Logic lies at the heart of modern computers, and the components that carry out its operations are logic gates. On the basis of a number of digital inputs (the presence or absence of some condition conventionally represented as 1's or 0's), a logic gate produces a single digital output. For example, a simple AND gate produces a 1 output when both of its inputs are 1, and a 0 output if either or both inputs are 0. In electronic computers, logic gates are sculpted on the surface of silicon wafers. Their inputs and outputs are electrical voltages, but these are not the only systems that can form logic circuits. Writing in Angewandte Chemie, Gupta and van der Boom describe a series of redox-active molecules anchored on glass surfaces that function as chemical logic gates.
