“…After the addition of AgNO 3 aqueous solution with bio extract, the FTIR spectrum revealed a significant change in absorption peaks at 1021, 1443, 1634, and 3428 cm −1 , which confirms that the functional groups interacted with the surface of the AgNPs. The biomolecule compounds, such as polyphenol, and their derivatives, including tannic acid, flavonoids, phytosterols, and phenolic compounds, served as reducing agents of silver ion to silver nanoparticles because of their oxidation-reduction potential [60]. A recent study suggests that plant metabolites, such as flavonoids, phenols, and aromatic compounds soluble in the aqueous extract, exhibit remarkable performance in the bioreduction of Ag ions and the stabilization of silver nanoparticles [61].…”

The current work concentrated on the green synthesis of silver nanoparticles (AgNPs) through the use of aqueous Citruslimon zest extract, optimizing the different experimental factors required for the formation and stability of AgNPs. The preparation of nanoparticles was confirmed by the observation of the color change of the mixture of silver nitrate, after the addition of the plant extract, from yellow to a reddish-brown colloidal suspension and was established by detecting the surface plasmon resonance band at 535.5 nm, utilizing UV-Visible analysis. The optimum conditions were found to be 1 mM of silver nitrate concentration, a 1:9 ratio extract of the mixture, and a 4 h incubation period. Fourier transform infrared spectroscopy spectrum indicated that the phytochemicals compounds present in Citrus limon zest extract had a fundamental effect on the production of AgNPs as a bio-reducing agent. The morphology, size, and elemental composition of AgNPs were investigated by zeta potential (ZP), dynamic light scattering (DLS), SEM, EDX, X-ray diffraction (XRD), and transmission electron microscopy (TEM) analysis, which showed crystalline spherical silver nanoparticles. In addition, the antimicrobial and antioxidant properties of this bioactive silver nanoparticle were also investigated. The AgNPs showed excellent antibacterial activity against one Gram-negative pathogens bacteria, Escherichia coli, and one Gram-positive bacteria, Staphylococcus aureus, as well as antifungal activity against Candida albicans. The obtained results indicate that the antioxidant activity of this nanoparticle is significant. This bioactive silver nanoparticle can be used in biomedical and pharmacological fields.

“…Usually, the bottom-up processes using gas (Kerminen et al, 2018;Khitab et al, 2018) and liquid (Jadoun et al, 2021;Khitab et al, 2018;Mastalska-Popławska et al, 2020;Shaikh et al, 2021;Wichaita et al, 2019) phases are employed. However, liquid-phase methods have some weak points: e.g., additional post-treatments, such as solid-liquid separation, liquid waste treatment, drying and disintegration of aggregates, which leads to the increase in the energy consumption and process cost.…”

The United Nations Sustainable Development Goals (SDGs) have attracted much attention due to increasing interest in global social, energy and environmental problems. The immediate contribution to the achievement of the SDGs is required in all individual and industrial activities. The industries dealing with fine particles are also no exception to the demand and have actively worked on the contribution. Conventionally, fine particles have been industrially synthesized in gas, liquid and solid phases using top-down and bottom-up approaches. Among them, dry synthesis processes are promising from a viewpoint of the SDGs due to the solvent-free and simplicity, which can lead to energy saving, efficient resource utilization, waste management, etc. This review describes dry mechanical processes for synthesis of fine particles, particularly focusing on grinding and mechanochemical treatment.

“…Plant extract-mediated synthesis of MNPs, including AgNPs, have been widely explored and used for various applications [77]. Parameters such as metal precursor concentration, pH, phytochemical composition, reaction temperature and time largely influence the physicochemical properties of AgNPs, such as size, shape, surface charge and morphology [110,111], but can also influence the bioactivities of the AgNPs. Most studies have reported the synthesis of AgNPs in a basic pH medium which seems to produce NPs with a higher stability [112] and a more monodisperse nature.…”

Plant Extract-Synthesized Silver Nanoparticles for Application in Dental Therapy

et al. 2022

Oral diseases are the most common non-communicable diseases in the world, with dental caries and periodontitis causing major health and social problems. These diseases can progress to systematic diseases and cause disfigurement when left untreated. However, treatment of oral diseases is among the most expensive treatments and often focus on restoration of form and function. Caries prevention has traditionally relied on oral hygiene and diet control, among other preventive measures. In this paper, these measures are not disqualified but are brought into a new context through the use of nanotechnology-based materials to improve these conventional therapeutic and preventive measures. Among inorganic nanomaterials, silver nanoparticles (AgNPs) have shown promising outcomes in dental therapy, due to their unique physicochemical properties and enhanced anti-bacterial activities. As such, AgNPs may provide newer strategies for treatment and prevention of dental infections. However, numerous concerns around the chemical synthesis of nanomaterials, which are not limited to cost and use of toxic reducing agents, have been raised. This has inspired the green synthesis route, which uses natural products as reducing agents. The biogenic AgNPs were reported to be biocompatible and environmentally friendly when compared to the chemically-synthesized AgNPs. As such, plant-synthesized AgNPs can be used as antimicrobial, antifouling, and remineralizing agents for management and treatment of dental infections and diseases.
