Wissenschaftler haben Logic Gates (AND, OR, NOT etc, die Grundbausteine von Prozessoren) mit Nano-Bots (DNA-Stränge, die auf bestimmte Proteine reagieren) in einer Kakerlake nachgebaut und arbeiten nun daran, das ganze zu einem 8-Bit-DNA-Biorechner hochzuskalieren, der einem C64 gleicht. RUN, COCKROACH! RUN!
The Team […] injected various kinds of nanobots into cockroaches. Because the nanobots are labelled with fluorescent markers, the researchers can follow them and analyse how different robot combinations affect where substances are delivered. The team says the accuracy of delivery and control of the nanobots is equivalent to a computer system. "This is the first time that biological therapy has been able to match how a computer processor works," says co-author Ido Bachelet of the Institute of Nanotechnology and Advanced Materials at Bar Ilan University.

The number of nanobots in the study – more than in previous experiments – makes it particularly promising, says Bachelet. "The higher the number of robots present, the more complex the decisions and actions that can be achieved. If you reach a certain threshold of capability, you can perform any kind of computation. In this case, we have gone past that threshold," he says.
The team says it should be possible to scale up the computing power in the cockroach to that of an 8-bit computer, equivalent to a Commodore 64 or Atari 800 from the 1980s. Goni-Moreno agrees that this is feasible. "The mechanism seems easy to scale up so the complexity of the computations will soon become higher," he says.
