Further, we have compared polyplexes of ultrapure chitosan (UPC) of preferred molecular structure with those of optimised polyethylenimine (PEI) polyplexes in vitro and after intratracheal ...

Chemical structure of chitosan. Image Credits: Wikimedia Commons Research carried out in 2006 then focused on the in vitro and in vivo interaction of chitosan nanoparticles (CSNPs), as a new ...

The team tackled this challenge by fabricating chitin hydrogel with biomimetic structure through the chemical transformation of chitosan, a water-soluble deacetylated derivative of chitin.
