Molecular Computer

A computer based on logic gates that is constructed on principles of molecular mechanics (as opposed to principles of electronics) by appropriate arrangements of molecules. Since the size of each logic gate (device that can perform a logical operation) is only one or a few molecules, the resultant computer can be microscopic in size. Limitations on molecular computers arise only from the physics of atoms. Molecular computers can be massively parallel by having computations performed by trillions of molecules simultaneously. Molecular computers have been demonstrated using the DNA molecule.
