Carcinoembryonic antigen (CEA) is regarded as one of the crucial tumor markers for colorectal cancer. In this study, we developed the snowflake Cu<sub>2</sub>S/Pd/CuO nanocomposite to construct an original label-free electrochemical immunosensor for the ultrasensitive detection of CEA levels. The nanocomposite of cuprous sulfide (Cu<sub>2</sub>S) with Pd nanoparticles (Pd NPs) was synthesized through an <i>in situ</i> formation of Pd NPs on the Cu<sub>2</sub>S. Cuprous sulfide (Cu<sub>2</sub>S) ...[more]
