Chemistry and Biochemistry Announces Annual Celebration of Student Achievement
The Seventeenth Annual Department of Chemistry and Biochemistry’s Celebration of Student Achievement will be held on Wednesday, April 10, 2019. The celebration begins at 3:30 p.m. in the Kiva at the Kent Student Center with a plenary lecture entitled “Dynamic Droplets” from Dr. Timothy M. Swager, John D. MacArthur Professor of Chemistry, Massachusetts Institute of Technology.
This lecture will focus on the design of systems wherein reconfiguration of complex liquid emulsions (droplets) can be triggered chemically or biochemically. The utility of these methods is to generate new transduction mechanisms by which chemical and biological sensors can be developed. Complex liquid droplets behave as optical lens systems and small changes in surface tensions can change focal lengths or cause systems to switch between optically transmissive or scattering states. Central to this scheme is that the fluids in the droplets have different densities and hence are aligned by the earth’s gravity. The induced optical changes can be triggered with chemical, photochemical, or biochemical stimuli and thereby create new generations of sensors. Demonstrations of these methods for the detection of enzyme concentrations and pathogens will be presented.
The plenary lecture is open to the public and no registration is required.
A reception follows the lecture at 4:45 p.m. in the North Commons of the Integrated Sciences Building, and the awards and scholarship recognition ceremony for chemistry majors begins at 5:15 p.m.
