Controllable sensitization of Zr-MOFs by CdS and its application for photoelectrochemical detection of alkaline phosphatase Ying Ying , Wenying Wu, Guihua He, Wenfang Deng, Yueming Tan and Qingji Xie Abstract CdS quantum dots (QDs) are attached on zirconium-based metal-organic frameworks (Zr-MOFs) with DNA as a bridge to boost the photoelectrochemical (PEC) activity of Zr-MOFs, and the sensitization of Zr-MOFs by CdS QDs is regulated by alkaline phosphatase (ALP)-catalyzed hydrolysis of...
