title: Ultrasensitive protein detection using an aptamer-functionalized single polyaniline nanowire.
abstract: A highly sensitive, conductometric and label-free biosensor for the detection of immunoglobulin E (IgE) is developed based on the immobilzation of the IgE aptamer onto a single polyaniline nanowire electrochemically synthesized in a facile and controllable way.
