موضوع به انگلیسی:Detection of sparfloxacin based on water-soluble CuInS2 quantum dots
بخشی از متن:Thioglycolic acid-modified CuInS2 quantumdotswere prepared by a hydrothermalmethod. A method for the determination
of sparfloxacin by a CuInS2 ternary-quantum dot fluorescence probe was established based on the
fact that the fluorescence of CuInS2 quantum dots can be significantly quenched by sparfloxacin. The optimized
experimental conditions are as follows: (1) the concentration of CuInS2 quantumdots is 0.4 mol·L−1; (2) the pH
of the buffer solution is 6, and 1 mL of buffer was used; (3) the reaction time is 5 min. The concentration of
sparfloxacin is linearly related to the fluorescence quenching intensity from 0.5 μg/mL to 1mg/mL, and themaximum
detection limit is 1 mg/mL.
