Design principles for Bernal spirals and helices with tunable pitch
, 2014 Using the framework of potential energy landscape theory, we describe two in silico designs for self-assembling helical colloidal superstructures based upon dipolar dumbbells and Janus-type building blocks, respectively.

Passive Janus particles are self-propelled in active nematics
New Journal of Physics, 2022 While active systems possess notable potential to form the foundation of new classes of autonomous materials (Zhang et al 2021 Nat. Rev. Mater. 6 437), designing systems that can extract functional work from active surroundings has proven challenging. In

Active colloids at fluid interfaces
, 2016 If an active Janus particle is trapped at the interface between a liquid and a fluid, its self-propelled motion along the interface is affected by a net torque on the particle due to the viscosity contrast between the two adjacent fluid phases.

Active colloidal particles in emulsion droplets: A model system for the cytoplasm
, 2018 In living cells, molecular motors create activity that enhances the diffusion of particles throughout the cytoplasm, and not just ones attached to the motors. We demonstrate initial steps toward creating artificial cells that mimic this phenomenon.

Active Motion of Janus Particle by Self-thermophoresis in Defocused Laser Beam
, 2010 We study self-propulsion of a half-metal coated colloidal particle under laser irradiation. The motion is caused by self-thermophoresis: i.e. absorption of laser at the metal-coated side of the particle creates local temperature gradient which in turn ...
