Abstract:
An apparatus for separating components and a method of separating components using the apparatus are provided. The apparatus includes: a main chamber which contains a sample that is separated into a plurality of layers by a centrifugal force; a component separating chamber which is connected to the main chamber, and receives a specific layer including specific components among the plurality of layers; a first channel which connects the component separating chamber to the main chamber; and a first channel valve which is disposed in the first channel to control a liquid flowing through the first channel.
Abstract:
Provided are nucleic acid structures suitable for reproducible Raman spectroscopy, methods of preparing the same, and methods of detecting a target material using the nucleic acid structures, whereby various target materials may be analyzed by using reproducible Raman spectroscopy.
Abstract:
A micro fluidic apparatus includes a sample chamber that divides a sample into a first fluid layer and a second fluid layer due to a centrifugal force; a first enriching unit a that receives the first fluid layer from the sample chamber, forms a first complex of a first fine particle and the first target material, and separates the first complex from the first fluid layer using a density difference; and a second enriching unit that receives the second fluid layer from the sample chamber, forms a second complex of a second fine particle and the second target material, and separates the second complex from the second fluid layer using a density difference.
Abstract:
A target affinity material comprising a biodegradable polymer, wherein the biodegradable polymer comprises one or more solid particles and one or more materials that specifically binds to a target, as well as related methods and kits.
Abstract:
Provided is method of diagnosing liver cancer in a subject, the method comprising contacting a sample from a subject with a substance that specifically binds to transmembrane emp24 domain trafficking protein 2 (TMED2), cluster of differentiation 43 (CD43), or any combination thereof on the surface of a microvesicle; and measuring the level of the substance bound to microvesicles in the sample; and related methods and compositions.
Abstract:
Provided is an interparticle spacing material comprising a nucleic acid structure which comprises at least one nucleic acid lattice comprising a double helix domain; and at least one metal particle which is in contact with a plane of the nucleic acid lattice, in a direction extending obliquely or perpendicularly away from the plane; wherein the double helix domain comprises a hybridization area in which a single strand is hybridized with another single strand.
Abstract:
A photocleavable polymer comprising a photocleavable linker and a polymer having a functional group that binds to a protein, lipid, sugar of a cell, or any combination thereof, as well as a method of selectively lysing cells by incubating a sample comprising two or more cells with the photocleavable polymer to reversibly fix the cells; selectively irradiating the fixed cells or a target or non-target cell among the fixed cells to cleave the photocleavable polymer; and adding a cell lysis solution to selectively lyse the irradiated cells.
Abstract:
Provided is a method of separating a rare cell from a sample comprising incubating a sample comprising a rare cell and a second cell with a particle comprising a moiety capable of binding to the rare cell to form a complex comprising the particle and the rare cell; applying the mixture to a medium having a density gradient; and centrifuging the mixture to separate the complex from the second cell.
Abstract:
