Fluorescent Sensing and Logic Systems

One of the main principles underlying luminescent sensors is based on PET (photoinduced electron transfer), according to which a switching ‘on’ of luminescence in response to chemical analytes can be designed. Since its generalization in Colombo, Sri Lanka, it has now grown to involve over 300 laboratories around the world [1]. Some of these sensor systems are serving in critical care units in hospitals and in ambulances, performing blood diagnostics [2]. Others visualize intracellular players. Yet others map species distributions in nanometric spaces near membranes. These spaces are too small for the tiniest silicon-based electronic devices to enter. Our introduction of molecular logic gates [1] from Belfast, Northern Ireland, allows us to build more complex sensor systems which can take data from several sensory channels and
process the data to give a single ‘go/no-go’ decision. More and more complex logic operations and even human-scale computations, e.g. edge detection of objects [3], are now achieved by molecular logic systems. Others allow molecular computational identification (MCID) of nano/micrometric objects [1], which is the first of such applications which addresses a problem that does not currently have solutions from semiconductor computing technology.
