Nanorobots Injected Inside Cockroaches
April 18, 2014 | Posted by Alain
A team of scientists from the the Institute of Nanotechnology and Advanced Materials at Israel’s Bar-Ilan University has constructed minute robots that can function inside a living animal entity. The nanobots act upon chemical stimuli inside the body; that is, upon receiving a chemical signal, they react, displaying appropriate responses. The robots were made by using DNA. The DNA was packed together into strands, and this is what make up the robots. Upon stimulated by chemicals, the robots would then unravel into the two strands of DNA. The DNA binds and unbinds in different circumstances, and this is the basis of the way the robots operate to be stimulated and to react.
They work at the cellular level, and that is where their extremely small size helps enormously. They might be tiny, but their tininess is what confers on them their herculean potential to tackle tumors and repairing broken tissues. Moreover, the nanobots can act as real computers inside the body. Therefore, they can be programmed to do a certain list of jobs which their makers choose for them.
The cobaye used to test the nanorobots were cockroaches. They – those terribly annoying creatures – could at least be rendered useful, right?! The cockroach species Blaberus discoidalis was used for the insertion of the nanorobots. The robots were crammed with chemicals, which, upon recognising hemolymph cells found in the cockroach, would bind to them. Hemolymph cells are, in fact, the equivalent of white blood cells in the cockroach. Different kinds of robots were made to enter the body of the unsuspecting cockroach.
The next step now would be to use other animals as cobayes before actually marketing these nanorobots in medical institutions for humans.
