Nanowerk News (Honolulu, Jan. 17) -- The alien world of aquatic micro-organisms just got new residents: synthetic self-propelled swimming bio-bots. A team of engineers has developed a class of tiny bio-hybrid machines that swim like sperm, the first synthetic structures that can traverse the viscous fluids of biological environments on their own. Led by Taher Saif, the U. of I. Gutgsell Professor of mechanical science and engineering, the team published its work in the journal Nature Communications.
