Synthesis and Stabilization of Gold Nanoparticles in Castor Oil [Síntese e Estabiliza o de Nanopartículas de Ouro em óleo de Mamona]

In this manuscript we show some examples of the scientific literature about formation of hybrid organic-inorganic colloids based on vegetable oils as stabilizing and dispersing agents of metal nanoparticles (or salts). These systems display a strong Green Chemistry link, since a matrix of vegetable oil-based, being an organic, renewable, and non toxic medium, allows the development of new devices that can be applied in biomedical and environmental areas. We also show some of our main results related to the synthesis of stable colloidal castor oil-based systems containing gold nanoparticles dispersed into them.
