NANOROBOTS
NANOROBOTS.doc (Size: 560 KB / Downloads: 49) ABSTRACT: The human body is basically an extremely complex system of interacting molecules (i.e., a molecular machine), the technology required to truly understand and repair the body is molecular machine technology. A natural consequence of this level of technology will be the ability to analyze and repair the human body as completely and effectively as we can repair any conventional machine today Nanotechnology is “Research and technology development at the atomic, molecular and macromolecular levels in the length scale of approximately 1 -100 nanometer range, to provide a fundamental understanding of phenomena and materials at the nanoscale and to create and use structures, devices and systems that have novel properties and functions because of their small and/or intermediate size.” NANOMEDICINE: It is the application of nanotechnology (engineering of tiny machines) to the prevention and treatment of disease in the human bodies. More specifically, it is the use of engineered nanodevices and nanostructures to monitor, repair, construct and control the human biological system on a molecular level. Introduce the device into the body: We need to find a way of introducing the nanomachine into the body, and allowing it access to the operations site without causing too much ancillary damage. The first is that the size of the nanomachine determines the minimum size of the blood vessel that it can traverse. However, this must be balanced against the fact that the larger the nanomachine the more versatile and effective it can be. This is especially important in light of the fact that external control problems become much more difficult if we are trying to use multiple machines, even if they don't get in each other's way. Movement of the device : We need two types of sensors. Long-range sensors will be used to allow us to navigate to the site of the unwanted tissue. We must be able to locate a tumor, blood clot or deposit of arterial plaque closely enough so that the use of short-range sensors is practical. These would be used during actual operations, to allow the device to distinguish between healthy and unwanted tissue.. Control the device: we consider the case of internal sensors. These sensors will be of two types. The first type will be used to do the final navigation. The second type of sensor will be used during the actual operation, to guide the microrobot to the tissue that should be removed and away from tissue that should not be removed. (1).Chemical: Chemical sensors can be used to detect trace chemicals in the bloodstream and use the relative concentrations of those chemicals to determine the path to take to reach the unwanted tissue. (2).Spectroscopic: This would involve taking continuous small samples of the surrounding tissue and analyzing them for the appropriate chemicals. This could be done either with a high-powered laser diode or by means of an electrical arc to vaporize small amounts of tissue. (3).TV camera:This method involves us having a TV camera in the device and transmitting its picture outside the body to a remote control Means of treatment: The treatment for each of the medical problems is the same in general; we must remove the tissue or substance from the body. Alternately, we can destroy the substance before allowing the body to eliminate the results. (1).Physical removal: This method can be effective in the treatment of arteriosclerosis. In this case, a blade, probe or edge of some sort can be used to physically separate deposits of plaque from the artery walls. In the case of tumors, the problem is more serious. The act of physically shredding or even just breaking loose clumps of cells can result in the cancer metastasizing throughout the body. One possible solution is to filter the cancerous cells out of the blood immediately downstream of the tumor. CONCLUSION: Nanomedicine will eliminate virtually all common diseases of the 20th century, virtually all medical pain and suffering, allow extension of human capabilities, especially our mental abilities. A nanostructured data storage device about the size of a human liver cell implanted in the brain could store a large amount of data and provides extremely rapid access to this information. Human beings who have a reasonable prospect of living many "normal" lifetimes will learn patience from experience, and will be extremely unlikely to risk those "many lifetimes" for any but the most compelling of reasons.Finally, and perhaps most importantly, no actual working nanorobot has yet been built. |
