Co₉S₈ nanoparticle-functionalized CdS nanoflowers for signal-off photoelectrochemical bioanalysis of carcinoembryonic antigens with hybridization chain reaction

Abstract

In this study, a signal-off photoelectrochemical aptasensing approach was designed for quantitative screening of carcinoembryonic antigen (CEA) by using cobalt sulfide nanoparticles-functionalized cadmium sulfide nanoflower (Co9S8@CdS) as photoactive matrix and...
