Previous studies on light-driven droplet transport often use light to heat the substrate generate a temperature difference, thereby changing wettability or surface tension at two ends of droplet, propel forward, and not much attention has been paid droplets with photothermal properties. Herein, we introduce method ink manipulation via near infrared lubricant infused surfaces. Rather than heating itself, this uses near-infrared irradiate one end an creating gradient inside it forming Marangoni flow that pushes forward. It is demonstrated would experience stages during sliding, movement ability depends their absorbance size; specifically, average acceleration steady velocity are both positively correlated negatively volume. The work only proves can realize conventional individual such as controllable along arbitrary paths, but also proposes unique customized merging strategy for multiple droplets. This investigation offers simple versatile approach droplets, relevant results have potential applications in fields precise maneuver droplet-based inkjet printing.
