Nanomotors that are controlled, for the first time, inside living cells | KurzweilAI
February 23, 2014Posted by on
Penn State University chemists and engineers have, for the first time, placed tiny synthetic motors inside live human cells in a lab, propelled them with ultrasonic waves, and steered them magnetically.
The Penn State nanomotors are the closest so far to a “Fantastic Voyage” concept (without the miniature people).
The nanomotors, which are rocket-shaped gold rods ~300 nanometers in diameter and ~3 microns long, move around inside the cells, spinning and battering against the cell membrane.
The nanomotors are activated by resonant ultrasound operating at ~4 MHz, and show axial propulsion as well as spinning.
