| 2 | Fabricating UCNPs-AuNPs Fluorescent Probe for Sensitive Sensing Thiamphenicol显示文摘A novel fluorescent probe has been constructed based on fluorescence resonance energy transfer(FRET)between upconversion nanomaterials(UCNPs)NaYF4:Yb,Er and gold nanoparticles(AuNPs).The fluorescent“off-on”switching was formed for the detection of thiamphenicol(TAP)in egg samples.The fluorescence of UCNPs can be quenched to a certain degree by AuNPs.After adding TAP,the AuNPs generated aggregation and the fluorescence of UCNPs was recovered.The synthesized amination UCNPs and AuNPs were characterized by Fourier transform infrared spectroscopy(FTIR),UV-Vis,X-ray diffraction(XRD),energy dispersive spectrometer(EDS),and transmission electron microscope(TEM)techniques for observation and confirmation.As a model target,the detection of TAP has two linear ranges in the buffer solution within 0.01–0.1µmol/L and 0.1–1µmol/L using this fluorescent probe.The detection limit was obtained to be 0.003µmol/L(S/N=3),which is favorable for trace analysis.The recovery of TAP from 98.2%to 105.3%was obtained,and the relative standard deviation(RSD)was from 2.5%to 4.3%.Furthermore,the method established in this study based on the UCNPs auto-low background fluorescence has high selectivity and strong ability to eliminate interference,which is beneficial to analyzing complex samples. | YI Jiaqi LI Xiaoshuang CUI Di HAN Lixia JIANG Wei ZHANG Renguo NIU Na CHEN Ligang | 2022 | Chemical Research in Chinese Universities2022，38，6： | 0 |
