Label-free electrochemical IgE aptasensor based on covalent attachment of aptamer onto multiwalled carbon nanotubes/ionic liquid/chitosan nanocomposite modified electrode

A simple, sensitive and label-free aptamer-based biosensor for the detection of human immunoglobulin E (IgE) is developed using the electrochemical transduction method. A special immobilization interface consisting of multiwalled carbon nanotubes/ionic liquid/chitosan nanocomposite (MWCNTs/IL/Chit)...
