Magnetically assisted and accelerated self-assembly of strawberry-like nano/microparticles
Article Abstract:
A novel method to reliably pattern strawberry-like microspheres that employs magnetically directed and accelerated self-assembly of nano/microparticles in aqueous solution, without the use of a template is introduced. The results reveal that 100-1000 nm paramagnetic 'decorating particles' rapidly self-assemble onto the surface of fluorescent 4-5 mum spherical magnetized 'core particles,' to produce strawberry-like particles with stable and precisely arranged microstructures.

Metal-capped brownian and magnetically modulated optical nanoprobes (MOONs): micromechanics in chemical and biological microenvironments
Article Abstract:
Modulated optical nanoprobes (MOONs) are microscopic (spherical and aspherical) fluorescent particles designed to emit varying intensities of light in a manner that depends on particle orientation. The methods by which tracking angular fluctuations allow sensitive measurements of torques acting on Brownian MOONs are studied.

Sudden breakdown in linear response of a rotationally driven magnetic microparticle and application to physical and chemical microsensing
Article Abstract:
Sensing magnetic microparticles were used to probe both the local pH and the viscosity-dependent nonlinear rotational behavior of the particles. The transition from simple rotation to wobbling is described both theoretically and experimentally.
