Nanoparticles encased in oily liquid shells can bind together

Researchers found that magnetic nanoparticles encased in oily liquid shells can bind together in water to form flexible chains. The oil wets the particles and creates capillary bridges between them so that the particles stick together on contact. A magnetic field is added to arrange the nanoparticle chains and provide directionality.

[Research supported by U.S. National Science Foundation grant DMR 1121107.]
