OK, so now you have lots of robots on the outside of the victim.
Now they just have to penetrate the skin, evade the immune system and
work their way to their targets in a timely way.

How fast can microbes move (since they are about the same size)?
Some useful numbers here:
http://book.bionumbers.org/how-fast-do-cells-move/

High of 1mm/sec, low of micrometres per hour...

Will the speed vary in different tissues?

What proportion are destroyed before they reach the target?

How many get lost (navigation errors)?

The dose required and the onset speed are going to be determined by
factors like these.
