Fig. 2: Synthesis and characterization of molecular engineered SeMNPs.

A Preparation routes of SeMNPs using oxidative polymerization. B UV-Vis spectra of SeMNPs and eumelanin nanoparticles (NPs). ε: molar absorption coefficient. C XPS Se 3 d spectra of SeMNPs. D High-angle annular dark-field imaging (HAADF) images of SeMNPs superimposed with the elemental mappings of Selenium (purple), Nitrogen (green) and Carbon (blue). Representative images are presented.
