Abstract Modern biomedical applications such as targeted drug delivery require a delivery system capable of enhanced transport beyond that of passive Brownian diffusion. In this work, an osmotic mechanism for the propulsion of a vesicle immersed in a viscous fluid is proposed. By maintaining a steady-state solute gradient inside the vesicle, a seepage flow of the solvent (e.g. water) across the semipermeable membrane is generated, which in turn propels the vesicle. We develop a theoretical…

Forced microrheology of active colloids
This work shows that active suspensions exhibit a swim-thinning behavior in which their microviscosity is gradually lowered from that of passive suspensions as the swim speed increases, and shows that this behavior originated from the interplay between the suspension activity and the hard-sphere excluded-volume interaction between the probe and a bath particle.
Encapsulated bacteria deform lipid vesicles into flagellated swimmers
A physical coupling between the membrane tube and the flagella of the enclosed cells transforms the tube into an effective helical flagellum propelling the vesicle, and points to novel design principles for conferring motility to synthetic cells.


The force on a boundary in active matter
We present a general theory for determining the force (and torque) exerted on a boundary (or body) in active matter. The theory extends the description of passive Brownian colloids to self-propelled
Acoustic trapping of active matter
The novel use of an acoustic tweezer to confine self-propelled particles in two dimensions over distances large compared with the swimmers' run length is reported, and a near-harmonic trap is developed to demonstrate the crossover from weak confinement, where the probability density is Boltzmann-like, to strong confinement,Where the density is peaked along the perimeter.

In this paper, an attempt has been made to model the dynamics of ciliary propulsion through the concept of an ‘envelope’ covering the ends of the numerous cilia of the microscopic organism. This
On the squirming motion of nearly spherical deformable bodies through liquids at very small reynolds numbers
A spherical deformable body can swim, at very small Reynolds numbers, by performing small oscillations of shape. However, the mean velocity of translation is a t most of the order of the square of

Analysis of the Brinkman equation as a model for flow in porous media
The fundamental solution or Green's function for flow in porous media is determined using Stokesian dynamics, a molecular-dynamics-like simulation method capable of describing the motions and
The hydrodynamics of an active squirming particle inside of a porous container
A microswimmer placed inside of a passive lamellar vesicle can hydrodynamically induce directed motion of the vesicle so long as fluid is permitted to pass through the vesicle's surface. With an
