Green Synthesized Plant-Based Metallic Nanoparticles for Antimicrobial and Anti-Corrosion Applications

Abstract

Metal nanoparticles (MNPs) developed through green synthesis with various plant extracts have piqued the scientific community due to their antimicrobial and anticorrosion properties. Several synthesis methods and characteristics have been successfully 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 review intends to understand, what is commonly reported in scientific papers about MNPs as antimicrobial 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 approaches 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 complexity 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.
