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.

Polymer microfilters, devices comprising the same, methods of manufacturing the same, and uses thereof

An instrument to acquire and methods to obtain three-dimensional (3D) images from a series of two-dimensional (2D) images which are obtained without moving the relative positions of the target, the detector, or the focusing lens is disclosed. The 2D images consist of one centered image obtained with the aperture at the center of optical system, and at least two directional images obtained with apertures at off-axis locations. The images can be obtained simultaneously or sequentially. The blurred 2D images are sectioned by computational method using point spread function of the optical system resulting in a set of decoupled 2D layers of the 3D object. The layered images are then sharpened by deconvolution using point spread function. The 3D reconstructed image is displayed. This technique provides fast data acquisition and fast image reconstruction and eliminates problems associated with motion, phototoxicity and photobleaching.
