Colloquium: November 6, 2013
Dynamics and spectroscopy of optically trapped microparticles
|November 6, 2013 Wednesday||16:00||EE01|
ABSTRACT — The seminar will consist into two parts. In the first part it will discuss the use of optical tweezers to study at mesoscopic scales the mechanical behavior of several class of soft materials, including biological samples (microrheology). The second part will be focused on several spectroscopic techniques and their use in the study of single particle or cells. It will shown how Raman spectroscopy can be combined with optical tweezers and how the low efficiency of the Raman yield can be overcame thanks to single molecule sensitive techniques based on localized surface plasmon resonances (Surface-Enhanced Raman Scattering , SERS).
