Artigo IPEN-doc 25206 An overview of the synthesis of gold nanoparticles using radiation technologies2018 - FREITAS, LUCAS F. de; VARCA, GUSTAVO H.C.; BATISTA, JORGE G. dos S.; LUGAO, ADEMAR B.At a nano-level, optical properties of gold are unique and gave birth to an emerging platform of nanogold-based systems for diverse applications, because gold nanoparticle properties are tunable as a function of size and shape. 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.Artigo IPEN-doc 21177 Síntese de nanoparticulas de ouro estabilizadas por quitosana2015 - GERALDES, ADRIANA N.; OLIVEIRA, MARIA J.A.; SILVA, ANDRESSA A. da; LEAL, JESSICA; BATISTA, JORGE G.S.; LUGAO, ADEMAR B.Resumo IPEN-doc 20574 Evaluation of physico-chemical properties and biodegradation of polymeric membranes based chitosana, starch and polyvinylpyrrolidone (PVP) synthesized by gamma radiation at different dose rates2014 - BATISTA, JORGE G. dos S.; FONSECA, ANA C.M.; LUGAO, ADEMAR B.Resumo IPEN-doc 20575 Influence of gamma radiation on the release of the controlled drug polymer matrix2014 - BATISTA, JORGE G. dos S.; VRECHI, TALITA A. de M.; LUGAO, ADEMAR B.Resumo IPEN-doc 20492 Influência da radiação gama na densidade de reticulação e liberação de fármacos em matrizes poliméricas2014 - BATISTA, J.G.S.; LUGAO, A.B.; FONSECA, A.C.M.; LIMA, N.B.
