Zinc oxide nanoparticles: Biological synthesis and biomedical applications

Nanotechnology is termed as a result of the synthesis, characterization, exploration, and application of nano-sized materials in the event of science and technology. In recent years, zinc oxide nanoparticles (ZnO-NPs) as an important ceramic materials are utilized in completely different industrial sectors such as medication, cosmetic materials and concrete, opposed microorganism, textile and automotive industries. Many chemical and physical methods were applied for preparing of ZnO-NPs but biological methods as “green” routes in different substrates (e.g., microorganisms, enzymes, bacteria, and plant extracts) are potentially steered as eco-friendly alternatives in comparison with chemical and/or physical techniques. At the present, ZnO-NPs are being investigated as associates of antibacterial agents in each microscale and nanoscale formulation. The ZnO-NPs are widely wont to treat a range of different skin conditions and have anticancer properties. In addition, ZnO-NPs have emerged as a suitable tool in drug delivery and sensing horizon. In this review, we summarize the green and biological synthesis methods of ZnO-NPs and investigation of their biomedical applications.
