“…Silver nanoparticles synthesis using plant extracts has been considered expansively as choice for a green method as defined by Banach and Pulit-Prociak (2017) to achieve nanoparticles through easy and efficient metal ions reduction by plant extracts active molecules. In this connection, Pelargonium hortorum leaf (Rivera-Rangel et al 2018), green tea (Sökmen et al 2017), Rosa canina (Pulit and Banach 2014) 1 3…”

The fungal-mediated silver nanoparticles (AgNPs) biosynthesis optimization via the application of central composite design (CCD) response surface to develop an effective ecofriendly and inexpensive green process was the aim of the current study. Nanosilver biosynthesis using the NRC1731 cell-free filtrate (CFF) was studied through involving the most parameters affecting the AgNPs green synthesis and its interactions effects. The statistical optimization models showed that using 59.37% of CFF in reaction containing 1.82 mM silver nitrate for 34 h at pH 7.0 is the optimum value to optimize the AgNPs biosynthesis. The obtained AgNPs were characterized by means of electron microscopy, UV/visible spectrophotometry, energy dispersive X-ray analysis and infrared spectroscopy to elucidate its almost spherical shape with diameter of 3-20 nm. The produced AgNPs exhibited a considerable antimicrobial activity against, in addition to.

“…Moreover as reported by, 25 there is a possibility of quinone formation. 27,29 On the other hand, there is a second mechanism based on the reducing and stabilizing effect of hydroxyl groups of BC. Based on the reported literature, the hydroxyl groups of BC act as the sites for the adsorption, nucleation, and growth of silver nanoparticles.…”

In this study, an innovative in situ green strategy was applied to prepare bacterial cellulose/silver nanocomposites using green tea as a substrate for the fermentation of Acetobacter xylinum bacteria and a reducing agent for the in situ synthesis of silver nanoparticles. The samples were analyzed by different characterization tests including field emission scanning electron microscopy (FESEM), X-ray diffraction analysis (XRD), UV-vis spectroscopy, atomic absorption spectroscopy, and ATR. The results indicated the excellent antibacterial activities with 100% bacterial reduction percentage and inhibition zones of 2.6 and 2.8 cm against S. aureus and E. coli, respectively. Moreover, water absorption percentage and vertical wicking measurements supported the hydrogel properties of the prepared bio-cellulose/silver nanocomposites. Finding of this research suggested the potential of the proposed green route for preparing antibacterial BC which can be regarded as a candidate for future wound healing applications.

“…Consequently, the more the time of exposure, the more the bandwidth and increase in absorption maxima resulting in polydispersity and size increment of the CPAgNPs (27,28). In addition, the bioreduction process leading to the formation of CPAgNPs occurred due to the availability and interaction of the phytochemical constituents in C. paradisi peel extracts creating the capping and stability effects on the synthesized nanoparticles from aggregation (12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29).…”

“…Contrary to the conventional heating method at ambient temperature, exposing the reaction mixture to microwave irradiation accelerates the reaction medium providing lower energy usage, uniform nucleation and growth conditions for nanoparticles (30,31). In addition, the rapid heating created by the irradiation facilitates ease of releasing the phytochemical constituents in the peel through the disruption of the cell wall into the reaction mixture (29).…”

This study focuses on time-dependent microwave-assisted biosynthesis of silver nanoparticles using aqueous peel extracts of Citrus paradisi as a reducing, stabilizing and capping agent with emphasis on its antibacterial property. Optical, structural and morphological properties of the synthesized Citrus paradisi peel extract silver nanoparticle (CPAgNp) were characterized using UV-visible spectrophotometer, transmission electron microscope (TEM), scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), Brunauer-Emmett-Teller (BET) and Xray diffractometer (XRD). The antimicrobial activity was evaluated using the well-and discdiffusion methods. Characteristic surface plasmon resonance (SPR) wavelength in the range of 420-440 nm at an optimized intensity growth rate typical of silver nanoparticles was obtained. The synthesized CPAgNp are spherical in shape having the size range of 14.84 ± 5 nm and possessing fcc unit phase structure. The Citrus paradisi peel extract mediated AgNp were found to possess a broad-spectrum antimicrobial activity against water-borne pathogenic microbes.
