The Nanotechnology is being used in developing countries to help and treat disease conditions and prevent health care issues. The common term of nanotechnology is Nanomedicine. The Nanomedicine is a branch of medicine which applies the knowledge and tools of nanotechnology to the prevention and treatment of disease conditions. The Nanomedicine involves the use of nanoscale materials, such as biocompatible nanoparticles and nanorobots, for the diagnosis of the disease, delivery of the drug, for sensing or actuation purposes in a living organisms. The Nanomedicine is the application of nanotechnology, which often described as technologies under 1000 nm, in the health care sciences. Well the researchers have been using nanomedicine to the target microbes, with a appropriate result in vitro and as a potential innovation to the field of antimicrobials
