EFFECT OF CROSSLINKED CHITOSAN AS A CONSTRAINED VOLUME ON THE IN VITRO CALCIUM CARBONATE CRYSTALLIZATION

The present work deals with the effect of the constrained volume given by crosslinked chitosan (CHI) as a sphere on the in vitro CaC0(3) crystallization. Crosslinked CHI was obtained with formaldehyde (FA), glutaraldehyde (GA), epichlorhydrine (EPCH) and poly (propylene glycol) diglycidyl ether (PPD...
