We develop a quantum dot based DNA nanosensor specifically targeting the cleavage-religation activity of an essential DNA-modifying enzyme, human topoisomerase I. The assay has shown great promise in biological crude samples and thus is expected to contribute to clinical diagnostics and anti-cancer therapy.
