ABSTRACT
In this study, chitosan nanoparticles (CTS NPs) have been suscessfully
combined with Carica papaya leaves (CPLs) extract for 30 min at
room temperature. The prepared chitosan nanoparticles (CTS
NPs)/Carica papaya leaves (CPLs) extract have been characterized by
UV-vis, FTIR, SEM and TEM. The result showed these CTS
NPs/CPLs extract obtained with the average particle size of ~20-50
nm. Moreover, the synthesized CTS NPs/CPLs extract also showed
efficient their anti-organism activity for the killing of yellow snails
occurred completely after 24 h. The presence of a small powder
amount (500 mg) of chitosan nanoparticles (CTS NPs)/Carica papaya
leaves (CPLs) extract in (5 L) water was enough to inhibit and kill
yellow snails completely only after 24 h.
Keywords: Chitosan nanoparticles (CTS NPs), Carica papaya leaves (CPLs) extract, yellow snails, biomaterial, anti-organisms.
