ABSTRACT
Many studies have been conducted over the last several decades to assess the benefits and disadvantages of various nanoparticle production technologies. Because of their extraordinary optical and electrical capabilities, several nanoparticles have attracted growing interest. The processes used to create nanomaterials have a significant impact on their optical, electrical, and chemical properties. Some materials are less costly than metals like gold and silver, and they also have high photocatalytic and antibacterial performances. This chapter focuses on nanoparticles’ significance as an effective antimicrobial and their modes of action. Furthermore, the photocatalytic and antimicrobial mechanisms of nanoparticles are also presented and the uses of nanopesticides as well as prospects and challenges of nanopesticide formulation and application in plant pest and disease management have been discussed.
