1 A novel signal "on" type of photoelectrochemical biosensor for microRNA-21 hybridization detection was fabricated, where Bi2S3 nanorods were used as photoactive material with a maximum adsorption at 450 nm visible light, hairpin-structure DNA as detecting probe, streptavidin as signal capturing unit and biotin functionalized ascorbic acid loaded apoferritin as signal amplification unit.
