Research related to molecular logic gates is a fast growing and very active area and molecular devices have become the new frontier in computing. Researchers now have designed and synthesized ...

Importantly, the new biological logic gates are also modular, meaning they could be fitted together to make different types of logic gates and more complex biological processors.

DNA logic gates calculate square root using 130 different molecules A DNA-based computer uses simple base-pairing to create AND and OR logic gates … ...

Light-based logic: The optical chirality logic gate is made of a nonlinear optical material that generates an output signal that’s dependent on the chirality of the two input beams. (Courtesy: Yi ...

He also had some impractical logic gates that were very illustrative, even if they didn’t work very well. The first attempt fell somewhat short, but all problems were eventually resolved.

Towards ultrafast logic gates (Courtesy: University of Rochester illustration / Michael Osadciw) The first logic gate to operate at femtosecond timescales could help usher in an era of information ...

The new logic gates are formed from short strands of DNA and their complementary strands, which in conjunction with some simple molecular machinery mimic their electronic equivalent.

One of the "YES" gates they designed is a short peptide -- one of the constituent parts of cellular proteins. This peptide gate can be cleaved by an enzyme known as matrix metalloprotease (MMP).
