Summary:

The synthesis of nanomaterials through more efficient methodologies is a topic of great interest worldwide. This work addresses the synthesis of AuNPs from an eco-friendly methodology that is governed by the principles of green chemistry, using low temperatures and selective plant extracts. The organic extracts of Agave (ethanolic, aqueous and hexanic) used have a high reducing power of the precursor ions, acting at the same time as stabilizers of the nanoparticles formed using low temperatures (65°C) and with short reaction times, in addition to be able to ensure the absence of toxic waste. The synthesis of the nanomaterials obtained is monitored by UV-VIS spectroscopy when the surface plasmon resonance signal corresponding to AuNPs is identified at λ= 540nm. The size of the synthesized NPs ranges between 10 and 60 nm depending on the extract. used, obtaining different morphologies which is verified in the images generated by transmission electron microscopy. As a result, this work explores a differential synthesis method that allows us to control morphology in addition to being efficient, fast, low cost, environmentally friendly and potentially scalable to larger volumes for the synthesis of Au nanoparticles.
