MRSEC researchers working in an international collaboration with French scientists at ESPCI (Paris Tech) have discovered that rocket-shaped metallic micro-rods can be propelled through fluids using ultrasound, with fast translation towards the tapered end and rapid rotation & assembly of rods into circular chains that move like conveyer belts. Since most ways to make micro-objects move auto
Objective: Use plasmon-enhanced photochemical reactions to map the polarization-dependent near fields of optical antennas. Approach: Use the anisotropic nano-crescent structure and SU-8 photo-resist. SU-8 exposure accomplished through plasmon-enhanced multi-photon absorption by 800 nm light.

Hydrogels are used as scaffolds for tissue engineering, vehicles for drug delivery, actuators for optics and fluidics, and model extracellular matrices for biological studies. The scope of hydrogel applications, however, is often severely limited by their mechanical behaviors. Most hydrogels are brittle, sensitive to
The outstanding electronic and mechanical properties of single-atom-thick layers of carbon, so-called “graphene” films, make
