Zusammenfassung:The present application proposes a method for detecting an okadaic acid based on a near-infrared photoelectric composite material, which includes the following steps: synthesizing NaYF4: Yb, Tm up-conversion nanoparticles (UCNPs) and a semiconductor material flower-like tungsten oxide (WO3) by a simple high-temperature solvothermal method; coupling the UCNPs with an okadaic acid monoclonal antibody through a classic amidation reaction to construct a competitive near-infrared photoelectrochemical immunosorbent assay (cNIR-PECIA) for okadaic acid detection. In addition, the present application employs a screen-printed carbon electrode (SPE) as the working electrode, and thus only requires a small amount of electrolytes, which is low-cost and maintenance-free.
