Project Description

This project focuses on the synthesis of Ytterbium doped NaYF4 nanoparticles and their application in optical tweezers (in cooperation with AK Schäffer). In these optical tweezers, the nanoparticles are held three-dimensionally in a laser focus, which allows us to manipulate individual molecules in a targeted manner. Previous systems made of metallic nanoparticles are not suitable for use in living cells due to a laser-induced temperature increase. In addition, the optical trap is destabilized by the thermal motion of the particles. Therefore, the goal is to use NaYF4:Yb nanoparticles to bypass the previous limitations in order to use the particles in living cells and further increase the resolution by reducing the size of the nanoparticles.
