Abstract
Selenium (Se) nanoparticles (SeNPs) express greater bioavailability, biocompatibility, and less toxicity than Se in ion form. SeNPs can be synthesized using different methods, including physics, chemistry, electrochemical plasma, and green synthesis using bacteria or plant extracts. In this study, the SeNPs were synthesized using a combination of Smilax glabra (SG) root extract as a reducing and stabilizing agent combined with electrochemical plasma (PLS), and their biological activities were examined for the first time. The obtained results showed that the SeNPs (SG+PLS) were successfully fabricated in a spherical shape with a size in the range of < 100 nm and maximal specific absorption spectrum at 310 nm. The SeNPs showed a free radical scavenging effect up to 94 % at a concentration of 125 µg/mL. Moreover, it expressed higher O2- radical scavenging activity compared to the SeNPs (SG) and SeNPs (PLS) alone at the test concentrations of 12.5, 25, and 125 µg/mL. The SeNPs also exhibited better antibacterial activity against E. coli, Staphylococcus aureus, and Candida albicans than those of SeNPs (SG) and SeNPs (PLS). Thus, one-step synthesized SeNPs (SG+PLS) with augmented biological activities had potential applications in foods and cosmetics.
期刊介绍:
Nano-Structures & Nano-Objects is a new journal devoted to all aspects of the synthesis and the properties of this new flourishing domain. The journal is devoted to novel architectures at the nano-level with an emphasis on new synthesis and characterization methods. The journal is focused on the objects rather than on their applications. However, the research for new applications of original nano-structures & nano-objects in various fields such as nano-electronics, energy conversion, catalysis, drug delivery and nano-medicine is also welcome. The scope of Nano-Structures & Nano-Objects involves: -Metal and alloy nanoparticles with complex nanostructures such as shape control, core-shell and dumbells -Oxide nanoparticles and nanostructures, with complex oxide/metal, oxide/surface and oxide /organic interfaces -Inorganic semi-conducting nanoparticles (quantum dots) with an emphasis on new phases, structures, shapes and complexity -Nanostructures involving molecular inorganic species such as nanoparticles of coordination compounds, molecular magnets, spin transition nanoparticles etc. or organic nano-objects, in particular for molecular electronics -Nanostructured materials such as nano-MOFs and nano-zeolites -Hetero-junctions between molecules and nano-objects, between different nano-objects & nanostructures or between nano-objects & nanostructures and surfaces -Methods of characterization specific of the nano size or adapted for the nano size such as X-ray and neutron scattering, light scattering, NMR, Raman, Plasmonics, near field microscopies, various TEM and SEM techniques, magnetic studies, etc .
