Fluorescent carbon dots and hydrogels thereof and applications, and enrofloxacin detection method

Abstract

This invention belongs to the field of fluorescent carbon nanomaterial preparation and antibiotic detection technology, disclosing fluorescent carbon dots and their hydrogels and applications, as well as a method for detecting enrofloxacin. A fluorescent carbon dot hydrogel was constructed based on fluorescent carbon dots, and an enrofloxacin detection method was constructed based on fluorescent carbon dots or the fluorescent carbon dot hydrogel. The detection method involves mixing fluorescent carbon dots with the sample to be tested, according to... 411 / I 508 Enrofloxacin quantification is achieved by fitting the value of the G / B ratio to the enrofloxacin concentration; alternatively, the fluorescent carbon dot hydrogel is immersed in the sample and incubated for a sufficient time, and a colorimetric image is obtained under 365 nm ultraviolet light. The G / B value of the fluorescent carbon dot hydrogel region in the colorimetric image is obtained, and the quantitative analysis of enrofloxacin is achieved based on the fitting relationship between the G / B value and the enrofloxacin concentration. This invention can improve the accuracy of enrofloxacin detection and, furthermore, enable rapid and high-throughput detection of enrofloxacin.
