RSC Analytical Division Northern Ireland Local Section Lecture

6 December 2017 16:00-17:00, Belfast, United Kingdom

When we are well, how do we see? How do we doodle? When we are ill, how do medical professionals look after us? The partial answers to questions like these arise from molecular logic gates. The first of these arose in Belfast when we recognized the similarities between semiconductor logic gates and chemical reactions. Fluorescent YES gates can monitor sodium levels in blood within millimetre-sized channels. These serve society by operating in hospital intensive care units and ambulances, and are the basis of a half-billion-dollar industry. Other logic gate systems, akin to a full computer running a dedicated program, perform human-scale computations, e.g. edge detection of objects and outline drawing. More than 550 laboratories have contributed to this field so far. These nanometric gates can enter small inaccessible spaces, e.g. living cells, and send back raw or processed information.
