“…The spherical AgNPs with a mean diameter of 11 nm presented a MIC of 15.6 μg mL −1 and an MBC of 31.25 μg mL −1 . Our results are interesting when compared with a recent study conducted by Shaaban et al 35 using AgNPs from Moringa oleifera leaf extract (average size ranged from 24 to 40 nm). The authors reported MIC and MBC values ranging from 1.25 mg mL −1 against S. aureus and P. aeruginosa , which are higher than those in our study and Al-Momani et al 's.…”

“…Assays were performed in triplicate. After the first screening, since no survival was detected for concentrations over 50 μg mL −1 , a new assay was repeated for the AgNP concentrations of 5,10,15,20,25,30,35,40,45, and 50 μg mL −1 .…”

“…This was surprising, as many articles have described the opposite finding. Nanoparticles prepared via green synthesis using Moringa oleifera leaf at a concentration of 1 mM and incorporated into bacterial cellulose and filter paper discs exhibited antimicrobial activity against Staphylococcus aureus ATCC 6538 and Pseudomonas aeruginosa ATCC 9027 [ 65 ]. Silver nanoparticles synthesized with probiotic bacteria showed increased antibacterial activity and increased antioxidant activity [ 66 ].…”

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.

“…Fourier transform infrared spectroscopy showed that BC and filter paper could both hold the nanoparticles while scanning electron microscopy showed major distortion effects on bacterial cell morphology. The results suggest BC impregnated with green synthesized silver nanoparticles is highly effective in wound healing treatments [ 11 ]. The new research developed a nanocomposite of multi-walled carbon nanotubes (MWCNTs) decorated with silver nanoparticles (Ag NPs).…”

Background The main activity of the skin is to create a protective barrier against damage. Loss of the skin due to injury or disease and failure to regenerate the affected area may result in disability, infection, or even death. We conducted a clinical trial to evaluate the therapeutic effect of dressing containing silver in process of healing skin blisters caused by limb fractures. Method This is a pioneering randomized trial that compares the effectiveness of two dressings containing silver (Ag coat) and Gaz Vaseline among patients with skin blisters due to bone fractures who were randomly selected from patients referred to the Kashani Medical Training Center. There were two treatment groups containing 16 patients treated with Ag coat and 15 patients treated with Gaz Vaseline. Pictures were taken of blisters on days 0, 7, and 14 to evaluate the healing process. The amount of pain, duration of the visit (measured by minutes), and general condition of the wound were checked. The amount of pain, duration of visit (measured by minutes) and general condition of the wound was checked. All continuous and categorical data are presented as mean ± standard deviation (SD) and frequency (percentage), respectively. Paired sample T-test and repeated measure analysis of variance (ANOVA), Chi-squared test was used. All pictures were analyzed by Mosaic soft ward. Result During this study, there was no significant difference between the mean of age and BMI and frequency of gender in the two study groups (P > 0.05). There was a significant difference in mean between the duration of the visit, number of dressings, and net cost of dressing $$(p <0.05)$$ ( p < 0.05 ) . In the macroscopic study and analysis for evaluation and comparing wound area with the Mosaic soft ward, there was significant relation in time (p1 = 0.00). There is no significant difference between the groups (p2 = 0.84). There was a significant difference between time and group (p3 = 0.00). On day 14 the wound area between groups had a significant difference (p4 = 0.00) (Table 3). In the VAS score there was a significant difference in time, and group (p1,2 = 0.00), there was no significant relation between time and group (p3 = 0.62). On all days the wound area between groups had a significant difference (p4 = 0.00). Conclusion In conclusion, Ag coat dressing, not only has a significant effect on wound healing but also, decreases pain, shorter visit time, and its more cost-effective.
