Molybdenum blue mediated photothermal immunoassay for CEA detection based on Ag 4 P 2 O 7 @Ag nanocomposites
A photothermal immunoassay was built for tumor marker detection based on Ag P O @Ag nanocomposites. Ag P O @Ag nanomaterials were synthesized by precipitation-photoreduction reaction, and characterized by transmission electron microscope (TEM), scanning electron microscopy (SEM), atomic force micros...

@Ag under acidic conditions react with ammonium molybdate in the action of reductant generating molybdenum blue. The photothermal change is due to molybdenum blue solution depending on the concentration of carcinoembryonic antigen (CEA) in immunoassay. Under optimal conditions, there is a linear relation between ΔT and CEA concentration in the range of 1 pg mL
-40 ng mL
with the detection limit of 0.33 pg mL
. Meanwhile, the developed photothermal immunoassay displays preferable selectivity, repeatability, and stability. |
