| Phil Nelson, University of Pennsylvania Colloquium 4:45 p.m. Physics Lecture Hall Tethered particle motion (TPM) is an experimental technique to monitor conformational changes in single molecules of DNA in real time, by observing the position fluctuations of a micrometer-size bead attached to the DNA. I'll present some recent work on theoretical problems inherent in the interpretation of TPM experiments, both in equilibrium and dynamical aspects. Graphic: attached.
