2:30 pm:
Biophysics Seminar in 110 PAN
Speaker: Dr. Frank Vollmer,Max Planck Institute for the Science of Light, Erlangen, Germany
Subject: Advances in Biodetection with Optical and Mechanical Microresonators

Dr. Frank Vollmer will present his results on advancing chip-scale
biosensing capabilities with optical and mechanical microresonators.
In the optical domain, he has developed a microcavity biosensing
platform that is capable of monitoring single DNA molecules and
their interaction kinetics, hence achieving an unprecedented
sensitivity for label-free detection with light. In the mechanical
domain, he is developing a new force-based biosensing technique
based on the quartz crystal microbalance. By applying centrifugal
forces to a sample, it is possible to repeatedly and
non-destructively interrogate its mechanical properties in situ and
in real time.
