✦ Synopsis

Abstract

Summary: Novel synthesis methods for the preparation of quaternary piperazine derivatives of chitosan were developed. Quaternary ammonium moiety can be selectively inserted into either one or both of the piperazine nitrogens, yielding structurally uniform chitosan derivative structures. Water‐soluble end products were thoroughly characterized with FT‐IR, ^1^H NMR, ^13^C NMR and 2D ^1^H‐^13^C HSQC NMR. The molecular weights of the end products were determined by GPC with triple detection.

## Abstract The objective of this work was to characterize a novel quaternary chitosan derivative [__O__‐(2‐hydroxyl) propyl‐3‐trimethyl ammonium chitosan chloride (__O__‐HTCC)] nanoparticle system. __O__‐HTCC nanoparticles were prepared with a simple and mild ionic gelation method upon the additio
