Chitosan lecithin nanoparticles
WebAmong nanoparticle-based drug delivery formulations, lecithin/chitosan liposomes are promising candidates because of their biocompatibility, biodegradability and bioadhesion properties. Lecithin is a mixture of highly biocompatible phospholipids, while chitosan represents one of the most used polymers in pharmaceutical formulations. WebThe objective of this work is to formulate a zein-based nanocomposite for the delivery of natural polyphenols. A proprietary atomizing/antisolvent precipitation (AAP) process was used to prepare carboxymethyl chitosan (CMC)-coated zein/soy lecithin (SL) nanoparticles (ZLC NPs). At a suitable mass ratio of ze
