title: The effect of DNA aptamer configuration on the sensitivity of detection thrombin at surface by acoustic method.
abstract: Using an acoustic method we showed that the aptamer configuration, especially those comprised of dimers with binding exosites sensitive to heparin and fibrinogen at thrombin, substantially increases the aptasensor sensitivity.
