Abstract:
A filter chip and a manufacture method thereof are provided to obtain maximum amount of blood plasma by increasing capillary force of a fluid inlet and to remove blood cells and minute particles, which obstruct diagnosis or analysis. A filter chip comprises: a filter(130); a lower plate structure(110) with a groove(111) formed therein in order to settle the filter; an upper plate structure(120) covering the upper area of the lower plate structure; a fluid inlet(140) formed in one region of the upper plate structure in order to inject fluids; and a fluid outlet(150) formed lower than the fluid inlet in order to flow the fluid out. The width of the filter and groove becomes narrow from the fluid inlet side to the fluid outlet side so as to induce rapid capillary force as the fluid passes through the filter.

Abstract:
A serum separator is provided to improve convenience of manufacturing and automatically separating serum from the blood by simple pumping without additional devices by arranging the separation member for separating blood corpuscles from the blood without blood corpuscle accumulation to the microchannel. A serum separator for separating serum from whole blood comprises: a body having a cover substrate(500) and a channel substrate(550) which are conjugated each other; a microchannel(400) formed in the body through which the introduced blood(930) flows; separation member(300) formed in the microchannel for separating serum and blood corpuscles by disturbing the flow of blood corpuscles or serum in blood; a blood inlet part(100) communicated with the microchannel; and a blood outlet part(200) communicated with the microchannel. Further, a chemical treating part for increasing a separating efficiency between the serum and the blood corpuscles is additionally contained on the microchannel.
Abstract:
A surface modification process of a cycloolefin copolymer substrate is provided to allow easy modification of cycloolefin copolymer substrate, which, otherwise, is not be amenable to surface modification, and to fix various bioactive substances stably to the surface, thereby facilitating production of biosensor chips. A surface modification process of a cycloolefin copolymer substrate comprises the steps of: treating the surface of a cycloolefin copolymer substrate with oxygen plasma to produce hydroxyl groups on the surface of the substrate; treating the oxygen plasma-treated substrate with an acid; and fixing at least one compound having a functional group to the acid-treated substrate. The oxygen plasma treatment is performed at 10-500 W for 2-30 minutes under an oxygen flow rate of 10-500 sccm.
Abstract:
A monolithic MEMS(Micro-Electro Mechanical System) sensor without a step and a method of fabricating the same are provided to use a quality high temperature deposited layer for an MEMS since formation of a membrane is performed before a metal wiring process of a reading circuit. In a monolithic MEMS sensor without a step, an MEMS is formed on a left side of a substrate(10) as a first region. A reading circuit(50) is formed on a right side of the substrate as a second region. The MEMS includes a protection layer(20), a membrane(40), an insulation layer(41), and a sensor electrode(60) on the substrate. The protection layer is formed of a silicon oxide layer or a silicon nitride layer. The membrane is formed on a top of the protection layer as a silicon nitride layer or a silicon oxide layer. The insulation layer is formed of a silicon oxide layer. The sensor electrode is formed of a conductive material on the insulation layer. And, a sacrificial layer burying a trench is removed by an etching path(70).
