CONCENTRIC SQUARE-TYPE ABSORBER AND APPLICATION THEREOF IN PESTICIDE RESIDUE DETECTION

摘要

A concentric square-type absorber and application thereof in pesticide residue detection. The concentric square-type absorber is in an array structure formed by assembling several single concentric square-type absorbers. Each single concentric square-type absorber comprises a bottom layer (110) and a single concentric square-type structure (120) closely attached onto the upper surface of the bottom layer (110); the bottom layer (110) is made of high-resistance silicon, and has a square structure; the single concentric square-type structure (120) is made of gold, and consists of an inner square structure (121), an outer square structure (122), and two outer square arms (124). By using the concentric square-type absorber to detect pesticide residue, bottlenecks such as complicated data processing, rapid detection incapability, and low sensitivity of traditional pesticide residue detection methods are broken through. By using the concentric square-type absorber as a carrier, rapid nondestructive detection can be achieved, and the detection sensitivity is improved.
