摘要：

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 mu M, 10 to 70 mu M, and 2 to 40 mu M (n=3), respectively. The detection limits for CAF, PAR, and AA was 2.36 mu M, 0.155 mu M, and 0.697 mu M, respectively. The GCE/Bi-AgNPs sensor presented good sensitivity and selectivity for the simultaneous electrochemical analysis of CAF, PAR, and AA.
