increase of immunocompromised patients. The use of therapeutic agents available to treat these fungal infections is limited by their toxicity, low bioavailability, antifungal resistance, and high cost of treatment. Thus, it becomes extremely important to search for new therape...

A new microsphere consisting of inorganic mesoporous silica nanoparticles (MSNs) and organic alginate (denoted as MSN@Alg) was successfully synthesized by air-dynamic atomization and applied to the intracellular drug delivery systems (DDS) of liver cancer cells with sustained release and specific targeting properties. MSN@Alg microspheres have the advantages of MSN and alginate, where MSN provi...
