Soon scientists will have scaled down robotic insects. This is a good thing and most of this technology is being funded for Department of Defense uses as they will have a killer application there indeed. Miniature replica type bugs can go and collect DNA samples of the enemy, inject them with a sleeping type virus so they lose their will to fight or even get out of bed for that matter for a few days, thus your enemy is rendered useless without their will to fight.

But such Mosquito type Mechanical Electrical Mechanisms will also be able to go into an area where there is an E-Bola breakout, or Bird Flu and take samples to see which strain it is and report back with the collected blood samples along with DNA for those in the lab to engineer a response to the disease, virus, pathogen or bacteria.
