Thanks for sending the link. I hadn't seen that.

One control mechanism might be something called "photolytic uncaging". The idea is that a chemical like a neurotransmitter is bound to a "cage" molecule, and the cage releases the neurotransmitter in response to a particular frequency of light. See for a description. A fiber optic device might be controlled by wireless, and then used to uncage the transmitter which would activate the nanobots.

In any event, the constraint on a remote control would be that the added receiver should be small enough that the receiver plus nanobot still remain nanoscale. Plus which, you want to be sure that the device can't be activated accidentally or miss commands due to noise.

Hope this helps.
