Formulation of Insect Chitosan Stabilized Silver Nanoparticles with Propolis Extract as Potent Antimicrobial and Wound Healing Composites

open access: yesInternational Journal of Polymer Science, Volume 2021, Issue 1, 2021., 2021
Skin wounds are frequently influenced with microbial infections and inflammation, which need innovative agents for disputing them. Chitosan (Csn) was extracted from larvae of BSF “black soldier fly, Hermetia illucens” and ethanolic propolis extract (Pro) was employed for synthesizing silver nanoparticles (Ag‐NPs), using facile biogenic protocol.

Current state of chitin purification and chitosan production from insects

open access: yesJournal of Chemical Technology &Biotechnology, Volume 95, Issue 11, Page 2775-2795, November 2020., 2020
Abstract Chitin, and especially its deacetylated variant chitosan, has many applications, e.g. as carrier material for pharmaceutical drugs or as a flocculant in wastewater treatment. Despite its versatility and accessibility, chitin, the second most abundant polysaccharide on Earth, has so far been commercially extracted only from crustaceans and to a
