Characterization of Polyhydroxybutyrate Nanoparticles

open access: yesIraqi Journal of Science, 2022
     Preparation of nanoparticles is one of the important ways to increase the biological effectiveness of materials. There are several methods to prepare the polyhydroxybutyrate (PHB) nanoparticles. Here, a new method is used based on exposing PHB to ultrasound waves under variable pH conditions.
