Bacterial Motors Drive Microscopic Pumps

Bacteria spin their flagella like tiny motors to move. The University of Tokyo used this concept to create nanoscale pumps for drug delivery in pacemakers. Their 2024 prototype delivers anti-inflammatory medicine directly to implantation sites. Human testing could start within a year. These microscopic delivery systems target medication exactly where it’s needed most. Bacteria evolved these rotating propellers billions of years ago, achieving mechanical perfection on a scale humans still struggle to replicate.
