ABSTRACT

Capping agents play a vital role in the synthesis of nanoparticles. Capping agents are often used to prevent the aggregation, controlling the size, shape and properties of nanoparticles. Commonly used capping agents are polyvinyl alcohol, polyvinyl pyrrolidone, polyethylene glycol, proteins and phenolic compounds. Among a variety of nanoparticles, zinc oxide nanoparticles has worldwide advantages because of its marvelous physical and chemical properties. ZnO nanoparticles are synthesized by various techniques. This novel review highlights the comparison between capping agents used in both chemical and biological synthesis of ZnO nanoparticles. This review provides important information about the role of capping agents on the size and morphology of ZnO nanoparticles also it is found that green synthesis leads to ecofriendly nanoparticle whereas chemical synthesis leads to toxic and non-ecofriendly nanoparticle.

Key words: zinc oxide, capping agents, synthesis
