Nanomotor small enough for a human cell spins at 18,000 rpm

05/21/2014 | CNET

A new nanomotor small enough to fit into a human cell can sustain a spin speed of 18,000 rpm for up to 15 hours. The tiny motor (under one micrometer) developed at the University of Texas' Cockrell School of Engineering is envisioned as a mixer and pump for biochemicals. "We were able to establish and control the molecule release rate by mechanical rotation, which means our nanomotor is the first of its kind for controlling the release of drugs from the surface of nanoparticles," said Donglei Fan, the lead researcher and assistant professor of mechanical engineering.
