A quick and reproducible SERS-based immunoassay, using functionalized hollow gold nanospheres and magnetic beads, has been developed. Here, a simultaneous detection of dual cancer markers in blood serum has been achieved under a single excitation wavelength. The accuracy and sensitivity for clinical sera from five patients confirms their diagnostic feasibility.
