Among diverse non-metal nanoparticles (NPs), sulfur nanoparticles (SNPs) are one of the most significant and intriguing nanomaterials. An important concern about the synthesis of SNPs is the formation of hazardous wastes, noxious by-products and ruinous pollutants. The best solution to mitigate and/or exclude these noxious substances are plant mediated biosynthesis of SNPs. Eco-benevolent SNPs from plant extracts have been identified as precious nanomaterial in various agricultural, biomedical and catalytic applications including lithium-sulfur batteries, pesticides, fungicides, carbon nanotube modification, gas sensor and neutron capture in cancer therapy because of their splendid performance and selectivity. They have captured the consideration of researchers owing to their sustainable, economical, non-noxious, convenient, green and eco-benevolent nature. This review attempts to cover the recent advancements in the biosynthesis, characterization techniques and applications of biogenic SNPs in environmental and biomedical systems. Furthermore, the stability of biosynthesized SNPs and mechanism of their formation are briefly discussed.
Noval Approach For Synthesis Sulfur (S-NPs) Nanoparticles Using Albizia Julibrissin Fruits Extract
Advanced Materials Letters, 2015
Sulfur nanoparticles have been successfully prepared from sodium thiosulfate in the presence of Albizia julibrissin fruits extract at room temperature. The resulting sulfur nanoparticles were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). XRD characterizes the final product as highly crystalline sulfur, exhibited high purity, spherical shape with average particle size of about 20 nm, and particle size distribution in range 10 nm to 100 nm. The particle size of nanoparticles could be controlled by tuning the amount of Albizia julibrissin fruits extract. FT-IR analysis of S-NPs indicated a new chemistry linkage on the surface of sulfur nanoparticles. This suggests that Albizia julibrissin fruits extract can bind to sulfur nanoparticles through carbonyl of the amino acid residues in the protein of the extracts, therefore acting as stabilizer and dispersing agent for synthesized sulfur nanoparticles. This research provides a greener and more environment-friendly synthetic method for the production of sulfur nanoparticles for antibacterial and antifungal activities.

Journal of Agricultural Science, 2015
The major objective of this research paper is to synthesis sulfur nanoparticles (SNPs) by green route, which can improve plant's growth and reduce the environmental pathogens. Sulfur nanoparticles (SNPs) were synthesized by a simple green procedure using Melia azedarach leaves aqueous extract and citric acid. The leaves of Melia azedarach aqueous extract act as a capping and stabilizing agent in the formation of sulfur nanoparticles. The synthesized sulfur nanoparticles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FT-IR). The average particles diameter size was found to be 20 ± 4 nm. Analysis showed that the nanoparticles are crystalline in nature, with spherical shape. A preliminary field study was conducted to evaluate growth and development of Cucurbita pepo in response to sulfur nanoparticles.

We report new, eco-friendly and green method for the synthesis of sulphur nanoparticles using sodium polysulphide in the presence of leaf extracts of four different medicinal plants, which can be used for treatment of bacterial infections. Sodium polysulphide and acidic solution (H 2 SO 4) in the presence of plant leaf extract developed the yellowish precipitate in solution, which indicated the formation of sulphur nanoparticles. UV-Vis spectrophotometer analysis of reaction mixture showed absorbance spectra in the range of 292-296 nm, which is supposed to be specific for sulphur nanoparticles. Zeta potential study of sulphur nanoparticles synthesized from Catharanthus roseus showed more stability when compared with other medicinal plants. Sulphur nanoparticles synthesized from C. roseus were further characterized by XRD analysis, FTIR analysis, and TEM analysis. The biogenic sulphur nanoparticles were spherical, polydispersed with particle size of 70-80 nm. Evaluation of antibacterial study revealed that synthesized sulphur nanoparticles exhibited better bactericidal efficacy against common pathogenic bacteria Escherichia coli and Staphylococcus aureus with minimum inhibitory concentration of 200 μg/ml with significant activity used in combination with antibiotic. It can be concluded that the synthesized sulphur nanoparticles can be used as antibacterial agents after thorough experimental trials in animals.

Critical Reviews in Environmental Science and Technology, 2020
Recently, interest in sulfur nanoparticles (SNPs) and their applications in food, agriculture, and biomedical fields have increased mainly due to the significant antibacterial and anticancer activity of these nanomaterials. However, with these applications, there is a growing concern regarding the biological effects and the possible risks to the environment and health by the use of sulfur nanoparticles. In this regard, recent research has been published based on the investigation of the potential effects of SNPs on plant and animal cells. However, little is known about the mechanism of action of SNPs on other microorganisms and human cells.

Elemental sulfur has been used for a long time to treat superficial mycoses in both medical and veterinary practices, but effective treatment requires high concentrations of sulfur. Encapsulation of sulfur in nanoparticles can potentially allow the delivery of high concentrations of sulfur to infections. Sulfur nanoparticles were synthesized from Catharanthus roseus extract and sodium sulfide at various pH conditions (4, 6, and 7). Particle identification and characterizations were performed by X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), and dynamic light scattering analysis. Broth microdilution and time-kill assays were used to determine the antifungal effect against Microsporum canis DMST29297. The X-RD analysis showed that the fine yellow powder of sulfur nanoparticles contained α-orthorhombic sulfur and SEM showed a uniform distribution and similarity in size of almost spherical particles.
