Engineering Nanoparticle Assembly Processes

Michael Bevan's research on designing, controlling, and optimizing colloidal self- and directed- assembly processes is pushing the envelope of science.

This line of research is directed at the development of highly integrated technologies in microdevices, with enhanced and novel functionality at the scales of individual molecules, that impact a variety of areas, including environmental and energy applications, individualized diagnostics and medicine, and fundamental studies. Joelle Frechette is working on creating microfluidic tools for particle separation, emulsification, and environmental remediation, and she also is developing surfaces patterns with tunable wettability that can serve as a platform for colloidal assembly. David Gracias’ laboratory is focused on transforming lithographically micro- and nanopatterned planar thin films to 3D devices for applications in electronics, optics and medicine. Zachary Gagnon’s work focuses on studying and utilizing micron-sized electric fields generated within custom-fabricated microdevices to separate, characterize and manipulate biological fluid and bioparticles. Marc Donohue is developing a new theory to explain why diffusion does not follow Fick’s Law in nanomaterials. Chao Wang’s efforts focus on the inorganic nanomaterials for heterogeneous catalysis and energy conversion and storage applications.

Konstantinos Konstantopoulos fabricates novel microfluidic devices to measure cellular traction forces and study the mechanisms of cell migration through physically constricted microenvironments.
Rebecca Schulman‘s laboratory builds self-assembling biomolecular nanostructures and nanomaterials that can adapt to their environment and reconfigure. The group is focused on understanding fundamental design questions about how to build self-healing and self-replicating materials, or self-wiring circuits. Applied research is focused on the design of next-generation biomechanosensors and bioelectronics.
Chao Wang
Chao Wang’s group is developing advanced nanomaterials, including magnetic, semiconductor and plasmonic materials, by solution synthesis and processing for biomedical imaging and diagnostics.
