Abstract

With the increasing necessity to synthesis nanoparticles in cheap and efficient methods and also sustain the environment, scientists keen on developing green based methods. Therefore, the present study demonstrated a cheap method to synthesize selenium nanoparticles (SeNP) based on bakery yeast and sodium hydrogen selenite only. The bakery yeast is cheap and abundant in any local market. So, the yeast can be found and applied in swift and easy manner during the experimental procedures that requires nano particle production. The resulted selenium nano-particles were verified by Means of multiple physical and chemical tests, namely Ultra-Violate Visible (UV-Visible) technique, Fourier transform infrared (FTIR) method, scanning electron microscopy (SEM) technique, and X-ray diffraction (XRD) device. The obtained scanning electron microscopy (SEM) results and Fourier transform infrared (FTIR) analysis respectively show 40-80 nm sized selenium nano-particles surrounded by preserving organic molecules. The external organic molecules help protecting and stabilizing the newly formed selenium nano-particles. The internal structure of SeNP was found to be amorphous as it was shown by the figures of the X-ray diffraction (XRD) test. In conclusion, the proposed method reduces the cost of manufacturing NP so that cheap experiments become achievable for researchers and costumers.
