1 μg/L. Using the portable custom analyzer, the detection time was shortened to 30 s with a tradeoff in the LOQ (1 μg/L). In both cases, the LOQs remain within the environmentally relevant PAE concentrations of 0.1-1472 μg/L.Herein a versatile photoelectrochemical (PEC) immunoassay platform for sensitive and specific screening of tumor biomarkers (carcinoembryonic antigen; CEA) was innovatively designed using hollow cadmium sulfide (H-CdS) as photoactive matrix based on immunomagnetic separation. Experimental results reveal that the h
