Patent number: 8828334Abstract: 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.Type: GrantFiled: July 23, 2008Date of Patent: September 9, 2014Assignee: Nanoentek, Inc.Inventors: Jun Ha Park, Chang Seop Lee, Hyun Chang Lim, Chan Il Chung, Jun Keun Chang

Publication number: 20130071835Abstract: The present invention relates to a qualitative and quantitative analytical method for analyzing the activity type of an enzyme that is activated by proteolysis. The method of the present invention is advantageous in that the activity type of an enzyme present in a specimen is analyzed using an enzyme activity inhibitor and a binder to enable the analysis to be performed in a quicker and more accurate manner as compared to enzyme-activity analysis methods using a simple binder (for example, an antibody). The method of the present invention can enable the analysis of the activity type of an enzyme present in a specimen in a simple manner using less equipment than enzyme-activity analysis methods using a simple binder.Type: ApplicationFiled: May 25, 2011Publication date: March 21, 2013Applicant: Nanoenteck, Inc.Inventors: Chang Seop Lee, Seong Soo Alexander An, Min O.
