Medical nanorobot. Computer artwork of a medical nanorobot injecting a drug into an infected cell in a human body. The cell is a T-cell, a type of white blood cell that mediates cellular responses of the immune system. Some T-cells are affected by HIV (human immunodeficiency virus), the virus that causes AIDS (acquired immune deficiency syndrome). The drug may be treating the cell for infection by HIV. This is an example of the future development of microscopic robot technology to treat diseases in new ways.
