Highly efficient photoelectrochemical biosensor for the evaluation of bisphenol A-induced microRNA-21 expression alterations
{{output}}
Herein, we developed a photoelectrochemical (PEC) biosensor integrating SrTiO3 and SnO2 materials with a dumbbell DNA mediated target recycling system to quantify microRNA-21 levels under bisphenol A (BPA) exposure. The engineered SrTiO3/SnO2 photoelectrode de... ...
