University of Illinois engineers have developed tiny “bio-bot” hybrid machines that swim like sperm, the first synthetic structures that can traverse the viscous fluids of biological environments on their own, according to the engineers.
The devices are modeled after single-celled creatures with long tails called flagella — for example, sperm. The researchers begin by creating the body of the bio-bot from a flexible polymer. Then they culture heart cells… read more
