Particle size and size distribution of nanoparticles examined by DLS. A nanochitin sample, with a concentration of 0.0024% w/v, was prepared by diluting a stock of nanochitin suspension with DI water, then 1 mL of the dilution was examined by NanoSizer, ZS 90, and the pH of the dilution was not adjusted. The polydispersity index (PDI) was 0.246.
