The optical forces originated from the exchange of photon momentum, as well as optical traps formed by a restoring optical force field, have allowed for gentle and precise manipulation of micro- and nanoparticles. The optical trapping technique shared the Nobel Prize in Physics in 2018 particularly for its innumerous applications in the broad field of biophotonics. The Optical Forces, Trapping, Manipulation and Related Applications Workshop is open to all topics related to novel methods of the formation of optical forces and traps, the realization of new functionalities such as particle sorting and optofluidics, single particle and single molecule characterizations, as well as applications in biology and other fields.
Topics may include, but are not limited to:
Optical forces and trapping;
Optical manipulations;
Holographic optical tweezers;
Near field optical trapping techniques;
Beam shaping and optical trapping;
3D microscopy and micromanipulations;
Light-matter momentum exchange;
Optical potential wells;
Single molecule biology;
Angular optical tweezers;
Optofluidics.
