Publication number: 20180135111Abstract: The present invention relates to a method and an apparatus for ultrasensitive quantitative analysis of a DNA biomarker, and more particularly, provides a method and a kit for quantitative analysis of target DNA using an atomic force microscope. The DNA quantification according to the present invention enables the quantification of target DNA at low concentration, which has been difficult to carry out by a conventional method, through adhesion force mapping by using an atomic force microscope, and does not result in DNA amplification and transformation nor require the use of a fluorescent marker. In particular, the method applies the size optimization of a probe DNA spot generated to capture target DNA, thereby enabling the quantitative analysis of ten or less target DNA molecules on various substrates.Type: ApplicationFiled: June 28, 2017Publication date: May 17, 2018Inventors: Joon Won Park, Yoonhee Lee, Youngkyu Kim, Donggyu Lee

Publication number: 20170276671Abstract: The present invention provides a regenerated cellulose membrane (RCM) that is useful in analysis of a sample for the presence of or the amount of a target molecule present in the sample. The invention also provides a method for producing and using the same. The RCM of the invention has a plurality of RCM functional groups on its surface in which a linker is covalently attached. The linker has a distal end and a proximal end, where the proximal end comprises at least one RCM linking functional group such that the RCM linking functional group is attached to the RCM functional group. The distal end of the linker comprises a receptor linking functional group that is used to covalently attach a receptor molecule. The receptor molecule is adapted for binding to a target molecule of interest when the target molecule is present in the sample. The RCM of the invention can be used for quantitative and/or qualitative analysis of a target molecule within the sample.Type: ApplicationFiled: November 14, 2016Publication date: September 28, 2017Applicant: NB Postech, Inc.Inventors: Joon Won PARK, Sung Min SEO, Jong Myung KO
