Nanomotors Are Controlled, for the First Time, Inside Living Cells
10 February 2014 — For the first time, a team of chemists and engineers at Penn State University have placed tiny synthetic motors inside live human cells, propelled them with ultrasonic waves and steered them magnetically. It’s not exactly “Fantastic Voyage,” but it’s close. The nanomotors, which are rocket-shaped metal particles, move around inside the cells, spinning and battering against the cell membrane.

They look alive! Of course they aren’t. This has to become one of the great bioengineering videos of all time.
I attended a seminar about using gold nanoparticles like these to target brain tumours.
HeLa cells – poor Henrietta Lacks.
