“…[4][5][6][7][8]9 Therefore, the green synthesis of nanoparticles is a hot research area nowadays, allowing the biosynthesis of safe, effective, low cost, and eco-friendly drugs, often mediated by the utilization of natural plant products. 4,10 Pimpinella anisum L. (Apiaceae), commonly known as anise, is a well-known culinary herb, utilized for preparation of famous liqueurs but also largely used for its medicinal properties. 11,12 For the latter application, the seeds are mainly used.…”

Background The present study focused on a simple and eco-friendly method for the synthesis of silver nanoparticles (AgNPs) with multipurpose anticancer and antimicrobial activities. Materials and methods We studied a green synthesis route to produce AgNPs by using an aqueous extract of Pimpinella anisum seeds (3 mM). Their antimicrobial activity and cytotoxicity on human neonatal skin stromal cells (hSSCs) and colon cancer cells (HT115) were assessed. Results A biophysical characterization of the synthesized AgNPs was realized: the morphology of AgNPs was determined by transmission electron microscopy, energy dispersive spectroscopy, X-ray powder diffraction, and ultraviolet-vis absorption spectroscopy. Transmission electron microscopy showed spherical shapes of AgNPs of P. anisum seed extracts with a 3.2 nm minimum diameter and average diameter ranging from 3.2 to 16 nm. X-ray powder diffraction highlighted the crystalline nature of the nanoparticles, ultraviolet-vis absorption spectroscopy was used to monitor their synthesis, and Fourier transform infrared spectroscopy showed the main reducing groups from the seed extract. Energy dispersive spectroscopy was used to confirm the presence of elemental silver. We evaluated the antimicrobial potential of green-synthesized AgNPs against five infectious bacteria: Staphylococcus pyogenes (29213), Acinetobacter baumannii (4436), Klebsiella pneumoniae (G455), Salmonella typhi , and Pseudomonas aeruginosa. In addition, we focused on the toxicological effects of AgNPs against hSSC cells and HT115 cells by using in vitro proliferation tests and cell viability assays. Among the different tested concentrations of nanoparticles, doses < 10 µg showed few adverse effects on cell proliferation without variations in viability, whereas doses >10 µg led to increased cytotoxicity. Conclusion Overall, our results highlighted the capacity of P. anisum -synthesized AgNPs as novel and cheap bioreducing agents for eco-friendly nanosynthetical routes. The data confirm the multipurpose potential of plant-borne reducing and stabilizing agents in nanotechnology.

“…Use of plant and herbal extracts therefore provides an ecofriendly route for controlled and precise synthesis of metal nanostructures of various sizes and shapes. 17,18 To date, several methods have been reported for phytosynthesis of silver nanostructures including nanoparticles, 18 nanoflowers, 19 nanorods, 20 and nanoflakes. 21 Presence of microorganisms in textile fabrics, medical implants and tools, food containers, and water transport and treatment systems can cause infectious diseases and must be controlled; For example, Bacillus subtilis and Pseudomonas aeruginosa cause brain inflammatory diseases, allergic sensitivity, 22,23 and lung infections or pneumonia in patients with compromised immune systems and hospital infections, respectively.…”

Silver nanoparticles have been synthesized using only Myrtus communis L. leaf extract by a facile procedure without other reagents. The extract played the roles of both reducing and capping agent. The nanoparticles were characterized using field-emission scanning microscopy, and remained stable for at least 3 weeks. Antibacterial activity of the nanoparticles was evaluated toward Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, Staphylococcus aureus, methicillin-resistant Staphylococcus aureus, and Enterococcus faecalis based on inhibition zone disk diffusion assays. The minimum inhibitory and bactericidal concentrations of the nanoparticles were obtained. Mechanisms for the antibacterial activity were proposed.

Neutron activation analysis of the Pleurotus ostreatus showed that adding of solid solution of ZrO2-Y2O3 hydroxide and oxide (3 mol % Y2O3) nanoparticles of size 4 and 9 nm at a concentration of 0.2 weight percent in a nutrient medium (Czapek) alters the character of physiological processes in the biological tissues of the mushrooms. This is manifested in the form of a significant change in morphological and physiological characteristics of the mushrooms and the elemental composition of the dry biomass. In particular, it is shown that the intercalation of nanoparticles into the tissues of the mushrooms leads to an increase of 1.3-1.4 times (more than 2.6 g/dm 3 ) of biomass accumulation (industrial strain HK 35) and decrease of 1.7-1.8 times (below 1.7-2.5 mg/mm 3 ) of concentrations of extracellular proteins into the culture fluid at a substantially constant value of the acidity. It is shown that the addition of ZrO2+3 mol % Y2O3 nanoparticles of sizes 4 or 9 nm into tissue of mushroom at step of the mother mycelium in very small concentrations can alter effectively the chemical composition of the substances produced by the cells and consequently, its physiological activity. It is shown that the use of low concentrations of ZrO2 nanoparticles allow to increase the yield and resistance of crops to diseases up to 1.2-1.5 times, as well as in the long term can be used in biomedical technologies for the treatment of cancer diseases.
