   • [Summary] A straightforward microfabrication process for multi-level microfluidic devices using maskless writer. We validated the hydrodynamics performance of the microfluidic chip by both finite element and finite volume methods (COMSOL Multiphysics and openFOAM). Although it is known that the mineral oil dries over time and the oil on oil immersion objective has to be cleaned up, to our knowledge it is the first report that drying of oils increase it's viscosity over time but not the refractive index. Certain oils with increased viscosity due to aging caused ghosting effects and slowly drift away from the desired focus over time, limiting the total duration of live bacterial imaging. By identification of this issue and careful choice of immersion oil, we can maintain the focus and crispy imaging of bacterial dynamics over days.

   • [Summary] By using a hybrid PMMA/PDMS microdevice to study the electrotaxis of glioblastoma. We identified that T98G and U-251MG glioblastoma cell lines has opposite electrotactic and electroalignment behavior. Also, the electrotaxis of glioblastoma cell lines depends on the laminin extracellular matrix, which in the brain is exclusively associated with the vasculature, suggesting a link to the peri-vascular microenvironment. The role of voltage gated calcium channels are further investigated in the electrotaxis of glioblastoma cells.

   • [Summary] A novel quick-fit hybrid PMMA/PDMS microdevice is developed and proved by studying a glioblastoma adhesion model. Over 150 V/m electric field, the electroalignment effect modulated the parallel alignment of the shear flow on the endothelial cells. We also observed the intercellular transport event suggesting that indeed cancer cells and fuse with endothelial cells.

   • [Summary] It is very difficult to create uniform electric fields from two electric potentials in a circular chamber due to differences of electric resistances. We employed a rational 3D computer aided design (CAD) approach of a microfluidic structure to equalize the electrical resistances in the chamber. A polymer insert with CAD structures can create uniform electric field in wells of multi-well plates or tissue culture dishes very much like a transwell insert. We hope this design of insert can be useful to push electric field stimultion into standard biomedical laboratory. Also the design strategy could be useful for different disciplines.
