Maurstad G, Danielsen S, Stokke B
Biomacromolecules
. 2007 Mar;
8(4):1124-30.
PMID: 17330955
In this study the relative importance of valence and charge density of the polycation chitosan on the compaction process of DNA and xanthan is investigated. Chitosans with approximately equal valence...

Biochim Biophys Acta
. 2005 Jan;
1721(1-3):44-54.
PMID: 15652178
Chitosan-based gene delivery systems are promising candidates for non-viral gene therapy. A wide range of chitosans has been studied to optimize the properties of the DNA-chitosan complexes to yield high...

. 2004 Dec;
77(2):86-97.
PMID: 15612043
Polyelectrolyte complex (polyplex) formation was studied by employing tapping mode atomic force microscopy (AFM) and an ethidium bromide fluorescence assay. The polycations chitosan and poly-L-lysine were used to compact DNA...

Biomacromolecules
. 2004 May;
5(3):928-36.
PMID: 15132683
Chitosan is a nontoxic and biodegradable polysaccharide that has recently emerged as a promising candidate for gene delivery. Here the ability of various chitosans, differing in the fractional content of...
