Manipulating liquid droplets have many potential applications, such as drug delivery and microfluidics. In this study, we introduce a new strategy to control the motion of liquid droplets on liquid repellent surfaces by using selective photothermal reaction. Since polypyrrole has good photothermal property, the polypyrrole nanoparticle dispersion droplet can quickly heat up under near IR irradiation. Therefore, by the selective irradiation, the droplets successfully roll and/or slide on the surfaces with the internal flows of droplet from the temperature gradient. |
