An overview of green synthesis of zinc oxide nanoparticle by using various natural entities

ZnO NPs have gained significant attention due to their unique various properties such as drug delivery, bio-sensing and promising bio-medical applications as well as other uses in different fields including photo-catalytic applications and anti-microbial activities. Different conventional techniques used toxic chemicals that cause innumerable health endangers owing to their toxicology and hazarding severe efforts for surroundings, but biological synthesis techniques are free of toxins. In the biogenic approach, various natural entities including extracts, micro-organisms and proteins have been employed as capping and reducing agents during the synthesis of NPs. These bio-sources have attracted researchers due to their influence on the structure, shape and size of prepared NPs. Among all, plant-mediated synthesis of ZnO NPs is more useful and easy to synthesize. The green synthesis of ZnO NPs using various bio-sources including microorganisms, plant extracts, and other proteins, their formation, and work in this field has been summarized in this article.

Automated summary

ZnO nanoparticles (NPs) have attracted significant attention due to their unique properties and potential applications in drug delivery, bio-sensing, and other fields. In contrast to conventional techniques that use toxic chemicals, biological synthesis techniques using natural entities as capping and reducing agents offer a safer and more environmentally friendly approach. Among these approaches, plant-mediated synthesis of ZnO NPs is especially useful and easy to perform.
