Bioinspired Metal Nanoparticles for Microbicidal Activity


Bioinspired Metal Nanoparticles for Microbicidal Activity

Rajalakshmi Subramaniyam, Shairam Manickaraj, Prasaanth Ravi Anusuyadevi

The broad reception for nanotechnology is due to their appreciable size and versatile applications in the interdisciplinary areas. In this modern era one of the major problems is microorganisms possessing antibiotic resistance, nanoparticles (NPs) are a lucrative option to solve this. In materials science, “green synthesis” has gained extensive attention as a reliable, sustainable, and eco-friendly protocol for synthesizing a wide range of materials, especially metals, and metal oxides nanomaterials, hybrid materials and bioinspired materials. As such, green synthesis is regarded as an important tool to reduce the destructive effects associated with the traditional methods for synthesis of nanoparticles commonly utilized in laboratory and industry. Bio-inspired NPs held edges over conventionally synthesized nanoparticles due to their low cost, easy synthesis and low toxicity. This chapter elaborates the developments on the biosynthesis of NPs using natural extracts with particular emphasis on their application as microbiocidal agents. This chapter has very specifically dealt with coinage metals such as Cu, Ag, Au due to their significance of antimicrobial activities. Succeeding, reported the developments in the synthetic methodologies of metal-oxide (Titanium dioxide, TiO2) nanoparticles using novel plant extracts with high medicinal value and their corresponding ability to degrade bacterial pathogens through advanced oxidation process (AOPs) based on heterogeneous photocatalysis.
