CAN TINY BOTS MAKE MUSCLE AND BONE?

摘要

The more we learn about mastering nature, the more we seem to learn that nature is the ideal model. For instance, everything, from the lustrous lining of an abalone shell to the delicate tracery of a nerve strand assembles itself from garden-variety raw materials, atom by atom and molecule by molecule. That fundamental biological ability is what nanotechnologists desperately wish to imitate and, being human, even wish to improve on as they labor to create medically useful structures at dimensions as tiny as a nanometer—about 1/50,000 the width of a human hair.
