Abstract
A composition useful for cell capture, the composition comprising a solid substrate on which is affixed a patterned polymer, and a cell-targeting agent attached to said patterned polymer, wherein said cell-targeting agent is exposed. Also described is a method for the preparation of the cell capturing composition, as well as flow through devices in which the cell capturing composition is incorporated. Further described is a method of capturing cells by contacting the cell-capturing composition with a liquid or gaseous sample containing cells. The method for capturing cells may also be a method for testing for the presence of one or more classes or species of cells or cellular organisms in a liquid or gaseous sample.
