Brownian dynamics simulation of charged dendrimers:Dynamic properties [PDF]
, 2004 \u3cp\u3eThe dynamic properties of neutral and charged dendrimers in dilute solutions are studied using the method of Brownian dynamics simulation. Excluded-volume, electrostatic, and hydrodynamic interactions are taken into account. A scale hierarchy is

Computer simulation on the collision-sticking dynamics of two colloidal particles in an optical trap
, 2007 Collisions of a particle pair induced by optical tweezers have been employed to study colloidal stability. In order to deepen insights regarding the collision-sticking dynamics of a particle pair in the optical trap that were observed in experimental ...

Responsive Materials, EarlyView.Electrostatically charged aerosol magnetic nanoparticles enable template‐free self‐assembly of nanochains with tunable length and spacing by adjusting electric‐to‐magnetic field ratios. Lower electric fields favor the self‐assembly of longer and more spatially separated chains, while higher electric fields promote a uniform nanoparticle deposition and ...

Surface Locomotion of Cell‐Sized Microrobots Subject to Adhesive Heterogeneity
Small, EarlyView.Chemically powered, cell‐sized microrobots exhibit translational, circular, or spiral motion through a balance among self‐phoretic propulsion, drag, gravity, and heterogeneous surface interactions. Experiments show that microrobot design and substrate conditions regulate both mobility and trajectory type.

Small, EarlyView.Single‐frequency magnetic particle spectroscopy (MPS) and frequency‐mixing (FM‐)MPS exhibit complementary viscosity‐dependent signal responses of magnetic nanoparticles (MNP). MPS differentiates predominantly blood‐associated viscosities, whereas FM‐MPS shows pronounced discriminability in cellular and tissue‐like viscosity regimes (sensitivity windows)

Small, EarlyView.Oscillatory electro‐viscoelastic migration (Osc‐EVM) achieves focusing of particles as small as 20 nm in a 50 µm × 50 µm channel. The colloidal sample experiences sustained electro‐viscoelastic lift over extended durations, effectively prolonging the channel length to infinity by periodically reversing the flow direction and electric field.

VIEW, EarlyView.Plant‐derived nanovesicles (PDNVs) are naturally secreted by fruit, vegetables, seeds, leaves and other natural sources. Used as drug delivery systems, they can combine intrinsic therapeutic activity, enhanced skin permeation and cargo‐carrying capacity, suitable for dermatological and cosmetic applications including hydration, antioxidant/anti ...
