Detecting heparin : We report a new fluorescent approach to the detection and quantification of the biologically relevant molecule heparin. We designed and prepared a cyclic peptide that is able to catalyse the hydrolysis of a fluorogenic anionic ester (green) under low‐concentration conditions. Then we demonstrated that the inhibition of this artificial enzyme (grey) by heparin (red) allows its fluorescent sensing with a remarkable sensitivity of 13 n M .
