The present work described nanoparticles (NPs) made of oleoyl-carboxymethy-chitosan (OCMCS)/hyaluronic acid (HA) using coacervation process as novel potential carriers for gene delivery. An N/P ratio of 5 and OCMCS/HA weight ratio of 4 were the optimal conditions leading to the smallest (164.94nm), positive charged (+14.2mV) and monodispersed NPs. OCMCS-HA/DNA (OHD) NPs showed higher in vitro DNA...
Chitosan is widely explored as a gene delivery vehicle due to its ability to condense DNA, facilitate transport, and subsequent release allowing gene expression, as well as protecting the DNA. Here, we investigate the enhancement of chitosan–DNA dispersion stability while maintaining transfection efficacy by PEGylation of chitosan. Molecular properties of fully deacetylated chitosans and degree of...
