Abstract
A microfilter having a hydrophilic surface and suited for size-based capture and analysis of cells, such as circulating cancer cells, from whole blood and other human fluids is disclosed. The filter material is photo-definable, allowing the formation of precision pores by UV lithography. Exemplary embodiments provide a device that combines a microfilter with 3D nanotopography in culture scaffolds that mimic the 3D in vivo environment to better facilitate growth of captured cells.
