Abstract:
1. A glycated protein measurement sensor, comprising: first and second unit sensors, each comprising: wherein a ligand composite is disposed on a first sensing film of the first unit sensor, the ligand composite containing, as an active ingredient, aromatic boronic acid binding to a first target material, and a receptor is disposed on a second sensing film of the second unit sensor, the receptor binding to the first target material and a second target material, wherein the first and second sensing films are identically configured to include any one of carbon nanotubes and graphene, wherein the first target material is glycated human serum albumin (gHSA) and the second target material is human serum albumin (HSA), wherein when saliva is in contact with at least a portion of the first sensing film of the first unit sensor, the change in current flowing in the first sensing film is measured, the change being induced by the connection of the first sensing film with the gHSA in the saliva via the ligand composite containing the aromatic boronic acid as the active ingredient, and wherein when saliva is in contact with at least a portion of the second sensing film of the second unit sensor, the change in current flowing in the second sensing film is measured, the change being induced by the connection of the second sensing film with the gHSA and HSA in the saliva via the receptor.
