Our news editors obtained a quote from the research, "This paper demonstrates that utilizing a bioconjugate of gold nanoparticles and enzyme-labeled antibody as a signal probe increases the sensitivity of a traditional ELISA for 7-ANZP by nearly 20 times. The sensitivity of this ELISA for 7-ANZP was 5.6 pg/mL in buffer, and the limit of detection (LOD) of 0.18 g/kg for 7-ANZP in urine could be achieved after the urine samples were simply hydrolyzed and diluted by buffer."
According to the news editors, the research concluded: "This simple and sensitive method has potential application for improving the sensitivity of ELISA methods against various small molecules."
