Laser Controlled Manipulation of Microbubbles on a Surface with Silica‐Coated Gold Nanoparticle Array (Small 49/2023)
Source abstract
Abstract
Gold Nanoparticles In article number 2302939, Yuliang Wang and co-workers present a method that enables robust vertical manipulation of microbubbles produced at a silica coated nanoparticle array through laser irradiation. By implementing laser on/off control, they achieve robust bubble bouncing with adjustable size and frequency, guided by the interplay of the buoyancy force and laser irradiation-induced thermal Marangoni flow. The proposed approach opens up pathways for diverse applications in microfluidic devices, such as efficient fluid mixing and pumping, drug delivery, and the development of soft actuators and sensors.
