Figure 1From: Simple and reusable picoinjector for liquid delivery via nanofluidics approachDepiction of the interior of a silica nanochannel in the presence of a buffer solution. (a) Schematic showing the EDL and EO flow. (b) The corresponding potential at different layers. (c) Flow profiles of the laminar and electroosmotic flows when the channel dimension is beyond the electric double layer overlapping regime.Back to article page
