Abstract Green synthesis methods are environmentally friendly, cost effective and nonhazardous for biomedical applications in comparison with other methods. The aim of the study was green synthesis of silver nanoparticles using medicinal animal dung extract as a reducing, capping and stabilizing agent for the first time among other synthesis methods of silver nanoparticles. Female donkey’s dung was capable to reduce silver ions to nanoparticles and stabilize them. Silver nanoparticles with average sizes of 36 nm were synthesized and characterized by UV-Vis, FT-IR, XRD and TEM. Moreover, synthesized nanoparticles were analyzed in terms of anticancer activity by MTT assay on MCF-7 cell line. UV–Visible spectrophotometer showed an absorbance peak in the range of 414-433 nm. To identify the phytochemical coating of particles, FTIR analysis was used. Transmission electron microscope (TEM) images and X-ray diffraction (XRD) confirmed the formation of small spherical silver nanoparticles. The MTT assay revealed potent anticancer effects of the aqueous extract synthesized nanoparticles on MCF-7 cells, incubated for 24 hours. Based on the current findings, it is strongly believing that the use of donkey’s dung offers large scale production of biocompatible silver nanoparticles that can be suggested to possess valuable anticancer agents against breast cancer cell lines.

The increasing number of multi-drug-resistant bacteria and cancer cases, that are a real threat to humankind, forces research world to develop new weapons to deal with it. Biogenic silver nanoparticles (AgNPs) are considered as a solution to this problem. Biosynthesis of AgNPs is regarded as a green, eco-friendly, low-priced process that provides small and biocompatible nanostructures with antimicrobial and anticancer activities and potential application in medicine. The biocompatibility of these nanoparticles is related to the coating with biomolecules of natural origin. The synthesis of AgNPs from actinobacterial strain was confirmed using UV-Vis spectroscopy while their morphology, crystalline structure, stability, and coating were characterized using, transmission electron microscopy (TEM), X-ray diffraction (XRD), Zeta potential and Fourier transform infrared spectroscopy (FTIR). Antibacterial activity of biogenic AgNPs was evaluated by determination of minimum inhibitory and minimum biocidal concentrations (MIC and MBC) against Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Staphylococcus aureus. The potential mechanism of antibacterial action of AgNPs was determined by measurement of ATP level. Since the use of AgNPs in biomedical applications depend on their safety, the in vitro cytotoxicity of biosynthesized AgNPs on MCF-7 human breast cancer cell line and murine macrophage cell line RAW 264.7 using MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] assay, cell lactate dehydrogenase (LDH) release and measurement of reactive oxygen species (ROS) level were assessed. The nanoparticle protein capping agent that can be involved in reduction of silver ions to AgNPs and their stabilization was identified using LC-MS/MS. Nanoparticles were spherical in shape, small in size (mean 13.2 nm), showed crystalline nature, good stability (−18.7 mV) and presence of capping agents. They exhibited antibacterial activity (MIC of 8–128 μg ml−1, MBC of 64–256 μg ml−1) and significantly decreased ATP levels in bacterial cells after treatment with different concentrations of AgNPs. The in vitro analysis showed that the AgNPs demonstrated dose-dependent cytotoxicity against RAW 264.7 macrophages and MCF-7 breast cancer cells but higher against the latter than the former. Cell viability decrease was found to be 42.2–14.2 and 38.0–15.5% while LDH leakage 14.6–42.7% and 19.0–45.0%, respectively. IC50 values calculated for MTT assay was found to be 16.3 and 12.0 μg ml−1 and for LDH assay 102.3 and 76.2 μg ml−1, respectively. Moreover, MCF-7 cells released a greater amount of ROS than RAW 264.7 macrophages during stimulation with all tested concentrations of AgNPs (1.47–3.13 and 1.02–2.58 fold increase, respectively). The SDS-PAGE (sodium dodecyl sulfate-polyacrylamide gel electrophoresis) analysis revealed the presence of five protein bands at a molecular weight between 31.7 and 280.9 kDa. These proteins showed the highest homology to hypothetical proteins and porins from E. coli, Delftia sp. and Pseudomonas rhodesiae. Based on obtained results it can be concluded that biogenic AgNPs were capped with proteins and demonstrated potential as antimicrobial and anticancer agent.

Objective: Synthesize silver nanoparticles using a green synthesis approach and encapsulate silver nanoparticles with a naturally occurring polymer, particularly of an-hydroglucose type, like dextran sulfate sodium salt and to study its anticancer activity. Methods: Green synthesis approach is been employed in the synthesis of silver nanoparticles using Psidium guajava leaf extract. The nanoparticles were then encapsulated with dextran sulfate biopolymer and the nanoparticles were subjected to different characterization techniques. The structure of the synthesized nanoparticles was analyzed using X-ray diffraction analysis, the presence of different functional groups was analyzed by FTIR studies. Size and morphology of the prepared nanoparticles were investigated using FESEM analysis. Anticancer activity of the synthesized nanoparticles was tested against the MCF-cell line. Results: The XRD analysis shows the crystalline nature of the synthesized nanoparticles. The stretching and vibrating modes of different functional groups were confirmed by FTIR result. The SEM image confirmed the presence of spherical shaped nanoparticles and the TEM image confirmed the average size of the particles to be around 24 nm. The Ag-DS NPs showed 91% cell inhibition for the concentration of 100 μg/ml, indicating the cytotoxicity of the nanoparticles against MCF-7 cell line. Conclusion: Dextran sulfate stabilized silver nanoparticles show potent anticancer activity against MCF-7 cell line.

AbstractThe application of green synthesis in nanotechnology is growing day by day. It’s a safe and eco-friendly alternative to conventional methods. The current research aimed to study raw royal jelly’s potential in the green synthesis of silver nanoparticles and their antibacterial activity. Royal jelly served as a reducing and oxidizing agent in the green synthesis technology of colloidal silver nanoparticles. The UV–Vis maximum absorption at ~ 430 nm and fluorescence emission peaks at ~ 487 nm confirmed the presence of Ag NPs. Morphology and structural properties of Ag NPs and the effect of ultrasound studies revealed: (i) the formation of polydispersed and spherical particles with different sizes; (ii) size reduction and homogeneity increase by ultrasound treatment. Antibacterial activity of different concentrations of green synthesized Ag NPs has been assessed on Gram-negative S. typhimurium and Gram-positive S. aureus, revealing higher sensitivity on Gram-negative bacteria.
