“…3(f) exhibited that the zeta potential value of the synthesized AgNPs was 0.28 mV, which is more neutral than our previous AgNPs that were prepared by extract of Cilembu sweet potatoes (−41.0 mV) [3]. Since the zeta potential value of the synthesized AgNPs was in the range of 0 ± 3 mV, the synthesized AgNPs are susceptible to agglomeration and might form big particles after some time [26]. Therefore, it is reasonable that the DLS result of the obtained AgNPs (145.5 nm, with PI 0.469) is relatively bigger and less uniform than the DLS result of our previous work (105.5 ± 12.6 nm, with PI 0.29 [3]).…”

Silver nanoparticles (AgNPs) are fascinating materials for biomedical applications thanks to their strong antibacterial activity and biocompatibility. This study applied the green synthesis method using 0.5 wt.% Seminyak leaf extract and assisted with one min microwave irradiation to enhance AgNPs formation. Extremely small sizes AgNPs with an average particle size of 9.1 ± 4.1 nm and spherical shapes were obtained. The synthesized AgNPs displayed potent antibacterial activity against Escherichia coli and Staphylococcus aureus bacteria with a zone of inhibition of 12.3 ± 0.1 and 13.7 ± 0.7 mm, respectively. The MTT assay results demonstrated that the cells’ viability of the obtained AgNPs was 88.5 ± 7.0 %, implying biocompatibility for biomedical applications.

The present study reports a hydrogel-based sunlight-assisted synthesis of gold nanoparticles (Au NPs) with enhanced antimicrobial and wound healing potential. The hydrogel extracted from the seeds of Cydonia oblonga was used as a reducing and capping agent to synthesize Au NPs for the first time. The as-synthesized Au NPs were characterized for an average size, shape, surface functionalization, antimicrobial, and wound healing capabilities. The cubic and rectangular-shaped Au NPs with an average edge length of 74 ± 4.57 nm depicted a characteristic surface plasmon resonance band at 560 nm. The hydrogel-based Au NPs inhibited the growth of microorganisms in zones with 12 mm diameter. In-vitro experiments showed that a minimum inhibitory concentration of Au NPs (16 µg/mL) was sufficient to mimic the 95% growth of pathogenic microorganisms in 24 h. In vivo treatment of wounds with Au NPs in murine models revealed a 99% wound closure within 5 days. Quantitative PCR analysis performed to decipher the role of Au NPs in enhanced wound healing showed an increase in the expression levels of NANOG and CD-34 proteins.

“…It is quite obvious that phytopathogens along with foodborne bacteria significantly contribute to the overall loss in crop yields worldwide (Mansfield et al, 2012 ; Hameed et al, 2018 ). Sustainable food production through biological methods is an inexpensive substitute for conventional physical and non-biodegradable chemical methods (Allafchian et al, 2022 ; Soltani Nejad et al, 2023 ), which aims to hinder the development of a multiple resistance crisis among pathogenic microorganisms in relation to these substances (Karimi et al, 2019 ), preventing their extended environmental pollution and reduced effectiveness (Giaouris et al, 2014 ).…”

“…In general, plant-derived essential oils (EOs) have gained momentum for research purposes as non-phytotoxic compounds are potentially effective against plant pathogenic bacteria (Bajpai et al, 2011 ). Being comparatively harmless, these compounds have motivated the focus of innovative researchers for treating distinct challenging diseases (Hajian-Maleki et al, 2019 ; Allafchian et al, 2022 ), and several researchers have extensively documented the antimicrobial properties of EOs and their constituents (Nazzaro et al, 2013 ; Chouhan et al, 2017 ; Raveau et al, 2020 ).…”

Studies on the antibacterial activity of the essential oil of E. billardieri are limited. In this study, we identified this herb as a natural complex effective against several bacteria by employing disk diffusion and broth microdilution susceptibility methods. Primary estimation of the antimicrobial effect of this herbal compound by disk diffusion method showed that the oil could inhibit the growth of the tested bacteria by the appearance of haloes between 8.25 and 21.25 mm. In the next step, the oil was found to be active against all 24 tested Gram-negative and Gram-positive bacteria in the broth media, at minimum inhibitory concentrations ranging from 0.67 to 34.17 g L−1. Furthermore, Enterococcus faecalis and Curtobacterium flaccumfaciens pv. flaccumfaciens were the most sensitive food and plant pathogenic bacteria, respectively. Gas chromatography–mass spectrometry analysis was conducted to assign the ingredients present in the oil; 34 different components representing 95.71% of the total oil were identified, with n-hexadecanoic acid being the dominant component, followed by 2-Pentadecanone, 6,10,14-trimethyl, 1H-Indene, 1-ethylideneoctahydro-, and Cinnamyl tiglate. These findings demonstrate, for the first time, a broad spectrum of the antibacterial capacity of E. billardieri. Based on these observations, the oil could be applied as a natural preservative with the potential for designing novel products. Its bioactive agents can also be isolated for further use in the food and agricultural industries.
