[Nanotechnology is the study of extremely small structures, having size of 0.1 to 100 nm. Nano medicine is a relatively new field of science and technology. Nanomedicine seeks to deliver a valuable set of research tools and clinically useful devices in the near future. Brief explanation of various types of pharmaceutical nano systems is given. The process of drug delivery using nanotechnology is described here. Cancerous cells can also be identified and cured using nanotechnology. Process of implementation of nanotechnology in neurology is also described here. Nanotechnology can be used in blood purification also. Brief description about diagnostic nanomaterial is given. Nanomaterials can be used to treat blood disorder diseases. Nanomaterials can thus play a key role in saving millions of lives
