A sensing platform is presented for the determination of alkaline phosphatase (ALP) activity based on the cooperation of DNAzyme-Au spherical nucleic acid nanoprobe with the graphene-oxide-loaded hybridization chain reaction (HCR/GO) system to achieve good detection sensitivity and specificity. This assay takes advantage of the strong affinity of pyrophosphate (PPi) to Cu2+ ions and the fact that ALP can hydrolyze pyrophosphate (PPi) to release free Cu2+ ions. In the presence of ALP, the released Cu2+ can promote the Cu2+-depende
