Disclosed is a biosensor. The biosensor comprises: an electrode; and a polymer structure disposed on the electrode and formed of poly-5,2':5′,2″-terthiophene-3′-carboxylic acid (pTTCA), wherein an enzyme is present in a state of covalently binding with pTTCA inside the polymer structure.

Biosensor and manufacturing method therefor

A polymeric film composition and a non-enzymatic glucose sensor including the functional polymeric film are provided. The polymeric film composition includes polyurethane and perfluorosulfonic acid polymer.

Polymeric film composition for non-enzymatic glucose sensor and non-enzymatic glucose sensor including the same

A new ferrous complex capable of being used as an electron transfer mediator for a glucose sensor, a biosensor, and the like, is provided, which measure a glucose concentration in blood, in which the new ferrous complex exchanges rapidly and smoothly an electron between an enzyme and electrode, is strongly absorbed into electrode, and is stable, so that the new ferrous complex allows excellent sensitivity of a glucose sensor to be maintained.

Electron transfer mediators for enzyme-based biosensor

A novel terthiophene-3-carboxylic acid compound is disclosed that a functionalized conductive terthiophene polymer having carboxylic groups produced in an electrochemical method using the compound as a monomer and a novel process for detecting DNA hybridization through impedance measurement using the polymer. In addition, a method for manufacturing a probe DNA used in the process for detecting DNA hybridization is provided. Since the process can detect DNA hybridization using impedance change, without the use of any indicator, small-sized sensor systems which measure impedance in a particular frequency range can be fabricated. The systems are applicable to portable sensors for identifying DNA sequence hybridization for clinical examination and disease diagnosis. Further, the process has an excellent selectivity of complementary sequences to mismatched sequences.
