Analysis of metallic nanoparticles with an electron microscope

The task of the project is the study of metallic nanoparticles (both attached to the membranes of microorganisms and in solution) using electron microscopy methods from samples originating from bioleaching experiments conducted by the company BiotaTec OÜ. In the course of the work, preparations made from bioleaching test samples, including bacteria or nanocomplexes, are analyzed with an electron microscope using the negative contrast method. The size, shape and number of nanoparticles on the surface of bacterial cells will be analyzed. The work will be carried out in the transmission electron microscopy (TEM) laboratory of the Institute of Molecular and Cell Biology of the University of Tartu.
