摘要： The present disclosure relates to a membrane extraction apparatus for extracting a component from a first liquid. The apparatus may incorporate a housing comprised of first and second mating housing halves, with each housing half having an open faced channel formed therein such that the channels at least partially overlay one another when the two housing halves are secured together. A membrane filter is disposed between the two housing halves to overlay the open faced channels. The membrane filter extracts the component from the first liquid and transfers the component into the second liquid as the first and second liquids flow through the first and second housing halves.

摘要： Microstructure separation filters are provided herein, as well as chromatography and other separation devices. An exemplary filter device includes a microstructure filter has a plurality of layers of alternating sacrificial and/or structural material which have been etched to create inlet channels and outlet channels. Adjacent ones of the inlet channels and the outlet channels are spaced apart from one another by cross channels that filter a fluid from the inlet channels to the outlet channels. The cross channels include filter features formed by etching away of a portion of the layers. The device also includes a housing configured to receive the microstructure filter.

摘要： A process for manufacturing a micromechanical structure envisages: forming a buried cavity within a body of semiconductor material, separated from a top surface of the body by a first surface layer; and forming an access duct for fluid communication between the buried cavity and an external environment. The method envisages: forming an etching mask on the top surface at a first access area; forming a second surface layer on the top surface and on the etching mask; carrying out an etch such as to remove, in a position corresponding to the first access area, a portion of the second surface layer, and an underlying portion of the first surface layer not covered by the etching mask until the buried cavity is reached, thus forming both the first access duct and a filter element, set between the first access duct and the same buried cavity.

摘要： A system for ultrafiltration employs a crossflow filtration module for extracting a fraction from a sample fluid (e.g., blood) and a recirculating permeate loop to produce a concurrent permeate flow through the filtration module to maintain a positive transmembrane pressure at all points of the crossflow filter. Permeate in the recirculating loop is enriched by a processing module and stabilized by removing an enriched fraction thereof. In an embodiment, the enriched fraction is concentrated plasma that is returned to a patient.

摘要： Nanopatterned substrates can be prepared by a method that includes forming a block copolymer film on a substrate, annealing the block copolymer film, surface reconstructing the annealed block copolymer film, coating an etch-resistant layer on the surface reconstructed block copolymer film, etching the resist-coated block copolymer film to create an etched article comprising a nanopatterned substrate, and separating the etch-resistant layer and the block copolymer film from the nanopatterned substrate. The method is applicable to a wide variety of substrate materials, avoids any requirement for complicated procedures to produce long-range order in the block copolymer film, and avoids any requirement for metal functionalization of the block copolymer.
