Better Living Through Nanotech.

“A team of chemists and engineers accomplished the feat by inserting tiny synthetic motors inside living cells, moving them around with ultrasonic waves and steering them magnetically. Clearly, it’s not as elegant as the self-propelled, self-guided nanobots envisaged by futurists and scifi, but it’s an important first step. These same basic principles could conceivably be refined and upgraded.”

A glimpse of the future: A Penn State team manage to insert synthetic nanomotors into living cells for the first time. “We might be able to use nanomotors to treat cancer and other diseases by mechanically manipulating cells from the inside. Nanomotors could perform intracellular surgery and deliver drugs noninvasively to living tissues.”
