Nanotechnology in Medicine
September 1st 2007 04:08
Small is beautiful but with nanotechnology small can become powerful. Disease and ill health are largely caused by damages at the molecular and cellular level. Today's surgical tools are, at this scale, large and crude and from the viewpoint of a cell, even a fine scalpel is a blunt instrument more suited to tear and injure than heal and cure. Modern surgery works only because cells have a remarkable ability to regroup, bury their dead and heal over the injury.
Nanotechnology, "the manufacturing technology of the 21st century," will help build a broad range of complex molecular machines (including, molecular computers). It will let us build fleets of computer controlled molecular tools much smaller than a human cell and built with the accuracy and precision of drug molecules. Such tools will let medicine, for the first time; intervene in a sophisticated and controlled way at the cellular and molecular level. They could remove obstructions in the circulatory system, kill cancer cells, or take over the function of sub cellular organelles. Just as today we have the artificial heart, so in the future we could have the artificial mitochondrion
