Biosensors for detecting Homocysteine and Cysteine

摘要

The present invention relates to a biosensor exhibiting high selectivity for homocysteine (HCys) or cysteine (Cys) and showing excellent results in terms of detection limit, reliability and stability. In particular, the present invention finds that it is possible to distinguish homocysteine (HCys) and cysteine (Cys) having similar structures containing a thiol group by selection of a molecular imprinting polymer (MIP) Providing a means capable of detecting with selectivity. Thus, the present invention can be used to detect HCys and Cys, which are known to be carriers of various diseases.
