DNA Computers
From Mainframes and Super-computers that NASA and the military used to perform on large volume of data to hand-held gadgets like your palmtop, now come the latest in nanocomputers- super small computers made of DNA, also known as Biomolecular computers! So small that a trillion fit in a drop of water!
It was developed by a team of three from Weizmann Institute’s Biological Chemistry and Computer Science and Applied Mathematics Departments. The first version was developed in 2001 to do simple computations of 0s and 1s.
A newer version of the device, created in 2004, detected cancer in a test tube and released a molecule to destroy it. A sort of ‘doctor in a cell’ locating disease and preventing its spread – biomolecular computers could possibly be injected into the human cells and conceived to perform millions of calculations in parallel. Now, team in a paper published online August 3 in Nature Nanotechnology, have devised an advanced program for biomolecular computers that enables them to ‘think’ logically.
