Nanorobots being Developed to Repair Cells

Nanotechnology researchers are building nanorobots for a number of health related applications. Perhaps the most exciting of these possibilities is the potential for repairing our bodies at the cellular level. Techniques for building nanorobots are being developed that should make the repair of our cells possible.

Nanorobots would be able to repair damaged DNA and allow our cells to function correctly. These little guys could be built to perform surgical procedures more precisely. By working at the cellular level, such nanorobots could prevent much of the damage caused by the comparatively clumsy scalpel.

This capability to repair DNA and other defective components in our cells goes beyond keeping us healthy: It has the potential to restore our bodies to a more youthful condition. This concept is discussed in Eric Drexler's Engines of Creation. Drexler states:

“Aging is fundamentally no different from any other physical disorder; it is no magical effect of calendar dates on a mysterious life-force. Brittle bones, wrinkled skin, low enzyme activities, slow wound healing, poor memory, and the rest all result from damaged molecular machinery, chemical imbalances, and mis-arranged structures. By restoring all the cells and tissues of the body to a youthful structure, repair machines will restore youthful health.”
