Scientists at The Scripps Research Institute in California and the Technion — Israel Institute of Technology — have developed a “biological computer” made entirely from biomolecules that is capable of deciphering images encrypted on DNA chips.
This is the first experimental demonstration of a molecular cryptosystem for images based on DNA computing.
When suitable software was applied to the biological computer, it could decrypt, separately, fluorescent images of The Scripps Research Institute and Technion logos.
The hardware and software in these devices, Keinan notes, are complex biological molecules that activate one another to carry out some predetermined chemical work. The input is a molecule that undergoes specific, predetermined changes, following a specific set of rules (software), and the output of this chemical computation process is another well-defined molecule.
