The bimetallic nanoparticles of bismuth‐silver were used to modify a disk GCE for the simultaneous electrochemical analysis of caffeine (CAF), ascorbic acid (AA), and paracetamol (PAR). The constructed Bi‐AgNPs/GCE illustrated strong electrocatalytic activity towards the oxidation of CAF, PAR, and AA. Under the optimum conditions, the sensor provided linearity for PAR, AA, CAF between 2 to 20 μΜ, 10 to 70 μM, and 2 to 40 μM (n=3), respectively. The detection limits for CAF, PAR, and AA was 2.36 μM, 0.155 μM, and 0.697 μM, respectively. The GCE/Bi‐AgNPs sensor presented good sensitivity and selectivity for the simultaneous electrochemical analysis of CAF, PAR, and AA.

铋银纳米传感器同时检测扑热息痛，抗坏血酸和咖啡因

铋-银的双金属纳米颗粒用于修饰圆盘GCE，用于咖啡因（CAF），抗坏血酸（AA）和对乙酰氨基酚（PAR）的同时电化学分析。所构建的Bi-AgNPs / GCE对CAF，PAR和AA的氧化具有很强的电催化活性。在最佳条件下，该传感器为PAR，AA，CAF提供的线性分别在2至20μM，10至70μM和2至40μM之间（n = 3）。CAF，PAR和AA的检出限分别为2.36μM，0.155μM和0.697μM。GCE / Bi-AgNPs传感器对CAF，PAR和AA的同时电化学分析具有良好的灵敏度和选择性。
