Description

technical field

[0001] The invention relates to the field of purification of biological samples. More specifically, the present invention relates to devices and methods capable of isolating minute amounts of target cells from liquid samples containing various other cells and / or contaminants. Background technique

[0002] Efficient and effective separation of various components in biological samples is necessary in various fields of research and medicine. Many liquid samples contain many types of cells and / or contaminants of little or no interest, and few cells of interest for further evaluation. Therefore, it would be desirable to be able to isolate minute amounts of target cells from a large number of normally occurring cells, such as blood cells or epithelial cells.

[0003] Various techniques already exist in the art for meeting this need. For example, it is known to pass a liquid sample through a filter, thereby purifying certain components of the sample. US Patent 7...
