Title: Optical tweezers: from space to the nanoscale… and back

Abstract:
Optical tweezers are powerful tools based on focused laser beams. They are able to trap, manipulate and investigate a wide range of micro and nanoscopic particles in different media, such as liquids, air, and vacuum. After an introduction to optical forces, I will give an overview of results on optical trapping and characterization of particles at the nanoscale. Furthermore, I will describe how optical tweezers can be used to trap and characterize extraterrestrial particulate matter.
