“…While the non‐toxic effect has been observed for metal NPs that are synthesised from garlic [97] or tea [98] extract. However, cytotoxicity and genotoxicity were reported for synthesised silver NPs from pandanus odorifer [99], piper longum extracts [100, 101]. Some claimed that green synthesised metal NPs are more biocompatible in comparison to chemically prepared metal NPs [102].…”

For being applied in medicine as therapeutic agents, nanostructures need to be biocompatible and eco-friendly. Plantderived phenolic acids have been utilised for green synthesis of metallic or metallic oxide nanoparticles (NPs). The phenolic acids play role as both reducing agents and stabilisers in the process of NPs synthesis. Many experiments have been dedicated to develop efficient green synthesis techniques for producing metal NPs. Using phenolic acids represents a reproducible, simple, profitable, and cost-effective strategy to synthesise metal NPs. As a phytochemical for metal NPs synthesis, phenolic acids are antioxidants that represent many health benefits. However, limited studies have been dedicated to the synthesis and characterisation of NPs produced by phenolic acids. Thus, this review focused on phenolic acids mediated nanomaterial synthesis and its biomedical applications. It should be noted the mechanism of metal ion bioreduction, phenolic acids surface adsorption, characterisation, and toxicity of metal NPs made with different phenolic acids have been discussed in this review.

“…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.

“…In particular, silver NPs showed stronger cytotoxicity against chicken macrophages than gold NPs at the same concentration [ 5 , 64 ]. Furthermore, D-AgNPs ( Dendropanax morbifera ) significantly inhibited cancer cell growth (>70%) after 48 h of exposure to higher concentrations of 100 µg·mL −1 [ 65 ]. The cytotoxicity of plant-derived NPs may involve the synergic effects of plant compounds.…”

Biological synthesis of metal nanoparticles has a significant impact in developing sustainable technologies for human, animal, and environmental safety. In this study, we synthesized gold and silver nanoparticles (NPs) using Sedeveria pink ruby (SP) extract and characterized them using UV–visible spectrophotometry, FESEM-EDX, HR-TEM, XRD, and FT-IR spectroscopy. Furthermore, antimicrobial and antioxidant activities and cytotoxicity of the synthesized NPs were evaluated. UV–visible absorption spectra showed λmax at 531 and 410 nm, corresponding to the presence of SP gold NPs (SP-AuNPs) and SP silver NPs (SP-AgNPs). Most NPs were spherical and a few were triangular rods, measuring 5–30 and 10–40 nm, respectively. EDX elemental composition analysis revealed that SP-AuNPs and SP-AgNPs accounted for >60% and 30% of NPs, respectively. Additionally, some organic moieties were present, likely derived from various metabolites in the natural plant extract, which acted as stabilizing and reducing agents. Next, the antimicrobial activity of the NPs against pathogenic microbes was tested. SP-AgNPs showed potent antibacterial activity against Escherichia coli and Yersinia pseudotuberculosis. Moreover, at moderate and low concentrations, both NPs exhibited weak cytotoxicity in chicken fibroblasts (DF-1) and macrophages (HD11) as well as human intestinal cancer cells (HT-29). Meanwhile, at high concentrations, the NPs exhibited strong cytotoxicity in both chicken and human cell lines. Therefore, the synthesized SP-AuNPs and SP-AgNPs may act as promising materials to treat poultry diseases.
