Magnetic Hydrogel Particles: Microfluidic Assembly of Magnetic Hydrogel Particles with Uniformly Anisotropic Structure (Adv. Mater. 31/2009)

The inside cover shows magnetic hydrogel particles with uniform anisotropic features, synthesized using double emulsions as templates, as reported by Adam Abate and co-workers on p.3201. Microfluidic assembly using flow-focusing double emulsion drop makers provides excellent control over the size, morphology, and monodispersity of the products. The particles exhibit excellent rotational control under an external field, with a possibility of eccentric rotation inducing a significant localized shear flow, and have promise for a variety of biomedical applications.
