Phytotoxic and agro beneficial properties of antimicrobially efficient Sulfur nanoparticles (SNPs) and ZnO nanoparticles (ZNPs) were evaluated on Mung (Vigna radiata). Mung seeds were germinated with an increasing concentration gradient of nanoparticles. The extent of phtotoxicity were assessed depending upon the effect of used nanoparticles on physical factors (relative root and shoot length, dry weight and area of leaves), photosynthetic pigments (chlorophyll, carotene and xanthophyll content) and mitochondrial stress indicator level (thiol), A simultaneous study was undertaken to understand the effect of SNPs and ZNPs on overall plant growth and nutrition. The nutritive values of nanoparticles were determined in terms of total lipid and protein content. All the aforementioned biochemical assays were performed in triplicate for statistical viability.

“…Recently, great effort has been focused on finding approaches to synthesis sulfur nanoparticles (SNPs) with well-defined shapes and nano-sizes. Among these, reverse microemulsion (Guo et al, 2006;Desphande et al, 2008), an electrochemical (Shamsipur et al, 2011), water-in-oil microemulsion (Soleimani et al, 2013), an aqueous solution of potassium polysulfide and various organic and inorganic acids (Massalimov et al, 2012), ultrasonic technique (Xie et al, 2009), green solvents (Xie et al, 2012), surfactant assisted route (Chauhuri & Paria, 2010), supersaturated solvent (Wu et al, 2008), chemical precipitation (Meenatchi & Renuga, 2015), and membrane as natural biomaterial (Cheng et al, 2011). These methods have many disadvantages due to the difficulty of scale up the process, separation and purification of nanoparticles from the micro emulsions and energy requirements.…”

The objective of this research work is to synthesize sulfur nanoparticles by green route and to investigate the beneficial effect on root and shoot growth of tomato. Sulfur nanoparticles (SNPs) synthesized using aqueous extract of Ailanthus altissima leaves at room temperature. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) inspections indicated that nanoparticles are spherical and polydispersed with diameters ranging between 5 and 80 nm. The potential of sulfur nanoparticles for enhancing tomato's growth, increasing the concentration of sulfur nanoparticles from 100 ppm to 300 ppm cause an increase in root and shoot lengths, while higher concentration 400 ppm and 600 ppm induced an inhibitory effect. Results of this study reveal that SNPs have the potential to enhance root and shoot growth of tomato and the effect is concentration dependent.

“…Despite many exciting applications, there are only a few recent literatures available on synthesis of sulfur nanoparticles by different investigators [9][10][11][12] in both aqueous and microemulsion phase by different routes. Deshpande et al [9] have synthesized sulfur nanoparticles from H 2 S gas by using biodegradable iron chelate catalyst in reverse microemulsion technique.…”

“…They have also studied the antimicrobial activity of sulfur nanoparticles and shows it is very much effective, especially when the particle size is low. Guo et al [10] have prepared sulfur nanoparticles from sodium polysulfide by acid catalysis in reverse microemulsion technique. They found monoclinic or b-sulfur with an average particle size of around 20 nm.…”
