Abstract Chitosan was degraded into low-molecular-weight chitosan (LWCS) using different concentrations of H2O2. Then different concentrations of tripolyphosphate (TPP) were incorporated to make nanochitosan. The effects of LWCS on nanochitosan particle size and the zeta potential are discussed. The cross-linking was best when the LWCS/TPP mass ratio was approximately 5:2, at which nanochitosan particles formed and the zeta potential measured at this moment was minimal. A lower molecular weight corresponded to a smaller nanoparticle size. Keywords: ChitosanDegradationNanoparticle sizeTripolyphosphateZeta potential
