This study reports on the biosynthesis of gold nanoparticles (AuNPs) using extracts from the psilocybin-producing mushroom Psilocybe cubensis and the evaluation of their neurostimulatory potential. The AuNPs were synthesized via the biological reduction of HAuCl\u2084 and characterized using UV-Vis spectroscopy, TEM, DLS, and FTIR. The physicochemical results confirmed the production of monodisperse spheroidal nanoparticles with an average diameter of 18.94 nm and high colloidal stability (zeta potential: &minus;31.0 mV). FTIR analysis suggested that fungal metabolites constitute the stabilizing organic corona of the nanomaterial. Bioactivity was evaluated in the Neuro2a (N2a) neuronal model using the IncuCyte\u00ae real-time monitoring platform and 3D holotomographic microscopy. A dose-dependent hormetic response was identified: concentrations between 22.91 and 183.25 \u00b5g\/mL induced a significant increase in cell proliferation and viability without morphological compromise, while doses \u2265 733.0 \u00b5g\/mL resulted in acute cytotoxicity. 3D holotomography confirmed that the biostimulatory treatment (91.63 \u00b5g\/mL) promotes a phenotype with active cytoplasmic extensions, consistent with early stages of neurite outgrowth. In conclusion, P. cubensis AuNPs constitute a promising nanotherapeutic system with neuroprotective and pro-proliferative capabilities, laying the groundwork for future applications in regenerative medicine and neurorehabilitation.<\/p>\n<p>Gold nanoparticles, Green synthesis, Holotomography, Neuroregeneration, Psilocybe cubensis.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Green nanotechnology applied to neuroscience offers innovative solutions for the treatment of central nervous system disorders.
