“…A certain volume of the extract is mixed with the appropriate amount of metal salt solution and the mixture is heated to the necessary temperature for the prescribed time under efficient mixing. To achieve the desired nanoparticles, optimization of every protocol is mandatory using different temperatures, solvents, pH conditions, extract concentrations and incubation times [ 60 , 61 ]. The reduction of metal ions to metal nanoparticles results in a color change of the solution, which can then be monitored by assessing UV-visible spectra.…”

“…In both of these approaches, the microorganism is spread onto the surface or inoculated into the growth medium. In the case of a well diffusion assay, a well is prepared in the medium and the tested nanoparticle solution is loaded into the well, while in the disc diffusion assay, the nanoparticle solution is loaded to a filter paper disc and then placed onto the surface of the inoculated medium [ 56 , 61 ]. The appearance of the inhibition zone around either the well or the filter disc indicates how effective the action of the nanoparticle is.…”

The nanomaterial industry generates gigantic quantities of metal-based nanomaterials for various technological and biomedical applications; however, concomitantly, it places a massive burden on the environment by utilizing toxic chemicals for the production process and leaving hazardous waste materials behind. Moreover, the employed, often unpleasant chemicals can affect the biocompatibility of the generated particles and severely restrict their application possibilities. On these grounds, green synthetic approaches have emerged, offering eco-friendly, sustainable, nature-derived alternative production methods, thus attenuating the ecological footprint of the nanomaterial industry. In the last decade, a plethora of biological materials has been tested to probe their suitability for nanomaterial synthesis. Although most of these approaches were successful, a large body of evidence indicates that the green material or entity used for the production would substantially define the physical and chemical properties and as a consequence, the biological activities of the obtained nanomaterials. The present review provides a comprehensive collection of the most recent green methodologies, surveys the major nanoparticle characterization techniques and screens the effects triggered by the obtained nanomaterials in various living systems to give an impression on the biomedical potential of green synthesized silver and gold nanoparticles.

Background: Sugarcane smut is a disease that is caused by the fungus Sporisorium scitamineum. This is a disease of economic importance in the sugarcane industry because it can cause losses of up to 50%. Current management practices have shown to be ineffective in controlling the fungal disease and hence there is a need for the development of antifungal agents that are biocompatible, non-toxic, environmentally friendly and easy to develop. Biosynthesized silver nanoparticles have been found to possess antimicrobial properties, and have not been explored in S. scitamineum. Results: The synthesis of silver nanoparticles using Carissa spinarum yielded particles that were spherical, smooth and had a size range from 3nm to 33nm in size. Optimization of the mixtures using ultraviolet-visual spectroscopy (UV-Vis) showed peaks in the range of 340nm to 450nm. The Fourier transform infrared spectroscopy analysis identified proteins to be essential capping agents and reducing sugars were responsible for the reduction of the silver nitrate to nanoparticles and stabilizing the nanoparticles. The biosynthesized silver nanoparticles had the highest antifungal activity at 5mg/ml, while the minimum inhibitory concentration and minimum fungal concentration were 78µg/ml. The in-vivo assays showed a significant (at P=0.05) reduction of the pathogen biomass concentration on the plants that were treated with the nanoparticles when compared to the control plants. The application of 58.5µg/ml of the b-AgNPs to the S. scitamineum resulted in a significant (P=0.05) increase in expression of the bE and bW genes, while the treatment with 39 µg/ml significantly (P=0.05) increased the expression of the bE gene, but had no significant (P=0.05) change in the expression of the bW gene. Conclusion: Silver nanoparticles that were synthesized successfully using C. spinarum crude extract inhibited the growth of S. scitamineum both in-vitro and in-vivo. The silver nanoparticles had a regulatory effect on the expression of the bE and bW genes in the fungus.
