(Top) Schematic showing near-infrared light-based control of a liquid droplet infused with polypyrrole (PPy) nanoparticles. Upon irradiating one side of the PPy-infused droplet, the nanoparticles absorb the light and heat up, inducing Marangoni flow caused by a temperature gradient. Real and infrared images of PPy aqueous dispersion (bottom left) and deionized water (bottom right) droplet during droplet manipulation by NIR laser.
