Abstract: Contaminated ballast water can pollute fresh waters. Selenium (Se) is an essential trace mineral with various biological effects. Different physico-chemical and biological methods have been reported in literature for selenium nanoparticles (SeNPs) synthesis. The aim of this study was to use the parsley (Petroselinum crispum) leaves extract in order to prepare SeNPs by an eco-friendly method. SeNPs were characterized from structural and morphological point of view by using analytical techniques such as: dynamic light scattering (DLS), UV-Vis spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR) and Atomic Force Microscopy (AFM). DLS method revealed particles with maximum distribution being registered around 400 nm and an apparent zeta potential value of -14.2 mV. On the other hand, the parsley leaves extract was characterized concerning the total phenols content, vitamin C and antioxidant capacity, in order to evidence potential properties as biocatalyst or natural stabilizers for SeNPs synthesis. This study reports for the first time a green approach for SeNPs biosynthesis by using parsley leaves extracts.
