“…The excitation peak is at ≈399 nm (Figure 12a) while the emission peak is located at ≈599 nm (Figure 12b), [176] in good accordance with other works of literature. [177,178] The excitation result was consistent with λ max of the reaction medium at 400 nm, and the peak at 599 nm in the emission spectrum could be due to the formation of Se particles.

Investigations into semiconductor nanomaterials from both an academic and industrial point of view are of great significance. Selenium (Se) nanostructures, as narrow bandgap semiconductors, have a variety of potential applications in the fabrication of many high-performance devices. The past decades have witnessed rapid development in new strategies for synthesizing Se nanostructures with controlled sizes, shapes, and structures, whose diverse structure-dependent nature enables functional Se nanomaterials to have great potentials for modern applications. This review focuses on the synthesis and morphology control of intriguing Se nanostructures, the latest progress in understanding the fundamental properties of Se nanostructures, and the recent advances in high-performance Se nanomaterial-based devices for diverse applications. Finally, the challenges and future opportunities for Se nanostructures and Se-related devices are also discussed.

Nanotechnology has the potential to revolutionize a number of research fields, including biomedicine. Currently, the fabrication of biocompatible nanomaterials is of high interest worldwide. Little is known about the possible synthetic routes to fabricate selenium nanoparticles. In this research, we focused on the potential of a medicinally important plant species, garlic (Allium sativum), for the green synthesis of selenium nanoparticles. The garlic aqueous extracts acted as a capping and reducing agent in forming selenium nanoparticles. Green-synthesized selenium nanoparticles were characterized using UV-vis spectrophotometry, TEM, SEM, EDAX, FTIR and XRD analysis. Furthermore, green-fabricated and conventional chemically synthesized selenium nanoparticles were tested to evaluate their cytotoxicity against Vero cells. CC 50 values revealed that biologically synthesized selenium nanoparticles showed eco-friendly features and limited cytotoxicity if compared with chemically synthesized selenium nanoparticles.

“…Researchers used glucose as a reducing agent and stabilizer of SeNPs; however, in their synthesis they used high temperatures and toxic solvents. 35,36 Therefore, we chose D-fructose because it is a plentiful and cheap reducing sugar to act as a reducing agent for sodium selenite in clean and quick synthesis of SeNPs using water as solvent and at low temperature. The obtained nanoparticles were tested for cytotoxicity against normal cells (fibroblasts-P4) and uterine sarcomas cells (MES-SA and MES-SA/Dx5) in order to assess their potential use as an anticancer drug.…”

“…The use of sugars as reducing agents to obtain such nanoparticles has been investigated. [34][35][36] Glucose and fructose have aldehyde and hydroxyl groups at carbon 1, respectively, which make them effective reducing agents. Researchers used glucose as a reducing agent and stabilizer of SeNPs; however, in their synthesis they used high temperatures and toxic solvents.…”

We present an environment friendly synthesis of selenium nanoparticles and the study of their cytotoxic activity against uterine sarcoma cancer and fibroblasts cells. Amorphous selenium (a-SeNPs) and trigonal selenium (t-SeNPs) were synthesized using D-fructose as the reducing agent and characterized by high-resolution transmission electron microscopy (HRTEM), energydispersive X-ray spectroscopy (EDX), powder X-ray diffraction analysis (XRD), inductively coupled plasma optical emission spectrometry (ICP OES), dynamic light scattering (DLS) to obtain zeta potential values and cyclic voltammetry (CV). Particularly, a-SeNPs presented high toxicity toward the resistant cancer cell line MES-SA/Dx5 and its parental MES-SA line. However, they are not toxic against P4 fibroblast cells in comparative studies. Keywords: selenium nanoparticles, D-fructose, cancer cells, green chemistry, cytotoxicity IntroductionSelenium is an essential element of significant importance not only for humans, but also for other forms of life. 1,2 Inorganic seleno-compounds have strong antioxidant activity, as well as some pro-oxidant effects and, additionally, have great importance in nutrition and medicine. 3,4 Epidemiological studies have already demonstrated the potential role of selenium in the prevention and treatment of cancer cells. [5][6][7] For example, selenium supplementation showed effective reduction in the incidence of cancer in the cervix, lung and liver. 8 However, the biological activity of elemental selenium stands opposite to the selenium salts, since selenite and selenate showed inadequate cytotoxicity to normal cells. [9][10][11] In this sense, nanoparticles of elemental selenium stand out as an alternative, due to its low toxicity and acceptable bioavailability. [12][13][14] Nanoparticles have become increasingly prominent in the medical field in the last few decades, giving rise to a new area, nanomedicine. This new area is focused on developing nanomaterials with potential use in therapy and diagnosis of diseases, [15][16][17] including selenium nanoparticles (SeNPs). 18Generally, the methods for obtaining SeNPs involve multiple steps, high temperatures and pressures; require expensive equipment and reagents, as well as being harmful to the environment. [19][20][21][22][23][24][25][26][27] In this sense, it is necessary to develop simple routes that focus on green chemistry and no harm to the environment. Research has demonstrated the use of microorganisms such as bacteria, to reduce selenite. This method is considered a clean synthesis, but the cost and time of preparation of microbiological cultures is a disadvantage. 28-30The use of plant extracts and biopolymers such as chitosan, konjac glucomannan, gum acacia, carboxymethyl cellulose, sodium alginate and glutathione, as reducing agents of selenite has also been an alternative, since they are highly biodegradable and non-toxic materials. However, in each of these works there are several processing steps "Sweet Chemistry": a Green Way for Obtaining Selenium Nanop...
