Chitosan is a green (natural, abundant, biodegradable, biocompatible)
biopolymer that can be formulated to encapsulate a variety of therapeutic compounds. This study aimed to investigate chitosan nanoparticles (NPs) as a means of
improving delivery of the clinically used anti-cancer agent doxorubicin (Dox) and
the preclinical lead compound Dz13 oligonucleotide together.
