Silver phosphate based flower-like MoS2/BiFeO3 nanocomposite with enhanced activity for the detection of tetracycline

Silver orthophosphate doped with flower-like MoS2/BiFeO3 binary composite was developed for the augmented and precise sensing of the antibiotic tetracycline. The in-situ developed silver orthophosphate modified composite showed excellent electrocatalytic activity due to its low resistance which favoured the redox probe mechanism. The limit of detection and the linear range of the composite were found as 4.57 pM and 10–90 pM corroborating the pronounced sensing capacity. The practical application of the sensor was analyzed with liquid milk samples spiked with tetracycline. More than 97% of tetracycline was detected which established its high demand in the analytical industry.
