n-sodium acrylate-o-carboxymethyl chitosan [cmch-g-paa(na)] bound fe3o4 nanoparticles were developed as a novel magnetic nanoparticles with an ionic structure that can be potentially used in many fields. cmch-g-paa (na) was obtained by grafting of sodium polyacrylate on o-carboxymethyl chitosan, which is an amphiphilic polyelectrolyte with the biocompatibility and biodegradability properties. a...

The potential risk of infection due to the biofilm formation on implant surface constitutes one of the drawbacks of hydroxyapatite ossicular chain prostheses. The current study explores the use of chitosan nanoparticles as an antimicrobial agent impregnated in hydroxyapatite to prevent pathogenic colonization and subsequent suboptimal outcomes associated with ossicular reconstruction surgeries....

In this paper, Fe3O4-chitosan nanoparticles were prepared by the immobilization of chitosan on the surface of Fe3O4 nanoparticles. Then, the 5-substituted hydantoins were synthesized from the condensation of aldehyde derivatives, ammonium carbonate and zinc cyanide as a well-known cyanating agent by the magnetic Fe3O4-chitosan nanoparticles under neat conditions. Fe3O4-Chitosan nanocatalyst as ...

Two liquids are separated by a nanoporous membrane and one liquid is made to flow into the other, causing nanoparticles to be formed at the exits of the nanopores. In particular, we report the generation of nanoparticles of the biodegradable polysaccharide polymer chitosan by placing the chitosan in a low pH aqueous solution that is flowed into a high pH aqueous solution. The size of the nanopa...

In recent years, chitosan nanoparticles have been studied widely for protein delivery. In this study, Hemiscorpius lepturus (HL) venom was encapsulated in chitosan nanoparticles. The aim of the present work was to carry out a systematic study for preparing biocompatible and biodegradable nanoparticles for loading HL scorpion venom and to evaluate their potential as an antigen delivery system. I...

Naturally occurring polymers, particularly of the polysaccharide type, have been used pharmaceutically for the delivery of a wide variety of therapeutic agents. Chitosan, the second abundant naturally occurring polysaccharide next to cellulose, is a biocompatible and biodegradable mucoadhesive polymer that has been extensively used in the preparation of micro-as well as nanoparticles. The prepa...

Polysaccharides and other cationic polymers have been recently used in pharmaceutical research and industry for their properties to control the release of antibiotics, DNA, proteins, peptide drugs or vaccines and have been also extensively studied as non viral DNA carriers for gene delivery and therapy. Among them, chitosan is one of the most used because it promotes long term release of incorp...

The use of chitosan as a delivery carrier has attracted much attention in recent years. In this study, chitosan nanoparticles (CS-NP) and chitosan-ΦKAZ14 bacteriophage-loaded nanoparticles (C-ΦKAZ14 NP) were prepared by a simple coercavation method and characterized. The objective was to achieve an effective protection of bacteriophage from gastric acids and enzymes in the chicken gastrointesti...
