Abstract

Pollution of the environment by heavy metal species is a worldwide problem on account of their toxicity. Instrumental analysis, which is time-consuming and expensive, is generally used for the heavy metal analysis. Simple and rapid analysis method is useful for screening the pollution. We developed highly sensitive cadmium immunoassay based on kinetic exclusion assay in a microchip. The microfluidic immunoassay was completed within 7 min. The lower detection limit for cadmium was 1.85×102 ng/L, which satisfied much stricter regulation in Japan.
