A novel sandwich-type electrochemical multiplexed immunoassay was designed for simultaneous determination of alpha-fetoprotein (AFP) and carcinoembryonic antigen (CEA) cancer biomarkers by using bio-based polymer-nanotags as signal probes and dual antibodies labeled magnetic beads as capture probes. This signal probes were prepared by co-immobilizing encoded metallic apoferritin (Cd-Apo and Pb-Apo)...
Herein, we first report electrodeposition of dense (1.3×10 9 cm −2 ) and uniform (RSD of size is about 11%) Ag nanoflowers on ITO glass by a double-potentiostatic method without any surfactant. Raman spectra showed that the Ag nanoflowers with multiple petals on ITO glass exhibited excellent SER(R)S ability. It could accommodate a considerable range of sample concentrations (10 ...
