A STUDY ON THE USE OF CARBON QUANTUM DOTS ON hCG IMMUNE ANALYSIS

Abstract

Quantum dot – antibody conjugations are of potential materials for diverse bioanalysis, diagnosis and medical treatment applications. Herein, we present the synthesis of human chorionic gonadotropin (hCG) – carbon quantum dot (CQD) conjugate and its application in immune analysis of hCG antigen. By comparing with the standard analysis procedure, it has been revealed that hCG-CQD conjugation can be used for the analysis of hCG antigen with a detection limit of about ng/ml.
