Description
Summary:[Display omitted] •In-situ developed silver orthophosphate based binary composite for efficient detection of nanomolar levels of tetracycline.•High stability, reproducibility and enhanced specificity promised the sensor for industrial applications.•Detection of tetracycline in spiked milk samples with >95% efficiency. Silver phosphate based binary composite was successfully developed for the precise and rapid sensing of the antibiotic tetracycline (TC). The in-situ developed zirconium ferrate doped silver phosphate sensor possesses perceptible stability and reproducibility promising a better sensing platform. The ultrasensitive sensor exhibits a pronounced limit of detection of 6.38 nM and an accountable linear range of 10–90 nM. The developed sensor could detect more than 95% of tetracycline in the spiked milk samples.
