Fig. 4: Selective release of droplets stabilized by f-Au@SiO2 in a 5 × 5 floating trap array.
From: On-demand light-driven release of droplets stabilized via a photoresponsive fluorosurfactant
The release pattern was defined by a 5 × 5 binary number array. The letters “C” and “U” were formed by droplets trapped in the 5 × 5 floating trap array after automated and selective release
