The optical tweezers were awarded the Nobel Prize twice for the important contributions to the field of laser cooling and biophotonics. With the development of nanotechnology, research into nanoparticle trapping is now becoming even more important. The two main challenges for nanoparticles trapping are:

1. The sub-60 nm nanoparticles cannot trap stable.

2. The low refractive index sub-60 nm nanoparticles cannot be detected by PSD.

My research is focused on solving these two challenges.

1. Research on lanthanide ions doping upconversion nanoparticles enhances the trap stiffness.

2.Research on video tracking methods to extract localization from video.
