Methods of ZnO nanoparticles synthesis

Zinc oxide nanostructures are interesting nanomaterials with a wide range of applications. Since the physical and

chemical properties of ZnO nanoparticles are influenced both by their shape and size, a control of morphology

of ZnO structures is needed for their commercial usage. Different chemical, physical, and biological methods used

to produce ZnO nanostructures can be found in the literature. The production of ZnO nanoparticles using so-called

green methods, using, for example, plant extracts or living organisms, is being investigated as these methods

are environmentally friendly and of low-cost. This review also discusses the trends in the biological synthesis of

semiconducting nanoparticles.
