Molecular logic-based computation and fluorescent sensors: The story so far

The path to molecular logic-based computation began in Colombo, Sri Lanka and proceeded to Belfast, Northern Ireland. From there it spread to many cities around the world when over 1260 laboratories contributed examples and ideas to advance the field (Figure 1A-C). The formative experiments and some future directions are mapped out in this perspective. Principles discovered here should have a bearing on the computing performed continuously by molecule-based living things to survive and prosper. The more mature field of fluorescent sensors served as the springboard for molecular logic, and still serves a continuing need in society for monitoring atomic and molecular species in various situations for improving health, environment and economy.
