Abstract
As an antioxidant biopolymer, chitosan nanoparticles can be conjugated with other antioxidant agents to increase the potential applications of the resulting materials in a variety of sectors, including food, packaging, cosmetics, and other industries. In this research, terephthaldialdehyde was used to quickly create a novel oxime. The oxime was then connected to chitosan nanoparticles (CSNP) to acquire established biological characteristics. FTIR, 1H and 13C NMR all demonstrated the oxime’s production. The Schiff base of oxime on chitosan nanoparticles (CSNP-OX) was detected by FTIR, UV-Vis, DLS, FE-SEM-EDX, and TEM. The antioxidant activities of the CSNP and CSNP-OX were also analyzed; DPPH radical scavenging of CSNP-OX was higher than CSNP. These findings suggest that the CSNP-OX is a viable option for utilization in pharmaceuticals and food items for innovative uses.
期刊介绍：
"Polymer Bulletin" is a comprehensive academic journal on polymer science founded in 1988. It was founded under the initiative of the late Mr. Wang Baoren, a famous Chinese chemist and educator. This journal is co-sponsored by the Chinese Chemical Society, the Institute of Chemistry, and the Chinese Academy of Sciences and is supervised by the China Association for Science and Technology. It is a core journal and is publicly distributed at home and abroad.
"Polymer Bulletin" is a monthly magazine with multiple columns, including a project application guide, outlook, review, research papers, highlight reviews, polymer education and teaching, information sharing, interviews, polymer science popularization, etc. The journal is included in the CSCD Chinese Science Citation Database. It serves as the source journal for Chinese scientific and technological paper statistics and the source journal of Peking University's "Overview of Chinese Core Journals."
