A photoelectrochemical sensor for detection of 17β-estradiol using high-response type II heterojunction: Implementation of visualization strategy

17β-estradiol biosensors based on different bioreceptors and their applications

“…Moreover, metal oxides and sulfides are combined, using the heterojunction between them to effectively separate the photogenic charge. For example, Wu et al (2023) developed a portable biosensor based on PEC, which could visualize real-time monitoring E2. The probe of this biosensor was modified with BiOBr/Ag 2 S. The LOD was 0.18 pM.…”
