摘要：
An autonomous nonenzymatic DNA machine has been successfully engineered based on a two-layered cascaded hybridization chain reaction (C-HCR) circuit, in which the tandem outputs of the upstream HCR-1 unit activate the downstream HCR-2 unit to induce successive repeated hybridizations, generating branched DNA structures and enabling sensitive and selective detection of uracil-DNA glycosylase and its inhibitors.
