Latent Fingerprint Enhancement Using Tripolyphosphate-Chitosan Microparticles [PDF]

, 2013
Chitosan has been widely used in the preparation of microparticles for drug delivery; however, it has not been considered in forensic applications. Tripolyphosphate- (TPP-) chitosan microparticles were formed using ionotropic gelation in the presence of ...

Optimum conditions for the precipitation of chitosan oligomers with DP 5-7 in concentrated hydrochloric acid at low temperature

, 1999
Chitosan was partially hydrolysed with 35% hydrochloric acid for 2 h at 80 degrees C and the hydrolysate stored at - 20 degrees C after dilution with water to precipitate higher molecular weight (MW) chitosan oligomers.

Biological Activity of Chitosan Oligomers

Izvestiya of Saratov University. Chemistry. Biology. Ecology, 2008
The biological activity of chitosan oligomers of various molecular masses was examined on E.coli (АТСС 25922), S.aureus (АТСС 25923), and fungus Candida albicans (АТСС 10231). All the samples under study inhibited the growth of these microorganisms, especially S.aureus.
