“…X-ray diffraction was used to evaluate the crystalline structures in the gel sample [ 29 , 30 ]. The measurements were performed with an Ultima IV diffractometer (Rigaku Corp., Tokyo, Japan) equipped with parallel beam optics, using CuKα radiation (λ = 1.5418 Å), at 40 kV and 30 mA, over the 5–80° range, at a scanning rate of 1°·min −1 , with a step width of 0.02°, in continuous mode, at room temperature and atmospheric pressure.…”

“Green chemistry” is a simple and easily reproductible method that provides nanoparticles characterized by better stability and good dispersion in an aqueous solution. Nanoparticles can be synthesized by algae, bacteria, fungi, and plant extracts. Ganoderma lucidum is a commonly used medicinal mushroom with distinctive biological properties, such as antibacterial, antifungal, antioxidant, anti-inflammatory, anticancer, etc. In this study, aqueous mycelial extracts of Ganoderma lucidum were used to reduce AgNO3 to form silver nanoparticles (AgNPs). The biosynthesized nanoparticles were characterized by UV-visible spectroscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR) analysis. The maximum UV absorption was obtained at 420 nm, which represents the specific surface plasmon resonance band for biosynthesized silver nanoparticles. SEM images showed particles as predominantly spherical, while FTIR spectroscopic studies illustrated the presence of functional groups that can support the reducing of ion Ag+ to Ag(0). XRD peaks ratified the presence of AgNPs. The antimicrobial effectiveness of synthesized nanoparticles was tested against Gram-positive and Gram-negative bacterial and yeasts strains. The silver nanoparticles were effective against pathogens, inhibiting their proliferation, and thus reducing the risk to the environment and to public health.

“…The 1:10 ratio was optimal and allowed the authors to obtain nanoparticles with an average size of 45 nm with antimicrobial and antioxidant activity. In another study, the utilization of a Ganoderma lucidum fruit body extract was scrutinized under different operational conditions including the AgNO 3 :extract ratio, reaction time and temperature to establish an effective myconanosynthesis method with a high yield rate and nanoparticle stabilization [ 125 ]. Vetchinkina et al studied the effect of the Lentinus edodes culture age and stage of ontogenesis on the biogenic AgNP synthesis using culture liquids of different ages [ 41 ] and extracts obtained from the different morphological structures of L. edodes [ 128 ].…”

Fungi are very promising biological objects for the green synthesis of nanoparticles. Biogenic synthesis of nanoparticles using different mycological cultures and substances obtained from them is a promising, easy and environmentally friendly method. By varying the synthesis conditions, the same culture can be used to produce nanoparticles with different sizes, shapes, stability in colloids and, therefore, different biological activity. Fungi are capable of producing a wide range of biologically active compounds and have a powerful enzymatic system that allows them to form nanoparticles of various chemical elements. This review attempts to summarize and provide a comparative analysis of the currently accumulated data, including, among others, our research group’s works, on the variety of the characteristics of the nanoparticles produced by various fungal species, their mycelium, fruiting bodies, extracts and purified fungal metabolites.

“…Figure 1 demonstrates the structure of Ag/GO nanocomposite reported that the interaction between the plasmonic nanoparticles and oxygen functional groups is dominated by electrostatic interaction between the GO surface and the nanoparticles. [2,3,19] The ex-situ hybridization of Ag/GO is illustrated in figure 3. The ex-situ synthesis method is more suitable for large-scale industrial applications.…”

“…The antibacterial process of Ag/GO can be divided into 4 stages as illustrated in Figure 6 [19] : Stage I: The dispersion of Ag/GO suspension into water forms a stable colloidal system that can increase the interaction area with the bacteria. GO possesses a large surface area and includes many functional groups such as (−O−), (−OH), (−COOH), and (−C=O), which can interact with cell membrane via hydrogen bondings, and electrostatic interaction to capture the bacteria.…”

In recent years, the applications of nanomaterials are getting more common in commercial products. Amongst them, silver nanoparticles (AgNPs) are the most well‐known nanomaterials for their outstanding antibacterial properties and potential applications in the biomedical field. The agglomeration of AgNPs due to their high surface energy has diminished the actual antibacterial applications of these plasmonic nanoparticles. To tackle this problem, the AgNPs are grafted onto graphene oxide (GO) sheets (Ag/GO) to minimize the agglomeration of AgNPs and enhance the extraordinary antibacterial characteristics of AgNPs thanks to several outstanding features of GO. Ag/GO composite also exhibits other properties such as good optical sensitivity to trace heavy metal ions, adsorption affinity, and catalytic activity for the removal of organic compounds. With all the possibilities, Ag/GO can be considered a multifunctional nanocomposite that can be applied in various fields such as biomedical treatment and environmental remedy.
