Figure | Working mechanism of programmable cell rotation. (A) Programmable optical patterns generate thermo-osmotic flows at the functionalized plasmonic interface. (B) BSA-functionalized AuNIs and PEG-induced depletion forces stabilize cells near the substrate. (C) A Gaussian laser spot drives major-axis rotation through thermo-osmotic torque. (D) A half-ring laser pattern induces minor-axis rotation through coupled thermo-osmotic and optical torques.
