The smallest, fastest and longest-running tiny synthetic motor have built by a group of researchers.
The finding is an important step toward developing miniature machines that could one day move through the body to administer insulin for diabetics when needed, or target and treat cancer cells without harming good cells, the team said.
The nanomotor is 1 micrometer in size, which could fit inside a human cell and is capable of rotating for 15 continuous hours at a speed of 18,000 RPMs, the speed of a motor in a jet airplane engine. But, nanomotors run significantly more slowly, from 14 RPMs to 500 RPMs, and have only rotated for a few seconds up to a few minutes.
Researchers coated the nanomotor's surface with biochemicals and initiated spinning to test its ability to release drugs. They found that the faster the nanomotor rotated, the faster it released the drugs. So, it gives a hope and dramatic change in the health field can expect soon...
