Aldehyde-Functionalized Eu(III) Helicate for l -Cysteine-Specific CPL Detection through Cyclization-Induced M-Helix Excess
l-Cysteine (Cys) levels are linked to many health issues and serve as critical diagnostic criteria for various diseases. However, their highly specific recognition and determination from complex biological matrices remain challenging due to interference from biothiol-containing analogs, such as homocysteine (Hcy) and...
