ABSTRACT
Nanotechnology is a field of science and engineering whose ultimate aim is to build robots smaller than living cells with the ability to arrange individual atoms into any physically possible pattern. The science of developing materials at the atomic and molecular level in order to imbue them with special electrical and chemical properties. The early genesis of the concept of nanomedicine sprang from the visionary idea that tiny nanorobots and related machines could be designed, manufactured, and introduced into the human body to perform cellular repairs at the molecular level. Nanomedicine today has branched out in hundreds of different directions.
INTRODUCTION
A nanorobot is a nanotechnological robot also called a nanite, which is a mechanical or electromechanical device whose dimensions are measured in nanometres (millionths of a millimeter).
Nanorobots are nanodevices that will be used for the purpose of maintaining and protecting the human body against pathogens. They will have a diameter of about 0.5 to 3 microns and will be constructed out of parts with dimensions in the range of 1 to 100 nanometers. Instead, medical nanorobots may be manufactured in carefully controlled nanofactories in which nanoscale machines are solidly integrated .
NANO-ROBOTS COMMUNICATION
The requirements of a nanorobot that would be inserted in a human body is that it must be mobile and have powerful navigation system, due to its functions in the human bloodstream and in the tissues. It may have a wide range of sensors to navigate through human body and to identify molecules and cells fast. It may have powerful transport subsystem to deliver molecules .It should also have wide range of computer-guided nano-manipulators. It may be manufactured from flawless diamonded due to bio-capability with human body. It may have broadcasting system which can connect to other nanorobots. Finally, it may have long telescopic manipulators to hold cells or surfaces.
FIELDS OF APPLICATION
Medical nanodevices could augment the immune system by finding and disabling unwanted bacteria and viruses. When an invader is identified, it can be punctured, letting its contents spill out and ending its effectiveness. If the contents were known to be hazardous by themselves, then the immune machine could hold on to it long enough to dismantle it more completely. Devices working in the bloodstream could nibble away at arteriosclerotic deposits, widening the affected blood vessels. Cell herding devices could restore artery walls and artery linings to health, by ensuring that the right cells and supporting structures are in the right places. This would prevent most heart attacks.
FUTURE NANOROBOTICS
In the longer term, perhaps 10 to 20 years from today, the earliest molecular machine systems and nanorobots may join the medical armamentarium, finally giving physicians the most potent tools imaginable to conquer human disease, ill health, and aging. Organic building materials.
CONCLUSIONS
Nanorobots monitoring nutrient concentrations in a three dimensional workspace is a possible application of nanorobots in medicine, among other biomedical problems. One interesting nanorobot application is to assist inflammatory cells leaving blood vessels to repair injured tissues... Nanorobots equipped with nanosensors could be developed to detect glucose demand in diabetes patients. Nanorobots could also be applied in chemotherapy to combat cancer through superior chemical dosage administration and a similar approach could be taken to enable nanorobots to deliver anti-HIVdrugs. Such drug-delivery nanorobots have been termed "pharmacytes”.
