(S)TEM structural and compositional nanoanalyses of chemically synthesized glutathione-shelled nanoparticles

This work is focused on the characterization by transmission and scanning–transmission electron microscopy-related techniques of core–shell nanoparticles synthesized via chemical methods. Diferent semiconducting, pure metallic or oxide materials have been utilized as the core (cadmium telluride, gol...
