Increased Anticoagulant Activity of Thrombin-binding DNA Aptamers by Nanoscale Organization on DNA Nanostructures

From The Clinical Editor: Thrombin inhibition via DNA aptamers has recently become a possibility. In this study, thrombin-binding DNA aptamers were further optimized by nanoscale organization on DNA nanostructures. The authors have created a novel, functional DNA nanostructure, which is a multi-aptamer inhibitor with activity eightfold higher than that of free aptamer. Reversal of thrombin inhibition was also achieved by single-stranded DNA antidotes, enabling significant control over the coagulation pathway.
