Chemical Nanocomputer
In general terms a chemical computer is one that processes information in by making and breaking chemical bonds and it stores logic states or information in the resulting chemical (i.e., molecular) structures. In a chemical nanocomputer computing is based on chemical reactions (bond breaking and forming) and the inputs are encoded in the molecular structure of the reactants and outputs can be extracted from the structure of the products meaning that in these computers the interaction between different chemicals and their structures is used to store and process information.
These computing operations would be performed selectively among molecules taken just a few at a time in volumes only a few nanometers on a side so, in order to create a chemical nanocomputer, engineers need to be able to control individual atoms and molecules so that these atoms and molecules can be made to perform controllable calculations and data storage tasks. The development of a true chemical nanocomputer will likely proceed along lines similar to genetic engineering.
