This book focuses on nanomaterials with antibacterial properties. Antibacterial resistance is a growing concern that poses a serious threat to public health worldwide. This book looks at the fabrication, material's properties, and characterization of a range of metallic, bimetallic, and metal-oxide-based nanomaterials that can be exploited for their antimicrobial properties. A key focus of this book is its emphasis on 'green' synthesis of nanomaterials, as many conventional routes of nanomaterial fabrication do not fulfill key sustainability criteria in terms of their toxicity and lack of eco-friendliness. Additionally, this book introduces the application of nanoparticles to veterinary medicine. Given the ever-increasing global livestock population coupled with the emergence of drug-resistant pathogens of animal origin (bacterial, parasitic, and hemoprotozoa), the use of nanoparticles as antibacterial agents represents a paradigm shift in every aspect of veterinary care. Authored by scholars with combined expertise in nanomaterials and veterinary medicine, this book provides valuable information for researchers working on sustainable nanomaterials with antibacterial properties.
