Active particles convert external energy into motility, displaying a variety of dynamical
features. Recent progress in the field has marked a shift in focus from understanding the …

One of the recent frontiers of nanotechnology research involves machines that operate at
nano-and microscales, also known as nano/micromotors. Their potential applications in …

Active colloids are a class of microparticles that 'swim'through fluids by breaking the
symmetry of the force distribution on their surfaces. Our ability to direct these particles along …

We experimentally study the motion of light-activated colloidal microswimmers in a
viscoelastic fluid. We find that, in such a non-Newtonian environment, the active colloids …

We study the diffusion of particles confined close to a single wall and in double-wall planar
channel geometries where the local diffusivities depend on the distance to the boundaries …

Using a dynamic fabrication process, hybrid, photoactivated microswimmers made from two
different semiconductors, titanium dioxide (TiO2) and cuprous oxide (Cu2O) are developed …

This article presents a computational approach for determining the optimal slip velocities on
any given shape of an axisymmetric micro-swimmer suspended in a viscous fluid. The …

We study the motion of an active Brownian particle (ABP) using the overdamped Langevin
dynamics on a two-dimensional substrate with periodic array of obstacles and in a quasi …

Using simulations, we examine the average velocity as a function of applied drift force for
active matter particles moving through a random obstacle array. We find that for low drift …

We study the dynamics of circular disk-shaped active particles on a two-dimensional
periodic undulated surface. Each particle has an internal energy mechanism which is …
