Coumarin–DPA–Cu(ii) as a chemosensing ensemble towards histidine determination in urine and serum†
Abstract
An ensemble-based fluorescent sensor HS-1 + Cu2+ for detection of histidine is reported. Complex HS-1 + Cu2+ sensitively senses histidine at pH 7.4 in aqueous media. The quantitative determination of histidine in urine and fetal calf serum is also conducted.
