Your body, in many ways, is a computer. It’s not wired up with silicon, but relies on chemical pathways to transmit and receive information and instructions. Conventional electronics tend to not play well with biology, but the invention of the first artificial chemical circuit could be the key to interacting directly with our cells.
A chemical circuit is very similar to an electrical circuit: you’ve got signals that come in, logical functions are performed, and other signals go out. In an electrical circuit, you’ve got electrons doing all the signalling, with silicon transistors forming the logic framework inside the circuit itself. A chemical circuit uses charge-carrying molecules instead of electrons for signaling, and the transistors doing all the logic work are made of charged biomolecules.
