A Biosensor for Diagnosis of Myocardial Infarction Using Electrochemical And Localized Surface Plasmon Resonance Dual-Detection Method And A Diagnostic Method Using The Same

摘要

The present disclosure relates to a substrate unit capable of transmitting visible light and ultraviolet light and transmitting electricity; Nanoparticles in which nanoparticles are deposited on the substrate; and a binding portion comprising a plurality of multifunctional DNA structures including a three-way junction that binds to the nanoparticle portion and specifically binds to myocardial troponin I (cTnI); Myocardial infarction, characterized in that when the multifunctional DNA construct is combined with the myocardial troponin I (CTnI), the optical properties according to electrical impedance and local surface plasmon resonance (LSPR) are changed. It relates to a biosensor for diagnosis and a diagnosis method therefor.
