Abstract

Chitosan nanoparticles were made using acid solvents (formic acid) and crosslin king agents (tripolyphosphate) by ionic gelation. This method based on electrostatic interactions between the cations of the chitosan amine group and the polyanion of the crosslinking agent. Nanochitosan were prepared by using formic acid so/vents (26.32, and 36 mmol) and tripolyphosphate cross/inking agents (/.2, 1.8, and 2.4 mmol) with 3% (wlv) chitosan . The samples characterization using PSA (particle Size Analyzer). The nanochitosan has particles size 36.24 - 212.12 11m. It can used for antimicrobial agents in food packaging, drug delivery, and adsorp tire metals in water treatment. Chitosan nanoparticles having small particle diameters and low polydispersity indexes can only be obtained if the use of acid format concentration is inversely proportional to the concentration of the tripolyphosphate crosslinking agent
