20100012575 | Channel Filter Having Surface Topology For Filtering Micro Particles And Method For Manufacturing Same - Disclosed is a channel filter for separating microparticles, and more particularly to a channel filter which can easily separate a sample having various sized microparticles by using a surface topology. In the disclosed channel filter, a topology having an upward/downward reference height from a sample inlet to an outlet is continuously or discontinuously formed, and thus it is possible to efficiently separate microparticles from a sample liquid. | 01-21-2010 |
20110030458 | CHIP FOR ANALYZING FLUIDS - Disclosed is a fluid analysis chip including a microchannel formed within the chip. The chip includes a sample and a sample outlet communicating with an outside of the chip, and has a structure where the sample inlet and the sample outlet communicate with each other through the closed channel. An expanding part formed in a longitudinal direction of a channel in such a manner that a pair of inner walls corresponding to each other has a larger sectional area at a part or a whole thereof is formed. Therefore, fluids, which pass through the channel adjacent to the expanding part, move while making contact with only another pair of inner walls of the channel, which correspond to each other. | 02-10-2011 |
20110085031 | FLUORESCENT MICROSCOPE AND REMOTE CONTROL SYSTEM THEREOF - The present invention relates to a fluorescent microscope and a remote control system thereof. The present invention reduces the size of the fluorescent microscope to facilitate transportation and management and be disposed in a narrow place such as the inside of the incubator or the clean bench, etc. and observes the samples through a remote control, thereby making it possible to improve the user convenience. | 04-14-2011 |
20110294197 | MODULE FOR DETECTING ANALYTES IN FLUIDS AND CHIP HAVING THE SAME - Disclosed is a module for rapidly detecting analytes in fluids with high effectiveness and a chip having the module. The module includes a microchannel, which has a filtering zone for removing noise materials and a reaction zone wherein labeling reaction and immobilization reaction for detection of analytes are performed, sample fluid moving through the microchannel due to capillary floating. In a case where the chip having the module is used in detecting analytes in fluids, it is possible to minimize dead volume of sample fluid so that high effective volume ratio can be implemented. Therefore, the chip can be used in detecting analytes from the minimum amount of sample fluid. | 12-01-2011 |
20120003725 | MICROFLUIDIC CHIP FOR ANALYSIS FOR FLUID SAMPLE - Disclosed is a microfluidic chip capable of accurately and quickly detecting presence of a trace amount of a target within a fluid sample. It has a channel structure comprising a sample inlet for feeding a sample therethrough, a first reservoir for primarily storing the sample therein, a second reservoir for secondarily storing the sample therein, a first reaction portion in which a target is conjugated with a label, a second reaction portion in which the labeled target undergoes a specific reaction, such as an antigen-antibody reaction, and a delaying portion, located between the first and the second reaction portion, for decreasing a flow rate of the sample. | 01-05-2012 |
20130201322 | FLUORESCENT MICROSCOPE FOR OBSERVING MULTIPLE FLUORESCENT IMAGES, FLUORESCENT IMAGE SURVEYING METHOD USING THE SAME, AND MULTIPLE FLUORESCENT IMAGE OBSERVING SYSTEM - A fluorescent microscope for observing multiple fluorescent images includes: a first optical module comprising a first light source for supplying first excitation light having a first wavelength, a first excitation filter for selectively transmitting the first excitation light supplied from the first light source, a first dichroic filter for reflecting the first excitation light having passed through the first excitation filter toward the survey object, an objective lens for condensing the first excitation light reflected by the first dichroic filter and transferring the condensed first excitation light to the survey object, a second dichroic filter for reflecting first radiation light radiated from the survey object, a first radiation filter for selectively transmitting the first radiation light reflected by the second dichroic filter, and a first image acquisition unit for acquiring an image by using the first radiation light having passed through the first radiation filter to be supplied; and a second optical module comprising a second light source for supplying second excitation light having a second wavelength, a second excitation filter for selectively transmitting the second excitation light supplied from the second light source, a second radiation filter passing through the second excitation filter and irradiated to the survey object to be radiated, to selectively transmitting the second radiation light EM | 08-08-2013 |
20140370620 | MULTIMER TYPE DISCRIMINATION AND DETECTION METHOD FOR MULTIMER-FORMING POLYPEPTIDE - The present invention relates to a method for selectively detecting a multimer type multimer-forming polypeptide in a biological sample, the method comprising: (a) bringing the biological sample into contact with an agglutination reaction inducing agent to induce the formation of an aggregate in an analysis target, the agglutination reaction inducing agent being a particle in which a specific antibody is surface-bonded with the multimer-forming polypeptide; (b) obtaining an image with respect to the aggregate of step (a); and (c) analyzing a size or a shape of the aggregate by using the image. Step (a), step (b), or steps (a) and (b) are performed on a microchip having a microchannel. The image analysis is performed using a coefficient according to the size of the aggregate in a predetermined volume provided by the microchannel. In the case where the multimer type of multimer-forming polypeptide is present in the biological sample, the size of the aggregate is larger than the size of an aggregate of a monomer type control group. According to the present invention, unlike in a detection method using chemiluminescence immunoanalysis of the related art, an image with respect to an agglutination reaction target is obtained and then a size or a shape of an aggregate is analyzed so as to determine whether or not an analysis target is present in a biological sample and to determine the quantity of the analysis target. Also, it is possible to detect a multimer type multimer-forming polypeptide by just analyzing an image acquired from the sample so that the detection process is made more convenient and quick. | 12-18-2014 |
