Contolling Artificial nano-robots from inside living cells

The last two years have been filled with discussion on the potential for nanotechnologies; and it seems that some of these promises are just beginning to ripen into reality.

For the first time ever, researchers at Penn State have put Nanorobots inside human cells and have controlled the nanorobots. These researchers used gold nanorods for their researcher. They used ultrasonic waves to control the rods.

This video shows the researchers controlling the nanorobots to

Will Nanobots replace neurons ?

A computer animation of a possible future nanomedical procedure where a nanobot replaces a damaged neuron has been published on YouTube (see below) in 2007.

Although this can look very "cool",  This animation conveys a realistic - nor even a futuristic - concept for the possible applications of nanotechnology. It does not contribute to a constructive education of the public on Nanotechnologies.  Surprisingly, this video scores 318 "likes" and 19 "dislikes".
