3We will address and propose themethod of entry into the body, means of propulsion, means of maintaining a fixedposition while operating, control of thedevice, power source, means of locatingsubstances to be eliminated, mans of doing the elimination and how to removethe device from the body afterward.
GIST OF NANOMEDICINE:
It is the application of nanotechnology (engineering of tinymachines) to the prevention andtreatment of disease in the human bodys.More specifically, it is the use of engineered nanodevices andnanostructures to monitor, repair,construct and control the humanbiological system on a molecular level.The most elementary of nanomedicaldevices will be used in the diagnosis of illnesses. A more advanced use of nanotechnology might involve implanteddevices to dispense drugs or hormonesas needed in people with chronicimbalance or deficiency states. Lastly,the most advanced nanomedicineinvolves the use of
asminiature surgeons. Such machinesmight repair damaged cells, or get insidecells and replace or assist damagedintracellular structures. At the extreme,nanomachines might replicatethemselves, or correct geneticdeficiencies by altering or replacingDNA (deoxyribonucleic acid) molecules.
Introduce the device into thebody:
We need to find a way of introducing thenanomachine into the body, andallowing it access to the operations sitewithout causing too much ancillarydamage. We have already made thedecision to gain access via thecirculatory system.The first is that the
of thenanomachine determines the minimumsize of the blood vessel that it cantraverse. We want to avoid damaging thewalls of whatever blood vessel thedevice is in, we also do not want toblock it much, which would either causea clot to form, or just slow or stop theblood flow. What this means is that thesmaller the nanomachine the better.However, this must
