Self-checking dual-modal aptasensor based on hybrid Z-scheme heterostructure of Zn-defective CdS/ZnS for oxytetracycline detection

A novel dual-model photoelectrochemical/electrochemical sensor based on Z-scheme TiO2 disks/methylene blue for kanamycin detection

“…In order to improve the accuracy of quantitative analysis, dual-model sensors based on the conversion of two different signals have become a developing trend. 26–28 Since the two signal response mechanisms are completely independent, the dual-model sensor not only integrates the advantages of the two modes but also verifies the detection results mutually, reducing the impact of the uncertainty error of the single-mode sensor and improving the reliability of detection results. 29–31 Electrochemical (EC) sensors have attracted substantial attention because of their high sensitivity, simplicity, quick response, and low cost.…”
