From: Backscattering particle immunoassays in wire-guide droplet manipulations
Snapshots from pre-programmed droplet movements. Top left: taking a 10 μL droplet of 0.02% (w/v) antibody-conjugated particle suspension by inserting a wire into the droplet; Top right: its linear movements; Bottom left: merging with a 10 μL target droplet; Bottom right: linear movements of this merged 20 μL droplet towards the detection site.
