Abstract
None:
Customizable 2.5D microfluidic chips, tailored for rock-on-a-chip studies, are developed using direct laser writing (DLW) and soft lithography. Chip microchannels feature varied cross-sectional shape and height, convergences as small as 1-2 µm, and controlled nanoscale surface roughness. The impact of these 2.5D features on pore-scale transport phenomena is demonstrated with trapped bubble dissolution experiments.
