Droplets Manipulated on Photothermal Organogel Surfaces

Abstract: A photoresponsive organogel surface (POS), which integrates characteristics of the photothermal property of Fe 3 O 4 nanoparticles and the low hysteresis feature of lubricant-infused organogels, is shown. A photothermally induced dynamic temperature gradient can be formed rapidly at the location of nearinfrared-light irradiation (NIR) on POS with suitable Fe 3 O 4 nanoparticles content. Thus, various droplets (e.g., water, glycerol, ethylene glycol, propylene glycol, and ethanol) can be transported effectively… Show more

“…Other stimuli utilized to control the behaviors of droplets include temperature, photoirradiation, electric field and photoelectric synergetic effect . Widely studied thermal‐responsive polymers are used for fabricating thermal‐sensitive on‐demand liquid manipulators, such as poly( N ‐isopropylacrylamide) and paraffin .…”

“…Yang et al first introduced a microfluidic chip based on an anisotropic wetting substrate for anisotropic liquid flow and liquid–gas separation, and then they replaced the substrate with a thermal‐responsive anisotropic wetting substrate to facilitate temperature‐tunable liquid flow in microchannel . Different from other liquid photoactuators that were based on photoinduced wettability changes or Marangoni effect, Yu et al proposed a liquid crystal polymer tubular microactuator with tunable capillary force in response to light signals . Electric‐responsive on‐demand liquid manipulator had been reported as a result of the application of conductive surface, and more recently, photoelectric synergetic responsive surfaces emerged to apply multistimuli synergetic control of droplet because of the improved precision under complex environment …”

“…Based on the liquid droplet controllable transfer for microreactor, recently, Zheng's group developed a soft robot with mass transport ability. [89] They constructed a photo E-LIS through integrated lubricant swelling organogel and photothermal Fe 3 O 4 nanoparticles. With irradiation of near-infrared-light, a localized dynamic temperature gradient would be generated on the substrate.…”

“…[1,2] So far, several approaches, including the usage of electrowetting defects and the magnetic force, have successfully demonstrated the manipulation of droplets on an open surface. [6][7][8][9][10][11][12] For example, Ichimura et al achieved the remote light manipulation of liquids on an open surface modified with a photoresponsive azobenzene monolayer. [3][4][5][6][7][8][9] Compared to other stimuli, light allows a precise and remote control that can be regulated by tunable intensities and wavelengths, providing an alternative tool for the liquid manipulation.…”
