Solid State Nanopores as Nanoscale Detectors: Single Molecules, Fast Kinetics, and Ionic Liquids

Promotional image for talk: Elements of a successful scientific talk

Speaker(s): David Hoogerheide

The advent of nanotechnology has created new possibilities for understanding the world and developing technologies to shape it. Nanoscale devices are useful for studying the behavior of very small numbers of molecules; because of their small size, however, nanodevices are particularly sensitive to fluctuations. One such device is the solid state nanopore, which is a promising platform for next-generation DNA sequencing strategies. I will discuss how the sensitivity of nanopores can be used to study a variety of physical processes, including the motion of DNA and other ions. I will also propose to use the solid state nanopore to study ionic liquids, a fascinating class of organic compounds that are molten at room temperature and behave as very concentrated, solvent-less electrolytes. These compounds are likely to play an important role in the energy technologies of the future, especially as catalysts for energy conversion and as battery electrolytes.

Colloquium

Junior and senior physics majors attend our biweekly colloquium series, held on Tuesday afternoons at 4:30 p.m. in Shanahan B460. The talks are open to all students and to the public, and are frequently attended by scientists from the other Claremont Colleges, Cal Poly Pomona, and others. The series features speakers from a broad range of institutions and fields of physics.
