Research on a molecularly imprinted electrochemical sensor based on a graphene quantum dot-gold nanoparticle composite for the determination of 17β-estradiol

In this study, a molecularly imprinted electrochemical sensor (MIECS) was constructed based on the combination of graphene quantum dots-gold nanoparticles (GQDs-AuNPs), molecular imprinting polymer (MIP), and electrochemical technology for the ultra-sensitive detection of 17β-estradiol (E
