Dr Eng. Paweł Karpiński from the Faculty of Chemistry at the Wrocław University of Science and Technology conducts advanced research on the behavior of gold nanoparticles. It uses the optical trapping method and the so-called optical vortices. The results of his work have been published in Advanced Optical Materials – one of the best journals on materials science and optics.
The scientist from Wroclaw University of Science and Technology is engaged in experimental research on the optical trapping of gold nanoparticles. He analyzes the movement and temperature of such “trapped” nanoparticles. For this purpose, it uses elongated gold nanoparticles, i.e. nanorods, which are trapped using a Laguerre-Gauss beam, the so-called optical vortices.
Such a measurement technique can be used in biology and medicine for the local measurement of temperature and viscoelastic properties in very small systems, e.g. inside a cell or other biological samples.
