Micro PCR device, method of amplifying nucleic acid and method of measuring concentration of PCR product using the same

A micro PCR device comprising

• an amplification chamber, the amplification chamber having an inner surface coated only with a polycationic polymer;
• at least a pair of electrodes including a first electrode attached to a first inner surface and a second electrode attached to a second inner surface, wherein the first inner surface and the second inner surface face each other and the electrodes face each other to generate an electric field between the electrodes;
• and
• a detector for detecting an electrical signal generated from a PCR solution, wherein the detector is electrically connected to the electrodes,
• wherein the first electrode and the second electrode are coated with the polycationic polymer.
