selenium nanoparticles (SeNPs) have a great deal of interests because of their specific biological, chemical, medicinal and pharmaceuticals properties. SeNPs exhibit potential as therapeutic agents and drug carriers, as well as excellent bioavailability and low toxicity. As a rule of green synthesis of SeNPs, toxic and hazardous substances that are involved in reactions should be eliminated or reduced as much as possible. Using plants for NP synthesis can be advantageous over other biological processes because it eliminates the elaborate process of maintaining cell cultures and can also be suitably scaled up for large-scale NP synthesis. In this paper, green synthesis of selenium nanoparticles using garlic extract through microwave and ultrasound method was performed. UV analysis was performed with UV-Vis spectra for the synthesized Se NPs. According to the results, no peak was observed in the range of selenium nanoparticles synthesized by sonication, but synthesis of SeNPs using microwave technique at 321 nm had the highest adsorption, The nanoparticles synthesized using microwave appear to have smaller particle size than the sonication technique. The sonication technique seems to be unable to provide the appropriate temperature for the synthesis of SeNPs, so the microwave technique, which is a fast and temperature-sensitive technique, was chosen for the synthesis of SeNPs.
