Within the available techniques for the synthesis of gold nanoparticles, the radiolytic synthesis allows proper control of the nucleation process without the need for reducing agents, in a single step, combined or not with simultaneous sterilization. This review details and summarizes the use of radiation technologies for the synthesis and preparation of gold nanoparticles concerning fundamental aspects, mechanism, current pathways for synthesis and radiation sources, as well as briefly outlines final applications and some toxicity aspects related to nanogold-based systems.openAccessgoldnanoparticlesgamma radiationelectron beamsx-ray sourcesradiolysisnanotechnologymedicinediagnostic usesionizing radiationsArtigo de periódico11810.3390/nano8110939aguardandohttps://orcid.org/0000-0002-1737-319167.4967.50
