Chiral Opto‐Fluidics and Plasmonic Nanostructures as a Functional Nanosystem for Manipulating Surface Deformations

Abstract Photothermal conversion of energy in plasmonic nanostructures brought a new fascinating field plasmon‐induced optofluidics to life. Notably, the heat generation by and consequent fluid convection recently attracted wide attention; however, possibility controlling manipulating liquid surfaces has been sparsely investigated. The plasmon heating convective flow lead emergence surface tension gradient on free interface with air, resulting Marangoni effect‐driven observed as water deformation. Here, nanoscale asymmetric deformation anchored chiral optofluidic effect is reported on. To understand dynamics deformation, theoretical model developed. results demonstrate that at different depths can be obtained adjusting structural parameters or incident light intensity. fundamental understanding light‐induced will contribute expanding chirality‐related discipline open avenues for micro‐ nano‐scale. proposed method encourage research applications optofluidics, including integrated fluidic devices, biochemistry, clinical biology. Moreover, use thermal dewetting thin films polymer solutions employed fabrication functional nanopatterned metal/polymer metasurfaces.
