Abstract:
We report an easy and efficient approach based on a target-induced molecular-switch on triple-helix DNA (THD)-functionalized carbon nanotubes (CNTs) for the simultaneous visual detection of nucleic acids and proteins with a lateral flow nucleic acid biosensor. The assay had the capability to detect a minimum of 25 pM target DNA and 0.25 nM thrombin simultaneously within 20 min.
