What do medicine and assassins have in common?  Self-Destructing electronics of course!  In a breakthrough that will surely revolutionize delivery methods for medicine, perhaps even microsurgery, a group of scientists have created electronics that actually break down and degrade after performing their tasks.

nanitesFrom a medical perspective the possibilities for this technology are limitless.  Imagine being able to program a tiny robot to navigate through a patient’s body, find a specific spot, and administer medicine directly where it is needed.  What about microsurgery?  Could doctors program small surgical microbots to repair delicate blood vessels?  Could these microbots remove clots hidden deep within sensitive areas?  Could we use these them to “scrub” parts of the body that accumulate buildup over time, such as plaque in arteries, or even tar in lungs?  What about searching out and directly targeting cancer cells?  Could medical microbots be used to hunt down viruses like itsy-bitsy terminators, and then simply melt away after having completed their task? 
Of course with all the possible uses I can think of to benefit humanity there’s at least one negative.  This technology could make it so much easier to assassinate people and leave absolutely no trace behind.  Combining this technology with that of small flying robotics, such as hummingbird or insect-sized drones, its conceivable that eliminating targets could simply come down to sending a bug-sized robot off to find the target and deploy a degradable microbot to deliver the killing blow?  Imagine a tiny fly buzzing over a glass of water and dropping its payload of microscopic killers before flying away.  It could be anything from poison, to something designed to sever an artery or damage the heart, or rupture a blood vessel in the brain.
