Washburn et al. [87] described the simultaneous detection of eight cancer biomarkers (alpha fetoprotein (AFP), activated leukocyte cell adhesion molecule (ALCAM), cancer antigen 15-3 (CA15-3), cancer antigen 19-9 (CA19-9), cancer antigen 125 (CA-125), carcinoembryonic antigen (CEA), osteopontin, and prostate-specific antigen (PSA)) in serum using an antibody-based sandwich assay, in 1 h, based on silicon photonic biosensors. This evidence concerns the gene MUC16 and cancer.
