Method for capturing target cells or molecules in solution
Disclosed is a method for capturing target cells or molecules in solution, comprising steps of: (I) getting medium containing said target cells or molecules into an apparatus comprising a capturing device for capturing said target cells or molecules; (II) getting said medium flow through said capturing device; (III) removing unbound debris, cells and molecules; (IV) getting said target cells or molecules detached from the capturing device; and (V) collecting said target cells or molecules; wherein said capturing device comprises at least one functionalized mesh comprising a mesh substrate and a functional layer formed on said mesh substrate, wherein said functional layer comprises capturing substances that can specifically bind with said target cells or molecules. The method has high specificity, as well as high throughput, and is suitable for capturing cells or molecules in a solution or expressed at the surface of cell membranes. It is particularly suited to capture and sort circulating tumor cells.
Multiple laminar flow-based particle and cellular separation with laser steering
The invention, provides a method, apparatus and system for separating blood and other types of cellular components, and can be combined with holographic optical trapping manipulation or other forms of optical tweezing. One of the exemplary methods includes providing a first flow having a plurality of blood components; providing a second flow; contacting the first flow with the second flow to provide a first separation region; and differentially sedimenting a first blood cellular component of the plurality of blood components into the second flow while concurrently maintaining a second blood cellular component of the plurality of blood components in the first flow. The second flow having the first blood cellular component is then differentially removed from the first flow having the second blood cellular component. Holographic optical traps may also be utilized in conjunction with the various flows to move selected components from one flow to another, as part of or in addition to a separation stage.
