ABSTRACT
In the last few years, nanomaterials have gained popularity due to their antibacterial properties. Different research studies have revealed that the effectiveness of the nanomaterials against microbes is increased if they are comprising of metals like Silver (Ag), Gold (Au), Copper (Cu), Zinc (Zn), Iron (Fe), Titanium (Ti), Magnesium (Mg), etc. Such materials can be synthesized by chemical, physical or biological methods. However, no matter what mode is adopted to prepare these nanomaterials, they possess a high biocidal impact against gram-positive and gram-negative bacteria as described by various studies. The current chapter is mainly focused on these aspects of the nanomaterials and especially elaborates the antibacterial activity of metallic nanomaterials (for metals including Silver (Ag), Gold (Au), Copper (Cu), Zinc (Zn), Iron (Fe) Titanium (Ti), Magnesium (Mg), etc.). The chapter will be helpful for researchers in building a correlation between metallic nanomaterial and their impact on MDR bacterial infections. Hence, finding multiple ways to produce antibacterial nanomaterials with desired properties and possible outcomes of being selective, cost-effective, efficient, non-toxic, environment-friendly, easier to prepare. However, more 442elaborative studies are required to explore the true potential and selective activity of nanomaterial against specific bacteria.
