Nanorobotics is the technology of creating machines or robots at or close to the microscopic scale of a nanometer (10-9 meters). More specifically, nanorobotics refers to the still largely hypothetical nanotechnology engineering discipline of designing and building nanorobots, devices ranging in size from 0.1-10 micrometers and constructed of nanoscale or molecular components. Nanorobots will be basically used for the treatement in field of nanomedicine. An intresting utilization of nanorobots may be their attachment to transmigrating inflammatory cells or WBC, to reach inflamed tissues and assist in their healing process. A cream containing nanorobots may be used to cure skin disease. It can be also used for early diagnosis and targeted drug delivery for cancer biomedical instrumentation, surgery, pharmacokinetics, monitoring of diabetes, and health care. The devices could provide an effective long-term drug-free symptomatic treatment for asthma. The nanorobots can be used to prevent most heart attacks. Thus nanorobots applied to medicine hold a wealth of promise from eradicating disease to reversing the aging process (wrinkles, loss of bone mass and age-related conditions are all treatable at the cellular level); nanorobots are also candidates for industrial applications. They will provide personalised treatments with improved efficacy and reduced side effects that are not available today.
