20090057599 | ELASTIC VALVE AND MICROFLUIDIC DEVICE INCLUDING THE SAME - An elastic valve and a microfluidic device including the same are provided. The elastic valve includes a channel dented by external pressure so as to be elastically restituted; and a plurality of channel closing protrusions, which comprise elastomer as a material, which are protruded from at least one inner side surface of the channel toward an opposite inner side surface, and which are separated from each other so as not to interrupt a flow of fluids, wherein, when external pressure is applied in order to dent the channel, the plurality of channel closing protrusions are deformed so as to be elastically restituted, thereby closing the channel. | 03-05-2009 |
20100221728 | METHOD FOR QUANTIFYING INITIAL CONCENTRATION OF NUCLEIC ACID FROM REAL-TIME NUCLEIC ACID AMPLIFICATION DATA - Provided is a method for quantifying an initial concentration of a nucleic acid from a real-time nucleic acid amplification data. Nucleic acid (DNA or RNA) extracted from organism or virus is amplified using an enzyme. Then, the initial concentration of the nucleic acid is found by calculating the characteristic amplification cycle number or the characteristic amplification time at which the fluorescence intensity of the nucleic acid subtracted by the background fluorescence intensity of the nucleic acid has half of its maximum value, or the characteristic amplification cycle number or the characteristic amplification time at which the amplification efficiency has the maximum or the minimum value, or the prior-to-amplification fluorescence intensity of the nucleic acid subtracted by the background fluorescence intensity of the nucleic acid. Accordingly, the initial concentration of the nucleic acid can be calculated without differentiation or integration. | 09-02-2010 |
20100311070 | POLYMERASE CHAIN REACTION (PCR) MODULE AND MULTIPLE PCR SYSTEM USING THE SAME - Provided are a PCR module and a multiple PCR system using the same. More particularly, provided are a PCR module with a combined PCR thermal cycler and PCR product detector, and a multiple PCR system using the same. | 12-09-2010 |
20110089034 | DIELECTROPHORESIS APPARATUS INCLUDING CONCENTRATION GRADIENT GENERATING UNIT, METHOD OF SEPARATING MATERIAL USING THE SAME, AND METHOD OF SCREENING CONDITION FOR SEPARATING MATERIAL - A dielectrophoresis (DEP) apparatus including a concentration gradient generating unit, a method of separating a target material in a sample solution using the DEP apparatus, and a method of screening the optimum condition for separating a target material are provided. | 04-21-2011 |
20110121196 | MICROFLUIDIC DEVICE, LIGHT IRRADIATION APPARATUS, MICORFLUIDIC SYSTEM COMPRISING THE SAME AND METHOD FOR DRIVING THE SYSTEM - A microfluidic system includes a microfluidic device including a chamber which contains a fluid sample, a channel which is connected to the chamber and through which the fluid sample flows, and a valve which controls flow of the fluid sample through the channel; an irradiation apparatus which irradiates electromagnetic energy; and a diffuser which diffuses and distributes the electromagnetic energy irradiated by the irradiation apparatus to an irradiation region of the microfluidic device. | 05-26-2011 |

Accordingly, the initial concentration of the nucleic acid can be calculated without differentiation or integration. | 10-06-2011 |
20120160792 | DETECTING DEVICE PACKING TRAY - A detecting device packing tray is provided which prevents a detecting device from being contaminated and damaged. The detecting device packing tray includes a tray main body configured to support a detecting device including a detection region to detect a reaction result. The tray main body includes a non-contact groove provided at a position corresponding to the detection region of the detecting device when the detecting device is supported by the tray main body so that the detection region does not contact the tray main body. | 06-28-2012 |
20120255871 | APPARATUS AND METHOD FOR ADJUSTING PH OF SOLUTION - A pH adjusting apparatus includes an electrolytic chip receiving a solution, an electrolytic chip loading station receiving the electrolytic chip, an input unit inputting electrolysis conditions, a control unit receiving the electrolysis conditions and controlling electrolysis performed in the electrolytic chip, and a display unit displaying the electrolysis conditions and a progress of the electrolysis. Thus, the pH of a solution can be adjusted easily and accurately, by precisely controlling a constant current, a constant voltage, and current and voltage application times, thereby enabling useful application in various biological assays such as cell lysis. Furthermore, the pH adjusting apparatus has small size and weight and can be operated for a long time after charging once due to low power consumption. | 10-11-2012 |
