摘要：This research aimed to synthesize, characterize and compare the formation of silver nanoparticles in Curcuma longa and Anacardium occidentale. The hydroalcoholic solutions were prepared with 200g of curcumin powder and cashew leaves respectively, mixed with 70% alcohol, to obtain the nanoparticles, it used 1.0mmol / L silver nitrate, 1% sodium citrate and added the curcumin extract. and the cashew leaf extract, separately. The nanoparticles were characterized by infrared spectroscopy in a beam with a wavelength between 250 and 800nm. It was verified by means of the absorption peak attributed to Plasmonic Surface Resonance (SPR) that both the curcumin extract and the cashew extract were able to synthesize and stabilize the silver nanoparticles with spherical shapes and approximately 20nm in size. The two plant extracts used were shown to be efficient in the development and stabilization of silver nanoparticles by means of green synthesis.
