Characterization of chitosan nanoparticles extracted from maggot shell and paddy snail waste using the ionic gelation method

Abstract

Abstract The aim this study was to characterize of chitosan nanoparticles extracted from maggot shell waste and paddy snail waste using the ionic gelation method. The Scanning Electron Microscope of nanochitosan extracted from maggot shell showed heterogeneity in particle size ranging from 218.60 to 279.04 nm by 73.5%. SEM results of nanochitosan extracted from paddy snail waste showed ranging from 193.48 to 356.20 nm by 60.4% and 740.89 to 945.74 nm by 14.35%. The zeta potential of nanochitosan particles of maggot shell waste and paddy snail waste were found to be 9.7 mV and -28.9 mV, respectively. The source of chitosan nanoparticles might produce the difference of particle size and zeta potential of chitosan nanoparticles.
