Abstract:
A microchannel device includes a main chamber, a plurality of flow channels which are radially spaced from each other in the main chamber, connection channels which independently connect the flow channels to the main chamber, and a porous membrane which is formed in each connection channel. The porous membrane forms fine particles by combining fine particles using a solution including fine particles.

PURPOSE: An apparatus and a method for electrical measurement of cell deformation are provided to easily determine whether a sample cell is a normal cell or cancer cell according to the deformation degree. CONSTITUTION: An apparatus for electrical measurement of cell deformation comprises an electrode pair(110), a suction channel(100), a transfer channel, and a measuring unit(130). The electrode pair is arranged with a gap. The suction channel draws in a sample cell between the electrode pair. The suction channel transports the sample cell to the suction channel. The measuring unit is connected to the electrode pair and measures the electrical characteristics between the electrode pair in order to determine the deformation degree of the sample cell.

PURPOSE: A method for forming a polymer membrane with a micro channel and a micro channel apparatus formed by the same are provided to quantitatively adjust the thickness of the polymer membrane by gelation. CONSTITUTION: A micro channel structure includes a first flow path(110), a second flow path(120), and a combining flow path(130) combining the first flow path and the second flow path. A first solution(40) and a second solution(50) are respectively supplied along the first flow path and the second flow path. The first solution and the second solution are combined to form a laminar flow along the combining flow path. A cross-linking reaction is implemented at the interface of the first solution and the second solution in the combining flow path to form a polymer membrane along the interface of the first solution and the second solution.
Abstract:
PURPOSE: A sensor for detecting the porosity and a manufacturing method are provided to detect whether a target exists or not according to characteristics of lights observed in outside corresponding to an amount of the target. CONSTITUTION: A sensor for detecting the porosity comprises a sensor layer(110). A plurality of pores(120) having a minute diameter is distributed inside the sensor layer. Whether a target exists or not is decided according to characteristics of lights observed in outside corresponding to an amount of the target remained inside the pores of the sensor layer. The characteristics of lights are observed in a viewable range, an ultraviolet range, and infrared range within a specific frequency range.
