Combining hyaluronic acid with chitosan enhances gene delivery [PDF]

open access: yes, 2014
The low gene transfer efficiency of chitosan-DNA polyplexes is a consequence of their high stability and consequent slow DNA release. The incorporation of an anionic polymer is believed to loosen chitosan interactions with DNA and thus promote higher ...
