Comparative study on antimicrobial activity and biocompatibility of N-selective chitosan derivatives

N-selective derivatives of chitosan (CH) namely, N-methyl chitosan (NMC), trimethyl chitosan (TMC), diethyl methyl chitosan (DEMC) and carboxymethyl chitosan (CMC) were synthesized to study the effects of alkylation on antimicrobial property and biocompatibility. The derivatives were characterized by FT-IR confirming O-free alkyl substitution. XRD studies showed reduction in crystallinity and zeta potential measurement proved the increase in...
