more complex systems, such as brain neurons. Tour and colleagues’ work provides a host of opportunities for the development of further chemical tools. A wish list for next-generation designs might include calcium-responsive groups with brighter fluorescence and more rapid turn-on responses; ratiometric readouts of fluorescence that allow the concentration of ions in nano metre-sized calcium bursts to be measured; and a choice of coloured reporters, so that different kinds of sensor can be used… CONTINUE READING
