Abstract

We present a novel microfilter used for solutes separation by diffusion. The microfilter is composed of two micro chambers made of PDMS and one layer of porous membrane formed by wet phase immersion method using PES (polyethersulfone). A theoretical equation for the description of the diffusion in the microfilter was derived and verified to be capable of predicting concentration distributions. Filtering capacity for molecules with various molecule sizes of this microfilter was evaluated using solution samples of sodium chloride (NaCl) and FITC (Fluorescein Isothiocyanate) Dextrans (MW 4k, 20k, 70k and 250k). This microfilter can be applied to artificial kidneys which can be implanted in human bodies
