The Effect of Tripolyphosphate (TPP) Volumes on the Synthesis of Chitosan Nanoparticles Using Ionic Gelation Method

Abstract

The effect of different volumes of tripolyphosphate (TPP) on the synthesis of chitosan nanoparticles (NPs) was evaluated. The synthesis was performed using the ionic gelation method with a 0.5% chitosan solution and 1% TPP. A particle size analyser (PSA) was used to obtain the size of the chitosan NPs while a Fourier Transform Infrared (FTIR) spectrophotometer was utilized to explore the functional groups of the NPs. The results showed that the average size of chitosan
