Liquid computer

The computer you are sitting at right now does its 'thinking' in a load of tiny silicon switches called logic gates. This Chemistry World article explains how liquids in tiny channels can do the same job and process chemical, not electronic data.

Computing goes into solution

15 November 2007

South Korean scientists have developed the first soluble molecular logic gates - one step along the way to designing molecular computers and biological lab-on-a-chip devices. A team of scientists led by Juyoung Yoon of Ewha Womans University has used solutions of fluorescent sensor molecules that respond to 'inputs' of pH, metal ions and, for the first time in a molecular logic gate, proteins.
