Preparation and evaluation of photocrosslinkable chitosan as a drug delivery matrix

Epichlorohydrin (1‐chloro‐2,3‐epoxypropane) was reacted with sodium azide in the presence of a phase transfer catalyst to obtain 1‐chloro‐2‐hydroxy‐3‐azidopropane, which was further coupled onto chitosan to prepare a photocrosslinkable derivative of the biopolymer. Elemental analysis and infrared (I...
