Electrochemically etched nanoporous silicon membrane for filtration of biological fluids

Many biological fluids require filtration during its processing, either to separate the various components in the fluid or to remove unwanted or harmful contaminants from the medium. Challenges arise in the filtration process as the masses to be filtered appear in various sizes [1]. Conventional filtration method requires lengthy and timely repeated processes. A simple solution to this problem is the isolation of the unwanted masses via sequenced filtration using precisely sized nanoporous silicon membrane.
