Abstract: A biosensor, for use in measurement of an analyte, includes a microporous membrane support, a first electrode system, a second electrode system, and a pair of insulating films. The first electrode system is formed on the surface of the microporous membrane support and the second electrode system is formed on the opposite surface of the microporous membrane support. The biosensor enables a rapid, simple, separation-free, and selective detection of the analytes. The biosensor does not require any bulky additional electrode, so that miniaturization, point-of-car testing, and disposability can be achieved.

Abstract: The present invention relates to an apparatus for maintaining freshness by applying a displacement current. Application of the displacement current to an object of preservation interrupts an ion channel of a living microorganism present in the object of preservation, thereby preventing the microorganism from proliferating and subsequently maintaining the freshness of the object of preservation. The apparatus for maintaining freshness by applying a displacement current includes: a displacement current control unit which regulates the displacement current at less than 1 A and less than 3 GHz; and a displacement current applying unit, comprising a first electrode, and a second electrode which faces the first electrode.

Abstract: A biosensor measuring an analyte contained in a sample is provided, including: an insulative lower substrate that has at least one electrode on which an enzyme reaction layer reacting with the analyte is formed; an upper substrate that faces the lower substrate and is made of a conductive material; and an adhesive layer that has a sample feed with a predetermined height on the enzyme reaction layer and attaches the upper and lower substrates to each other, where an end of the upper substrate acts as an electrode in which an electron-transfer mediator contained in the enzyme reaction layer is oxidized or reduced, and the other end acts as an electrical contact part that electrically contacts a measurement unit.

Abstract: A refrigeration and freezing control system and method thereof, which stores an object for preservation without quality deterioration for a long period, and which controls a supercooling or maintains freshness by controlling a frequency range. The refrigeration and freezing control system includes an electrode module having an anode and a cathode which faces the anode, and an electric field applying module which applies a voltage to the anode and the cathode, which generates an electric field having at least two frequency ranges between the anode and the cathode, and controls a frequency range of the applied voltage.

Abstract: A preserving apparatus has a multiple surface electrode structure that can keep an object disposed in a preserving apparatus fresh by disrupting an electrochemical balance in a microorganism and controlling a flow of ions in the microorganism from multiple surfaces. The preserving apparatus has a multiple surface electrode structure that includes a multiple surface electrode unit having at least one anode and cathode facing each other and located in a housing member of a preserving unit that stores an object disposed in the preserving apparatus; and a power supply unit that forms an electric field between the anode and the cathode by supplying a voltage to the anode and the cathode; wherein the power supply unit sequentially or randomly supplies the voltage to the at least one anode and cathode.

Abstract: A bio cartridge measuring analytes contained in a test sample includes: a first measurement area provided to measure a first analyte contained in the test sample; a second measurement area provided to measure a second analyte contained in the test sample; a separation area provided to separate the first measurement area from the second measurement area; a sample channel shaped in capillary shape between the first and second measurement areas; an air outlet provided to discharge air when the test sample is filled in the first and second measurement areas; and an agitation unit mixing the test sample with a reactive sample in at least one of the first and second measurement areas, in which a reactive sample reacting with the first or second analyte is applied on an inner wall of at least one of the first and second measurement areas.
