Method for detecting biomolecules using a capacitive touch screen

Abstract

There is provided a method of detecting biomolecules using a capacitive touch screen receiving a touch with a conductor as an input signal to perform an output on a display screen, and more particularly to a method of detecting target biomolecules by applying biomolecules having electrical conductivity to a touch panel and detecting a change in capacitance of a surface of a touch panel generated according to the concentration of the biomolecules. A method of detecting biomolecule according to the present invention uses a capacitive touch screen capable of being cheaply manufactured on a large scale, such that the method may have advantages such as cheap cost and a short analysis time and simply detect biomolecules in a personal terminal such as a smart phone, a tablet PC, and the like, on which a capacitive touch screen is mounted, as compared to the existing method requiring an expensive exclusive analysis apparatus based on absorbance or fluorescence having a large volume, a skilled experimental technique such as electrophoresis, or a long analysis time to thereby be performed only in an experimental room equipped with specialists and equipment
