摘要:

基于Cu-MOF導電材料，建立了Ru3+@Cu-MOF(-NH2)/Au界面的電化學原位組構方法，并對其電化學性能進行了全信息表征。以RuCl3為中心分子、2�舶被鶎Ρ蕉�甲酸為配體，采用電化學陽極合成法構建了Ru3+@Cu-MOF(-NH2)/Au界面，采用方波伏安法和循環伏安法分別考察了該界面對亞甲基藍（MB）的電化學響應性能。結果表明，該界面對MB的檢測限為4.2 pmol/L，線性范圍為10.0 pmol/L~100.0 nmol/L，證明了該界面對MB具有優異的電化學響應性能。將該界面應用于組構卡那霉素（Kan-A）電化學適體傳感器后，研究發現該傳感器對Kan-A的靈敏度為0.06，檢測限為12.3 pmol/L，線性范圍為10.0 pmol/L~100.0 nmol/L。且該傳感器能顯著區分盤尼西林（Pen-G）、四環素（TET）、阿莫西林（AMO）、磺胺對甲氧基嘧啶（SMZ）4種抗生素，展現出優異的電化學傳感性能，可用于實際體系中Kan�睞的定量檢測。

Abstract:

Based on Cu-MOF conductive materials, an in-situ electrochemical fabrication method for Ru3+@Cu-MOF(-NH2)/Au interface was established and its electrochemical properties were fully characterized. Utilizing RuCl3 as the central molecule and 2-aminoterephthalic acid as the ligand, the Ru3+@Cu�睲OF(-NH2)/Au was formed through electrochemical anodic synthesis. The electrochemical response performance of the interface to methylene blue (MB) was investigated by square wave voltammetry (SWV) and cyclic voltammetry (CV). The results show that the detection limit of the interface to MB is 4.2 pmol/L, and the linear range is 10.0 pmol/L~100.0 nmol/L, which proves that the interface has excellent electrochemical response performance to MB. After applying it to the electrochemical aptasensor for Kanamycin (Kan-A), it’s found that the sensitivity of the sensor to Kan-A is 0.06, the detection limit is 12.3 pmol/L, and the linear range is 10.0 pmol/L~100.0 nmol/L. The sensor can significantly distinguish the four antibiotics of penicillin (Pen-G), tetracycline (TET), amoxicillin (AMO) and sulfamethoxypyrimidine (SMZ), showing excellent electrochemical sensing performance and can be used for the quantitative detection of Kan-A in the actual system.
