Cover Feature: Phototaxis Motion Behavior of a Self‐propelled Submarine‐like Water Droplet Robot in Oil Solvent (ChemNanoMat 11/2020)
Source abstract
Abstract
We all live in a yellow submarine: Different from previous robots, a light-driven self-propelled water-phase droplet microrobot, which is doped with Fe2O3 nanoparticles, moving in oil solvent is proposed. Fenton reaction occurs on the irradiated Fe2O3 nanoparticles. The continuous release of ferric ions and ferrous ions causes an uneven ion concentration to change the interfacial tension distribution between the water droplet and oil, generating Marangoni flow. The robot is constantly diving towards the light source like a submarine moving in an oil environment under blue laser irradiation. More information can be found in the Communication by Longqiu Li, Dekai Zhou et al.
