Development and characterization of sodium alginate beads incorporating functionalized poly(acrylonitrile-co-styrene)/ carbon nanotubes for effective Fe(II) ion adsorption from aqueous solutions.

This study details the development and evaluation of sodium alginate-Poly(acrylonitrile-co-styrene)/ Carbon Nanotubes (SA-M*Poly(AN-co-ST)/CNTs) composite beads serve as a highly effective adsorbent for the removal of Fe(II) ions from water solutions. The composite was prepared through the modification and functionalization of poly(acrylonitrile-co-styrene) copolymer with carboxylic acid groups, Subsequently, carbon nanotubes (CNTs) and sodium alginate were integrated to create sturdy gel beads. The composite beads were characterized using SEM, FTIR, and BET surface analysis spectroscopy, revealing a specific surface area of 127.

Capsaicin/silica-infused polygalacturonic acid/polyvinyl alcohol nano-matrix for enhanced wound healing in skin injuries.

Wound healing is a complex physiological process, demanding advanced strategies for efficient tissue regeneration. To address this, we developed a novel nanofibrous matrix composed of polygalacturonic acid (PGA), polyvinyl alcohol (PVA), capsaicin, and zinc-doped mesoporous silica (Zn/MCM-41). This copolymeric matrix offers enhanced mechanical stability, controlled drug release, and improved cellular adhesion and proliferation, leading to effective tissue regeneration.

Preparation and Characterization of Chitosan Nanofiber: Kinetic Studies and Enhancement of Insulin Delivery System.

Insulin-loaded nanofibers were prepared using chitosan as a natural polymer. The loaded insulin with polyethylene oxide was used for preparing monolayer batch S1. Nanofiber S1 was coated by seven layers of film on both sides to form batch S2 as a sandwich containing Layer A (CS, PEG and PEO) and Layer B (PEG and PEO) using electrospinning apparatus.

Olive leaf extract-derived chitosan-metal nanocomposite: Green synthesis and dual antimicrobial-anticancer action.

In this study, we developed a novel nanocomposite by synthesizing zinc (ZnNPs), copper (CuNPs), and silver (AgNPs) nanoparticles using olive leaf extract and incorporating them into a chitosan polymer. This approach combines the biocompatibility of chitosan with the antimicrobial and anticancer properties of metal nanoparticles, enhanced by the phytochemical richness of olive leaf extract. The significance of our research lies in its potential to offer a biodegradable and stable alternative to conventional antibiotics and cancer treatments, particularly in combating multidrug-resistant bacteria and various cancer types.
