Nano robotics describes the technology of producing machines or robots at the Nano scale. ‘Nanobot’ is an informal term to refer to engineered nano machines. Though currently hypothetical, Nano robots will advance many fields through the manipulation of Nano-sized objects.
The field of medicine is expected to receive the largest improvement from this technology. This is because nanotechnology provides the advantage of transporting large amounts of nanorobots in a single injection. This will improve disease monitoring and treatment whilst reducing the need for invasive procedures.
Nano robotics Applications for Cancer Detection and Therapy:
As cancer survival rates improve with early detection, Nano robots designed with enhanced detection abilities will be able to increase the speed of a cancer diagnosis and therefore enhance the prognosis of the disease.
Proposed designs currently include the employment of integrated communication technology, where two-way signaling is produced. This means that nanobots will respond to acoustic signals and receive programming instructions via external sound waves along with transmitting data they have accumulated.
Targeted treatment. Current cancer treatments have severe side effects caused by the destruction of healthy cells. Targeted treatment can be formed by designing Nano robots with chemotactic sensors on their surface which correspond to specific antigens on the cancer cells.
Nano robotics Applications for Biohazard Defense:
Nanobots with protein based biosensors will be able to transmit real-time information in areas where public infrastructure is limited and laboratory analysis is unavailable. This is particularly applicable for biomedical monitoring of areas devastated by epidemic disease as well as in remote or war torn countries during humanitarian missions.
Nano robotics may also reduce contamination and provide successful screening for quarantine. The increased concentration would trigger the Nano robot prognostic protocol which sends electromagnetic back propagated signals to portable technology such as a mobile phone. The information would then be retransmitted via the telecommunication system providing information on the location of the infected person, increasing the speed of contamination quarantine.
Nano robotic Applications in the Field of Hematology:
Reciprocates are hypothetical nanobots engineered to function as artificial red blood cells. In emergencies where a patient stops breathing and blood circulation ceases, reciprocates could be injected into the blood stream to transport respiratory gases until the patient is stabilized.
Current research is developing Nano robotic applications for the field of hematology. This ranges from developing artificial methods of transporting oxygen in the body after major trauma to forming improved clotting capabilities in the event of a dangerous hemorrhage. Clottocytes are another type of nanobot which function as artificial platelets for halting bleeds.
The clotting ability of one injection of clottocytes would be 10,000 times more effective that an equal volume of natural platelets.
