Abstract
Function fabrication in a microfluidic device manufactured with a custom 3D printer. The functions may include, for example, transporting or routing fluid, fluid mixing through flow and/or diffusion, blocking fluid (valve), pumping fluid, providing chemical reaction regions, providing analyte capture regions, and providing analyte separation regions. The fluid may be a liquid or a gas.
Claims20
A microfluidic device comprising,
- a structure of photo-cured resin,
- the structure of multiple adjacent layers of photo-cured resin with each layer having one or more resin regions of preselected cross-linking
- with multiple photo-cured resin layers of the photo-cured adjacent layers having one or more regions containing non-crosslinked resin where there is no crosslinking of resin, resulting in no resin or void regions when non-crosslinked resin is removed, such that void regions within multiple adjacent layers are disposed to provide a three-dimensional network of channels configured for microfluidic function.
