A simple and rapid optical biosensor for detection of aflatoxin B1 based on competitive dispersion of gold nanorods.

This report illustrates a promising one-step and label-free optical biosensor for determination of aflatoxin B1 (AFB1) that is most commonly found in foods and highly dangerous even at very low concentrations. In this research, gold nanorods (GNRs) were employed as a sensing platform, which showed high stability under high ionic strength conditions without… CONTINUE READING
