Abstract

Au/Ag nanoparticles which absorb radiation near the infrared zone have been synthesized with the expectation that they will be employed in photothermal cancer diagnosis and treatment. The material exhibited two main morphologies, triangular shapes and nanostars, which in both cases presented two extra very bright peaks ending in a triangular face in a plane parallel to the electron beam direction. The particles have been characterized by weak beam dark field (WBDF) transmission electron microscopy, STEM-HAADF, SEM, and the composition was confirmed by point EDX analysis. HRTEM was used to analyze the defects observed in the microstructure.
