中文摘要	herein, highly efficient solid-state ecl sensor was introduced for the first time onto the screen printed electrodes of the paper-based chips (pcs) based on the composite film of poly(sodium 4-styrenesulfonate) functionalized graphene (pssg) and nafion. attributed to the cooperative characteristics of both pss and graphene, pssg ensured both effective ru(bpy)(3)(2+) immobilization and fast electron transfer of ru(bpy)(3)(2+) in the composite film. the ecl behaviors at the developed sensor were investigated using tripropylamine as a representative analyte and low detection limit (s n-1 =3) of 5.0 nm was obtained. it also exhibited more excellent reproducibility (relative standard deviations of 0.63% for continuous 45 cycles) and long-term stability (similar to 80% of its initial ecl intensity could be retained over 3 months). more importantly, assisted by the developed ecl sensor, discrimination of 1.0 nm single-nucleotide mismatch in human urine matrix could be realized on the pcs for the first attempt. thus, the developed sensor was confirmed with the advantages of highly sensitivity, long-term stability, simplicity, low cost, disposability, high efficiency and potential applicability.
