摘要： Provided are a microfluidic chip for multiple bioassay and a method of manufacturing the same. The method includes: forming microfluidic channels by coupling a channel structure having grooves for sample channels and probe channels in a bottom surface and a substrate; forming probe immobilization regions at intersections between the probe channels and the sample channels; and forming blocking walls in the probe channels before and after each of the probe immobilization regions to prevent mixing of target sample. Since the probes are immobilized in the microfluidic channels after the formation of the microfluidic channels, difficulty in connecting fluidic channels after the immobilization of probes on a substrate can be removed. In addition, a microfluidic platform for a multiple bioassay into which a plurality of samples can be simultaneously loaded can be formed.

摘要： Provided are a sensing switch and a sensing method using the same. The sensing switch includes: a substrate; a supporter on the substrate; a sensing plate that is connected to a side of the supporter and is in parallel with the substrate by a predetermined distance; a receptor binding region on an upper surface of an end portion of the sensing plate; an electric or magnetic field generation device that induces deflection of the sensing plate when a receptor bound to the receptor binding region is selectively bound to an electrically or magnetically active ligand; and a pair of switching electrodes that are separated by a predetermined distance and is connected when the sensing plate contacts the substrate due to the deflection of the sensing plate. A target material need not be labelled, a signal processing of a fluorescent or electrical detection signal using an analysis apparatus is not required, and a signal can be directly decoded by confirming whether a current flows through the switch.

摘要： Provided is a method of isolating and purifying nucleic acids using an immobilized hydrogel or polyethylene glycol (PEG)-hydrogel copolymer. The method includes: immobilizing a functional group-containing hydrogel or PEG-hydrogel copolymer on a substrate; adding a mixed sample solution containing a salt and nucleic acids to the hydrogel- or PEG-hydrogel copolymer-immobilized substrate to bind the nucleic acids to the hydrogel or the PEG-hydrogel copolymer; washing the nucleic acid-bound hydrogel or PEG-hydrogel copolymer; and eluting the nucleic acids from the hydrogel or the PEG-hydrogel copolymer using an elution solvent. Therefore, binding and elution of nucleic acids can be performed even with no addition of a separate chemical substance, and an effect on a subsequent process such as PCR can be minimized. Furthermore, the amount and intensity for binding nucleic acids can be adjusted according to PEG concentration, and the presence of a hydrogel compound on a substrate enables patterning.

摘要： A method and apparatus for amplifying nucleic acids. The method includes introducing into a reaction vessel via different inlet channels a reactant aqueous solution containing reactants for nucleic acid amplification and a fluid that is phase-separated from the reactant aqueous solution and does not participate in amplification reaction, creating a plurality of reactant aqueous solution droplets surrounded by the fluid by contacting the reactant aqueous solution with the fluid in the reaction vessel, and amplifying the nucleic acids in the reactant aqueous solution droplets. The apparatus includes a substrate, a reaction vessel formed inside of the substrate, at least one first inlet channel formed inside the substrate, connected to an end of the reaction vessel, and allowing introduction of a reactant aqueous solution containing reactants for nucleic acid amplification into the reaction vessel, a second inlet channel formed inside the substrate, connected to the end of the reaction vessel, and allowing introduction of a fluid that is phase-separated from the reactant aqueous solution and does not participate in amplification reaction into the reaction vessel, and a heating unit installed on the substrate in such a way to thermally contact with the substrate and heating the substrate.
