From solutions to living systems: a colorimetric and “turn-on” chemosensor for Co2+ with paper-strip and bioimaging applications

5-(4-Chlorophenoxy)-3-methyl-1-phenyl-1H-pyrazole-4-carbaldehyde (PYA), a pyrazole-based fluorescent chemosensor, was synthesised and studied for the selective detection of Co2+ ions. With exceptional selectivity over other metal ions that are relevant to biology and the environment, the sensor displays a clear “turn-o...
