<p>PURPOSE: A glycoprotein measuring sensor and a portable glycoprotein measuring device are provided to simply measure a glycoprotein value by contacting the saliva to the measuring device without a blood collecting process. CONSTITUTION: A glycoprotein measuring sensor includes sensing films, a first unit sensor (10'), and a second unit sensor (10''). The first and second unit sensors include positive electrodes (400,400',400") and negative electrodes (500,500',500") which are formed on both end portions of the sensing films to be faced each other and spaced from each other at a predetermined distance. A ligand composition including an aromatic boronic acid joined with a first target material as an active component is arranged on a first sensing film of the first unit sensor. A receptor joined with the first target material and a second target material is arranged on a second sensing film of the second unit sensor. The first and second sensing films include one between a carbon nanotube and graphene and are identically comprised. The first target material is glycated human serum albumin (gHSA), and the second target material is human serum albumin (HSA). When the saliva is in contact with a predetermined portion of the first sensing film of the first unit senor, the first sensing film interposes the ligand composition so that a change in a current flowing in the first sensing film is measured. The current change is caused by the connection of the ligand composition and the glycated human serum albumin contained inside the saliva.</p> |
