Human health is being menaced by numerous toxic chemicals. Agrichemicals are essential to farm, store and circulate agri-products, though they are highly toxicoids, even the slightest amount, which has lots of different kinds of constituents. Many analytical methods were studied for the detection only one or two kind of pesticides. However, the other types and thousands of agrichemical detection are yet unsatisfactory. Thus, a novel method is needed to detect lots of agrichemicals by a simple and sensitive system. CdTe quantum dots (QDs) were used to sense them by using a fluorescent spectroscopic tool. In this study, measurement of residual agrichemical residues in food was performed using surface-improved CdTe QDs with cysteamine. As a result, this novel method was able to detect many different kinds of agrichemicals at ppb level within only 10 min. Furthermore, we expect a possibility of sensing another type of agrichemicals.
