Macrophage Uptake of Janus Particles Depends upon Janus Balance
, 2016 Properties of synthetic particles, such as size and shape, influence how immune cells uptake vaccine and drug carriers. Here, we explore the role of a new property, anisotropic presentation of ligands, in particle uptake by macrophage cells.

Janus Particles and Interfacial Activity [PDF]
, 2018 Janus particles are colloids with two different spatial domains. When these domains are synthesized with a contrast in wettability the particle shows an enhanced interfacial activity in comparison with the corresponding homogeneous particles.

Flagellar dynamics of chains of active Janus particles fueled by an AC electric field
New Journal of Physics, 2018 We study the active dynamics of self-propelled asymmetrical colloidal particles (Janus particles) fueled by an AC electric field. Both the speed and direction of the self-propulsion, and the strength of the attractive interaction between particles can be

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
