Antimicrobial nanotechnology is a rapidly growing field of research that applies nanotechnology to the development of materials, devices, and systems that can prevent, detect, or destroy microbial pathogens such as bacteria, viruses, and fungi. These nanotechnology-based solutions can be used to reduce the spread of infectious diseases and improve public health. Examples of antimicrobial nanotechnology applications include nanomaterials that can be used to create self-cleaning surfaces, nanosensors that can detect the presence of bacteria, and nanodevices that can deliver antimicrobial drugs to target sites.
