Emergence Of Directional Rotation In Optothermally Activated Colloidal System
Rahul Chand, Chaudhary Eksha Rani, Diptabrata Paul +1
We experimentally demonstrate the emergence of directional rotation in thermally active-passive colloidal structures under optical confinement. The observed handedness of rotation…
Optothermal evolution of active colloidal matter in defocused laser trap
Diptabrata Paul, Rahul Chand, G V Pavan Kumar
Optothermal interaction of active colloidal matter can facilitate environmental cues which can influence the dynamics of active soft matter systems. The optically induced thermal e…
Optothermal pulling, trapping, and assembly of colloids using nanowire plasmons
Vandana Sharma, Sunny Tiwari, Diptabrata Paul +3
Optical excitation of colloids can be harnessed to realize soft matter systems that are out of equilibrium. In this paper, we present our experimental studies on the dynamics of si…
