Sustainable Nanomaterials as Promising Antibacterial Agents

The use of sustainable nanoparticles (NPs) as antibiotic substitutes has grown in popularity for the elimination of germs. The treatment of bacterial infections may be improved by the use of nanotechnology. The application of sustainable nanoparticles (NPs) can be observed in various fields, such as the inclusion of NPs in bactericidal coatings for medical products and implants, which serve the purpose of preventing infection and facilitating wound healing. Additionally, NPs are utilized in systems for delivering antibiotics to cure illnesses and for detecting bacteria to provide microbiological diagnostics, and antibacterial vaccines for the effective management of bacterial infections. These instances exemplify the diverse applications of sustainable NPs. The specific ways that sustainable nanoparticles (NPs) display antimicrobial qualities remain to be fully elucidated. However, the presently acknowledged mechanisms include oxidative stress induction, metal ion release, and non-oxidative processes. The development of antibacterial resistance necessitates the presence of multiple gene alterations within a single bacterial cell, which in turn requires the availability of various mechanisms to combat microbial pathogens. Consequently, the acquisition of resistance to nanoparticles (NPs) by bacterial cells presents a challenging endeavor. This chapter focuses on how sustainable nanoparticles (NPs) fight bacteria through antibacterial processes, along with an exploration of the factors that influence the antibacterial activity of nanomaterials.
