“…Similarly, the strong relationship between AgNPs absorption spectra at extreme acidic and alkaline pH conditions of 2 and 11 could be attributed to these conditions have nearly similar effects on the AgNPs. This behavior is in line with earlier studies that showed that extreme changes in pH affect the shape and size of the particles because of the pH's ability to alter the charge of biomolecules by having the potential to affect their capping as well as stabilizing abilities leading to a shift in the peak wavelength thereby indicating a slight increase in size of the particles [47,54,55]. Generally, the reported stability plays a critical role in ensuring maintenance of effectiveness of the AgNPs and thus helps overcome one of the obstacles encountered by many conventional crude extracts from plants which lose effectiveness in vivo due to the changing pH gradients as previously reported [38].…”

“…The specific pH conditions tested were pH 2, 4, 7, 9, and 11. The pH were adjusted by either adding drops of 1 N NaOH or 1 N HCl until the desired pH was achieved as observed on the pH meter [54,55]. The absorbance spectra of the suspensions were then measured on the UV/VIS in a scan range of 300 nm to 650 nm.…”

“…About 10 ml of the formed AgNPs suspension in boiling tubes were subjected to different temperature conditions by heating in a digital water bath for about 3 minutes each and measuring the absorbance spectra on the UV/VIS in a scan range of 350 nm to 650 nm [55]. The temperature tested included room temperature (25ºC), 35ºC, 45ºC, 55ºC, 65ºC, 75ºC, and 85ºC.…”

Introduction: The biological green synthesis of nanoparticles via nanobiotechnology processes have a significant potential to boost nanoparticles production without the use of harsh, toxic, and expensive chemicals commonly used in conventional physical and chemical processes. Annona muricata, a tropical plant belonging to family Annonaceae is one of the most used plants in folk medicine because of its many medicinal uses and therefore presents a strong candidate for use in green synthesis. Aims: The aim of this study was to optimize a method for the synthesis of Silver Nanoparticles (AgNPs) from ethanolic extracts of leaves of Annona muricata as well as to characterize the green synthesized AgNPs. Methodology: AgNPs were synthesized from Annona muricata leaves using AgNO3 solution. The AgNPs were characterized using spectroscopy and microscopy techniques. Results: The formed AgNPs had an absorption maximum at 429 nm using UV–Visible spectroscopy and were stable under different pH, temperature, and storage conditions. Fourier transform infrared analysis revealed the different functional groups responsible for the synthesis and stabilization of the AgNPs. Scanning electron microscopy analysis revealed a spherical nature of the synthesized AgNPs. Energy dispersive x-ray spectroscopy analysis showed presence of Ag, O, and Cl with Ag having the highest composition at 60%. X-Ray Diffraction and Dynamic Light Scattering revealed a crystalline nature of AgNPs with an average size of 87.36 nm and a polydispersity index of 0.16 respectively. Transmission Electron Microscopy analysis further confirmed the crystalline and spherical nature of the AgNPs. Conclusion: In this article, an efficient, eco-friendly and low-cost method for the synthesis and recovery of stable AgNPs using Annona muricata leaves ethanolic extracts as both a reducing and capping agent has been reported for the first time. The synthesized AgNPs could be promising candidates for many biomedical, clinical, engineering, and polymer applications.

“…Moreover, the rate of the reaction time is slow, although the fabrication circumstances are insignificant [3]. Albeit for the biosynthesis of MNPs from the salt of the corresponding metal, the most favourable alternative is to utilise plant extract as they are more affordable, simple, basic, quick, and less vitality broad process as combination can be done at room temperature inside couple of minutes and simple to scale up too [18,19]. It has been well established that nano silver is an effective killing agent against a wide range of Gram-negative and Gram-positive microorganisms [20].…”

The plant-based biological molecules possess exceptionally controlled assembling properties to make them suitable in the synthesis of metal nanoparticles. In the present study, an efficient simple one-pot method was employed for the synthesis of silver nanoparticles (SNPs) from the Rangoon creeper (RC) aqueous leaf extract. Biomolecules present in the leaf extract play a significant role as reducing agent as well as capping agent in the formation of RC-SNPs. The formation of RC-SNPs was confirmed by using several analytical techniques such as Fourier-transform infrared spectroscopy and ultraviolet-visible spectrophotometer studies. The presence of a sharp surface plasmon resonance peak at 449 nm showed the formation of RC-SNPs. X-ray diffraction analysis showed the crystalline nature of the RC-SNPs with a face-centred cubic structure. Elemental analysis of RC-SNPs was done by using energy-dispersive X-ray spectroscopy and X-ray photoelectron spectroscopy. The morphology of RC-SNPs was examined by transmission electron microscopy (TEM) in the nano range 12 nm, and thermogravimetric-differential thermal analysis demonstrated the mechanical strength of RC-SNPs at various temperatures. The authors' newly synthesised RC-SNPs exhibited significant anti-bacterial activity against Staphylococcus aureus and Escherichia coli.

“…The pH modification leads to natural phytoreagent's charges changes in the extract composition. The charges changes affect on phytoreagent's ability to bind and to reduce cations and anions of metals during the nanoparticles synthesis and is reflected on NPs shape, size and yield [12,20,21]. Increase of temperature promotes the increase of reaction rate and the efficiency of NPs synthesis [15,16].…”

Green synthesis of metal nanoparticles (NPs) using plant extracts is a nontoxic and ecofriendly method as compared to chemical and physical methods. The production of nanoparticles with plant extract usage has an important advantages. The aim of our research was to establish the conditions for biogenic synthesis of silver nanoparticles using extracts of the medicinal plants and in vitro cultures of medicinal plants. Plant phenolic compounds with strong oxidation-reduction properties can serve as reducing agents of metal ions to NPs. So for the technology of biogenic synthesis of NPs elaboration the most important stage is to choice the plant which will play a role of «biofactory». The medicinal plants and in vitro cultures of medicinal plants have been screened on the biologically active substances (BAS) content, because BAS are the reducing agents for silver nitrate. The phenolic compounds quantitative content screening have revealed that Silybum marianum, Agastache rugosa, Melittis sarmatica and Digitalis purpurea are the best candidates for NPs synthesis. The various factors affecting on the number of synthesized silver nanoparticles have been determined. These factors are: the concentrations of silver nitrate and reducing agents, the time of synthesis, the temperature and pH of reaction medium. The primary conditions for AgNPs synthesis in Agastache rugosa, Silybum marianum, Melittis sarmatica and Digitalis purpurea extracts have been established. The maximum yield of AgNPs in Agastache rugosa and Digitalis purpurea extracts were observed at 24 C, for Melittis sarmatica -at 35 C and for Silybum marianum extract -at 18 C. The optimal conditions for AgNPs synthesis -pH 9,0 and AgNO 3 concentration in solution -1  10 -2 M.
