Abstract
The present study aimed to synthesize selenium nanoparticles (SeNPs) using aqueous extract of black currant as a reducing agent. The green synthesized black currant selenium nanoparticles (BCSeNPs) were identified by color change. The characterization of SeNPs was achieved by Ultraviolet-visible (UV–VIS) spectroscopy, scanning electron microscopy (SEM), X–ray diffraction analysis (XRD), and Fourier transform infrared spectroscopy (FTIR). These tests were used to detect: stability, morphology, size, crystalline nature, and functional groups present on the surface of BCSeNPs. The results revealed appearance of the brick-red color indicating the specific color of selenium nanoparticles, and UV-Vis spectroscopy showed band absorbance at 265 nm of intense surface plasmon resonance manifesting the formation and stability of the prepared BCSeNPs. The SEM image showed the prevalence of spherical selenium nanosized, XRD at 2θ revealed crystallin selenium nanoparticles, the size was in the average of 18-50 nm. Furthermore, FTIR revealed the presence of functional groups of the plant which act as stabilizing and reducing agents. In conclusion, the aqueous black currant extract can act as a reducing and capping agent to synthesize BCSeNPs in nano-scale size by a simple method

Introduction as well as carboxy methyl cellulose [8, 9]
The color change upon the addition of selenium selenite to the black currant extract was considered as an indication of selenium nanoparticles (SeNPs) synthesis [36]
The bio-reduction property of black currants in the synthesis of SeNPs was investigated by Ultraviolet–visible spectroscopy (UV-VIS) spectrum, which is a significant technique to authenticate the stability and formation of black currant selenium nanoparticles (BCSeNPs) in the solution
Summary
Introduction as well as carboxy methyl cellulose [8, 9]. Besides, Nanotechnology sciences allow to improve the experimental practice of the nanoscale constituent’s preparation with exceptional possessions [1]. SeNPs could be chemically [4] or physically [5] synthesized. It can even be obtained by the biological way, using microorganisms or extracts of different plants [6, 7]. Synthesized SeNPs were prepared by reduction of the selenious acid solution using ascorbic acid in the presence of polysaccharides such as acacia gum; glucomannan. Many disadvantages due to using chemical or physical methods of SeNPs have been identified, such as extreme temperature, high pH, environmental pollution, as well as they are very expensive methods [20, 21]. On the contrary, using plant extract (green method) for biosynthesis of
