Electrochemical assay for attomole detection of DNA The project was carried out in collaboration between CDNA and DTI. We combined a magnetic bead sandwich hybridization capture assay used for pre-concentration and bioseparation of target DNA, with a lipase-based amplification and electrochemical readout system. The signal amplification in the DNA assay is based on the catalytic activity of a lipase enzyme, and this “electrochemical blotting” concept is principally new. The use of this hydrolytic enzyme allowed for close to few-molecule detection of lipase-labeled DNAs at the electrode surface, due to accumulation of the catalysis product (ester bond cleavage and removal of the redox label from the zone of electrochemical reaction). The developed electrochemical lipase- and magnetic beads-based sandwich hybridization assay represents a fundamentally new electrochemical approach for sensitive DNA detection. ChemComm link |

CDNA highlights
March 2, 2010
Single-molecule chemical reactions on DNA origami Researchers at the Danish National Research Foundation’s Centre for DNA Nanotechnology (CDNA) at iNANO demonstrate that it is possible to control chemical reactions on DNA nanostructures and generate images of reactions of individual molecules. The results were published on 28 February in Nature Nanotechnology. The article is available here |
