"Forces and torques at the nanoscale: From measurement to application"

Forces and torques at the nanoscale:
From measurement to application

Giovanni Volpe
Bilkent University, Ankara, Turkey


The possibility of measuring microscopic forces down to the
femtonewton range has opened new possibilities in fields such as
biophysics and nanophotonics. In this seminar, I will review some
of the techniques most often employed, namely the photonic force
microscope (PFM) and the total internal reflection microscope (TIRM).
I will particularly focus on the measurement of radiation forces
generated by surface plasmons, on the extention of the PFM technique
to the measurement of mechanical torques, and on a new calibration
method for TIRM that allows one to adopt it in front of reflective
surfaces (gold coating).
