Maintaining Functionality of Biological Materials during Fluid–based Manufacturing
Drop on demand inkjet printing and extrusion–based printing enable 2D and 3D structures to be produced with high spacial resolution, highly applicable for the pharmaceutical industry where constructs can be used for tissue engineering, drug discovery and drug delivery applications. However, both of …

Investigation of a trapezoidal microchannel for hydrodynamic detachment of cells or biomolecules.
Fluid-based non-specific adsorption (NSA) methods and cell adhesion studies both use hydrodynamic forces to detach biomolecules or cells. To address the limitations in current microfluidic detachment assays and NSA removal methods, a trapezoidal microchannel was investigated as a hydrodynamic …
