Preparation, Characterization, and Insecticidal Activity of Avermectin-Grafted-Carboxymethyl Chitosan
Avermectin-grafted-N,O-carboxymethyl chitosan (NOCC) derivative was obtained by esterification reaction using dicyclohexylcarbodiimide (DCC) as dehydrating agent and 4-methylaminopyridine as catalyst. The structures of the conjugate were confirmed by FT-IR, (1)H NMR, and XRD. Insecticidal activities against armyworms, carmine spider mites, black bean aphids, and brown plant hoppers were investi...
متن کاملPreparation of carboxymethyl chitosan in aqueous solution under microwave irradiation.
Carboxymethyl chitosan was prepared by reacting chitosan with chloroacetic acid in water under microwave irradiation. The effect of the reaction conditions was investigated and optimal conditions were identified. The influence of mass ratio of chloroacetic acid to chitosan, microwave power and pH on the degree of substitution or intrinsic viscosity were further studied. The degree of substituti...
متن کاملDaunorubicin-loaded Chitosan Microparticles - Preparation and Physicochemical Characterization
The present study deals with the preparation and characterization of chitosan microparticles as a drug delivery system for daunorubicin. The microparticles are prepared by the suspension method and their properties are improved by covalent crosslinking using glutaraldehyde. The obtained spherical microparticles with size of 300 μm are loaded with daunorubicin. The мorphology and chemical compos...
متن کاملPreparation of Antimicrobial Paper Sheets Using Chitosan
The purpose of this study was the antimicrobial functionalization of paper pulp with natural biopolymer chitosan. Laboratory paper sheets were prepared for this purpose from paper pulp with incorporated chitosan. The prepared paper sheets were analysed regarding amino group content, mechanical properties and hydrophilicity. All of these parameters are important for hygienic applications of pape...
متن کاملPrevention of postsurgical adhesions with N,O-carboxymethyl chitosan: examination of the most efficacious preparation and the effect of N,O-carboxymethyl chitosan on postsurgical healing.
BACKGROUND Adhesion formation after operation can result in major complications. We have previously demonstrated that N,O-carboxymethyl chitosan (NOCC) is an effective inhibitor of postsurgical peritoneal adhesion formation. However, the optimal form of NOCC (i.e., cross-linked gel versus solution), as well as the best time of administration for optimal reduction in adhesion development, was no...
