Patent ID: 7764070

Claim:
A bio molecular detection apparatus, the apparatus comprising: a signal converting unit having at least one inductance device and at least one capacitance device connected with each other; a biochip disposed in the signal converting unit; an input port connected with one end of the signal converting unit, for receiving a signal for measuring an electrical characteristic of the signal converting unit; an output port connected with an other end of the signal converting unit, for outputting a signal from the signal converting unit; and a characteristic detecting unit connected with the output port, for measuring the electrical characteristic of the signal converting unit, the at least one inductance device covers a surface of a substrate, and comprises a spiral shaped microstrip formed on a surface of a layer having a lower dielectric constant than the substrate, the at least one capacitance device comprises two tandem electrodes formed apart from the inductance device on the surface of the layer having a lower dielectric constant at a predetermined distance so as to be opposite and interlocked to each other, and the at least one inductance device and the at least capacitance device are connected in series to each other.
