Silver nanoparticles (Ag NPs) with antibacterial activity can be prepared in different ways. In our case, we used ecological green synthesis with Agrimonia eupatoria L. The plant extract was used with Ag NPs for the first time to prepare termosensitive in situ gels (ISGs). Such gels are used to heal human or animal skin and mucous membranes, as they can change from a liquid to solid state after application. Ag NPs were characterized with various techniques (FTIR, TEM, size distribution, zeta potential) and their antibacterial activity was tested against Staphylococcus aureus and Escherichia coli. In accordance with the TEM data, we prepared monodispersed spherical Ag NPs with an average size of about 20 nm. Organic active compounds from Agrimonia eupatoria L. were found on their surfaces using FTIR spectroscopy. Surprisingly, only the in situ gel with Ag NPs showed antibacterial activity against Escherichia coli, while Ag NPs alone did not. Ag NPs prepared via green synthesis using plants with medicinal properties and incorporated into ISGs have great potential for wound healing due to the antibacterial activity of Ag NPs and the dermatological activity of organic substances from plants.

“…Moreover, some sharp high intensity peaks in the XRD patterns show that they are mainly composed of AgCl. The main peaks in 2ϴ equaled 27.9, 32.3, 54.9, 57.5, 67.2, 74.6, and 76.8 which were attributed to cubic crystallography plates (111), (200), (220), (311), (222), (400), and (331) respectively (JCPDS number 31-1238) [ 62 ].…”

Recently there have been a variety of methods to synthesize silver nanoparticles, among which the biosynthesis method is more noticeable due to features like being eco-friendly, simple, and cost-efficient. The present study aims for the green synthesis of silver nanoparticles from the extract of the three plants A. wilhelmsi, M. chamomilla, and C. longa; moreover, it pledges to measure the antibacterial activity against some variants causing a skin rash. The morphology and size of the synthesized silver nanoparticles were evaluated by UV.vis, XRD, SEM, and FTIR analyses. Then results showed a color alteration from light yellow to dark brown and the formation of silver nanoparticles. The absorption peak with the wavelength of approximately 450 nm resulting from the Spectrophotometry analysis confirmed the synthesis of silver nanoparticles. The presence of strong and wide peaks in FTIR indicated the presence of OH groups. The SEM results showed that most synthesized nanoparticles had a spherical angular structure and their size was about 10 to 20 nm. The highest inhibition power was demonstrated by silver nanoparticles synthesized from the extract combined from all three species against Gram-positive bacteria Staphylococcus aureus and Staphylococcus epidermidis (23 mm) which had a performance far more powerful than the extract. Thus, it can be understood that the nanoparticles synthesized from these three species can act as potential environment-friendly alternatives to inhibit some variations causing skin disorders; an issue that calls for further clinical studies.

“…When synthesizing Ag NPs in an environmentally friendly manner, the plant extract eliminates chemicals from the AgNO 3 solution. [20][21][22] The nuclea-tion phase of this process involves Ag atoms utilizing a high activation energy to form tiny nuclei, whereas the growth phase entails the grouping of these small nuclei to form NPs. Because Ag has a high reduction potential, stable particles can be formed in aqueous solutions that do not contain stabilizers after Ag NPs are synthesized.…”

Biological processes were used to create Ag@AgCl nanoparticles in an eco‐friendly manner. Grape seed extracts were used to create Ag@AgCl nanoparticles for this study. The antifungal activity of nanoparticles was tested using fruit‐rotting fungi. UV‐Vis spectrophotometry was used to analyze the nanoparticles to determine the extent of surface plasmon resonance (SPR) band formation. The phytochemicals employed in nanoparticle synthesis were studied using Fourier transform infrared spectroscopy (FT‐IR). X‐ray diffraction (XRD) studies revealed that the Ag@AgCl nanoparticles were crystalline. Field‐emission scanning electron microscopy (FE‐SEM) was used to determine the morphological structure of the nanoparticles. FE‐SEM images determined the average particle size of Ag@AgCl. Energy‐dispersive X‐ray spectroscopy (EDAX was used to examine the elemental composition. Transmission electron microscopy (TEM) and atomic force microscopy (AFM) were employed. Fungi that cause fruit deterioration have been isolated from bananas and papaya fruits. The Ag@AgCl nanoparticles were evaluated for fungal activity against Rhizopus stolonifer, Alternaria species, Aspergillus niger, Aspergillus fumigatus, and Fusarium oxosporum. An agar‐well diffusion study indicated that these nanoparticles had good antifungal sensitivity against fungal infections. However, this study was adequate to allow the inhibitory activity to proceed to the optimization phase, where we dealt with RSM‐based desirability function prediction. The results also demonstrate that the model performs well, implying that it can provide an accurate estimate of output. usingthe impact,the desirability of each factorzoneson
