Green Synthesized Plant-Based Metallic Nanoparticles for Antimicrobial and Anticorrosion Applications

Metal nanoparticles (MNPs) developed through green synthesis with various plant extracts have piqued the scientific community due to their antimicrobial and anti-corrosion properties. Several synthesis methods and characteristics have been suc-cessfully implemented and developed to evaluate the pharmacological properties and performance of these MNPs. This article discusses the synthesis and characteristics of plant-based metallic nanoparticles, the different types of plant-based metallic nanoparticles, and their prospective applications. This short review intends to understand, what is commonly reported in scientific papers about MNPs as an-timicrobial and anticorrosion agents, as well as highlight the essential parameters and procedures, which affect the antimicrobial and anticorrosion investigation of plant-based MNPs. However, despite the many antibacterial and anticorrosion ap-proaches reported in the literature, very few platforms have achieved large scale. The difficulty in attaining large-scale success could be due, in part, to the complex-ity of the problem and the various parameters. Therefore, systematic research will be required to establish a standardized, widely accepted validation methodology for synthesizing and characterizing plant-based metallic nanoparticles.
