Abstract
Gold-doped carbon dots (CDAu) were simply and quickly prepared via microwave procedure using fullerene as a precursor, a rapid detection method for chlorpyrifos was established using surface enhanced Raman scattering (SERS) combined with aptamer (Apt) controlled gold-doped carbon dots catalytic reaction. As the result, the SERS intensity decreased due to the aptamer inhibited the CDAu catalytic reduction of chlorauric acid by glucose. However, in the presence of chlorpyrifos, SERS intensity increased linearly with the concentration of chlorpyrifos in the range of 12.8–432.8 ng/L, the correlation coefficient was R2 = 0.9961.
