Gold nanoparticles (AuNPs) are one of the most remarkable nanomaterials. Due to their small size, these NPs can cross the blood–brain barrier making them good candidates for the treatment of diseases related to the central nervous system. The main objective of the present work was to evaluate the influence of surface charge on the biological behaviour of AuNPs by assessing the cytotoxic—viability and morphological alterations—and genotoxic—double strand breaks—effects induced in neuronal cells exposed to AuNPs with different charges: cationic, anionic, and neutral. Different toxicological behaviours were obtained depending on the surface charge of the NPs.
