Abstract
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.
Claims12
A filter device, comprising:
- a microstructure filter comprising cross channels that filter a fluid flowing from inlet channels to outlet channels, the cross channels comprising microstructure filter features formed by etching away a portion of sacrificial layers, the microstructure filter features including a coating interacting with chemical particles present in the fluid to attract the chemical particles to the coating as the fluid flows through the filter device;
- the coating of the microstructure filter features comprising nanostructures that increase a surface area of the microstructure filter features, the nanostructures including nanoscale three-dimensional elements coated throughout a plurality of surfaces of the microstructure filter features.
