The amazing uses of diamonds never cease. Business Week reported that scientists believe that diamond coatings could one day be used to build tiny micro-machines that zip through your blood stream dispensing drugs throughout your body.
A team of researchers announced that they had fashioned a one-square-millimeter mechanical drive out of a diamond. Scientists think that diamond would work well on microscopic machines for two reasons. Since it is made of carbon, it can be easily ingested or implanted or implanted inside the human body. And it is so hard that diamond-coated machines last 10,000 times longer than those made of silicon.
