Photo-thermal lateral flow analysis device for simultaneously detecting resistance genes of various sulfonamide antibiotics and application of photo-thermal lateral flow analysis device

The invention discloses a photo-thermal lateral flow analysis device for simultaneously detecting multiple sulfonamide antibiotic resistance genes and application. The device comprises a test strip, n photo-thermal capture probes, a surface laser light source and a thermal detection device, n to-be-detected resistance gene capture sequences and quality control probe complementary sequences are respectively adsorbed on the surface of the Fe3O4-PDA-Au composite material to prepare n photo-thermal capture probes, wherein n is greater than or equal to 2; n to-be-detected resistance gene detection probes are sequentially fixed on the n detection regions on the test strip, and quality control probes are fixed on the quality control region. The method comprises the following steps: mixing n photo-thermal capture probes, a to-be-detected sample solution and a buffer solution, inserting the sample pad end of a test strip into the mixed solution for chromatography, irradiating the whole detection ...
