Quantitative determination of uric acid using paper-based biosensor modified with graphene oxide and 5-amino-1,3,4-thiadiazole-2-thiol

Paper-based sustainable biosensors

“…ATT showed good selectivity for specific binding with uric acid and the interference from nitrites in human blood and blood fluids could be prevented in the CV analysis owing to their different oxidation potentials. 125 In another study, a robust, user-friendly, and portable smartphone-aided biomimetic metal-organic framework (MOF) nanoreactor colorimetric paper (SBMCP) device was fabricated for the…”

“…ATT showed good selectivity for specific binding with uric acid and the interference from nitrites in human blood and blood fluids could be prevented in the CV analysis owing to their different oxidation potentials. 125 In another study, a robust, user-friendly, and portable smartphone-aided biomimetic metal–organic framework (MOF) nanoreactor colorimetric paper (SBMCP) device was fabricated for the on-demand POC recognition of endogenous biomolecules. In this study, the single/multiple enzyme constituents trapped within the micropores network of ZIF-8 (exoskeleton) facilitated the sensitive and selective detection of the target analyte, and then relocated the detection event to a visual color signal based on the cascade effect.…”
