覆盆子型铁钴纳米氧化物材料用于氧氟沙星和环丙沙星的无酶荧光检测
Fluorescent Sensor Constructed with Raspberry-shaped CoFe2O4 Nano Oxide for Enzyme-free Fluorescence Detection of Ofloxacin and Ciprofloxacin
摘要
Abstract
A novel raspberry shaped iron cobalt oxide nanomaterial(R-CoFe2O4-ONMs)was synthesized using a soft template method and direct water bath heating with the help of surfactant sodium dodecyl sulfate(SDS).We studied the ultra sensitive detection of ofloxacin(OFL)and cip-rofloxacin(CIP)in aqueous solutions using R-CoFe2O4-ONMs fluorescence detection.The results showed that the detection limits(LOD)for OFL and CIP antibiotics were 35.78 and 33.47 ng/mL,respectively.Study the effects of pH value,iron cobalt molar ratio,and initial material quality on the fluorescence detection performance of R-CoFe2O4-ONMs.At the same time,the quenching mechanism was also discussed,provi-ding factual basis for the subsequent fluorescence detection of antibiotics in other materials.R-CoFe2O4-ONMs,as a fluorescent sensor with good selectivity,anti-interference and cycling properties,are expected to have good application prospects in the detection of quinolone antibiotics.关键词
