Spherical catalytic micromotors fabricated as described in Wheat et al. [Langmuir 26, 13052 (2010)] show fuel concentration dependent translational and rotational velocity. The motors possess short-time and long-time diffusivities that scale with the translational and rotational velocity with respect to fuel concentration. The short-time diffusivities are two to three orders of magnitude larger than the… Read more »

In this work, we introduce a simple solvent-assisted micromolding technique for the fabrication of high-fidelity styrene-ethylene/butylene-styrene (SEBS) microfluidic devices with high polystyrene (PS) content (42 wt% PS, SEBS42). SEBS triblock copolymers are styrenic thermoplastic elastomers that exhibit both glassy thermoplastic and elastomeric properties resulting from their respective hard PS and rubbery ethylene/butylene segments. The PS… Read more »

Carbon nanotubes (CNTs) have one of the highest production volumes among carbonaceous engineered nanoparticles (ENPs) worldwide and are have potential uses in applications including biomedicine, nanocomposites, and energy conversion. However, CNTs possible widespread usage and associated likelihood for biological exposures have driven concerns regarding their nanotoxicity and ecological impact. In this work, we probe the… Read more »

William Walker’s image of a liposome and its interaction with engineered nanomaterials was selected as the cover image of the journal Langmuir.  Babak Moghadam’s work was featured on the cover.  Congrats William.  

Steve worked with Jaime Raben and Pavlos Vlachos to show that using robust phase correlation improves the accuracy of determining particle displacement over cross-correlation and confocal imaging.

Babak Moghadam,Wen-Che Hou, and Charlie Corredor coauthored a paper on the disruption of artificial cell membranes by engineered nano particles. The article is published in Langmuir and will appear in print in August and can be viewed here.
