“…79 The possibility of silica nanoparticle formation with fungal cultures has been barely studied. In addition to our research, 51,52 there have been a number of reports describing the synthesis of silica spheres and quasispheres by the ascomycete Fusarium oxysporum. 80−83 Calcination of such quasispherical, highly crystalline silica nanoparticles by bioleaching of rice husk resulted in the loss of occluded protein and in the formation of porous, often cubic, structures.…”

This article analyzes data on the diversity of shapes and sizes of nanoparticles obtained by green synthesis from HAuCl 4 , AgNO 3 , Na 2 SeO 3 , and Na 2 SiO 3 by using xylotrophic and humus basidiomycetes and soil bacteria. The formation of nanoparticles of various shapes and sizes was controlled by changing the bioreduction conditions, including culture type and age, growth medium, culture liquid, mycelial extract, isolated proteins, and incubation time. Biogenic selenium nanoparticles were represented exclusively by spheres whose size varied from 20 to 550 nm, depending on the culture. Autoclaving of selenium nanoparticles fabricated with bacterial cultures yielded nanowires with a width of 20−150 nm and a length of more than 10 μm. With bacterial culture liquids, silicon nanospheres were synthesized, ranging in size from very small (5−15 nm) to relatively large (250 nm) particles. The use of the Agaricus culture liquid made it possible to obtain mesoporous particles with a size of 30−60 nm. The size and shape of the fabricated gold and silver nanoparticles were very diverse, depending on the bioreduction conditions, and were represented by regular and irregular spheres; large balls; hexagonal, tetragonal, and triangular prisms; tetrahedrons; and nanobelts. The particle size ranged from 1−10 to 200−500 nm.

Silver nanoparticles (AgNPs) represent an excellent option to solve microbial resistance problems to traditionally used antibiotics. In this work, we report optimized protocols for the production of AgNPs using extracts and supernatants of Trichoderma harzianum and Ganoderma sessile. AgNPs were characterized using UV-Vis spectroscopy and transmission electron microscopy, and the hydrodynamic diameter and Z potential were also determined. The obtained AgNPs were slightly larger using the fungal extract, and in all cases, a quasi-spherical shape was obtained. The mean sizes of AgNPs were 9.6 and 19.1 nm for T. harzianum and 5.4 and 8.9 nm for G. sessile using supernatant and extract, respectively. The AgNPs were evaluated to determine their in vitro antibacterial effect against Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus. The minimum inhibitory concentration (MIC) was determined, and in all cases the AgNPs showed an antimicrobial effect, with a MIC varying from 1.26–5.0 µg/mL, depending on the bacterial strain and type of nanoparticle used. Cytotoxicity analyses of AgNPs were carried out using macrophages and fibroblast cell lines. It was determined that the cell viability of fibroblasts exposed for 24 h to different concentrations of AgNPs was more than 50%, even at concentrations of up to 20 µg/mL of silver. However, macrophages were more susceptible to exposure at higher concentrations of AgNPs as their viability decreased at concentrations of 10 µg/mL. The results presented here demonstrate that small AgNPs are obtained using either supernatants or extracts of both fungal strains. A remarkable result is that very low concentrations of AgNPs were necessary for bacterial inhibition. Furthermore, AgNPs were stable for more than a year, preserving their antibacterial properties. Therefore, the reported optimized protocol using fungal supernatants or extracts may be used as a fast method for synthesizing small AgNPs with high potential to use in the clinic.

“…The literature presents numerous examples of obtaining bimetallic nanoparticles by means of physical and chemical methods (Dobrucka & Dlugaszewska, 2018). However, these methods have certain disadvantages; for example, they use costly and toxic reagents or aggressive physical treatments (Loshchinina et al, 2018). Therefore, more attention has been given to the biological methods of synthesizing nanoparticles with the use of bacteria, fungi or algae.…”

Due to the search for new methods of producing bimetallic nanoparticles, in this work, we have conducted a biological synthesis of Au-CuO and CuO-ZnO nanoparticles using Cnici benedicti. The synthesized Au-CuO and CuO-ZnO nanoparticles were also analyzed in terms of their antibacterial activity, as well as their influence on cell viability, using two specific cell lines: C6 rat brain glioma (ATCC® CCL-107™) and T98G human glioma (ATCC® CRL-1690™). The studies carried out by means of Atomic Force Microscopy helped to determine the presence Au-CuO nanoparticles whose size was about 13 nm. The size of CuO-ZnO nanoparticles was about 28 nm. The obtained nanoparticles showed cidal activity against glioma cells depending on the concentration of the substance and the time of culture. In the first stage, the nanoparticles limited the ability to divide cells; then, they blocked the cell cycle in the G2 – M phase, and finally led to massive cell death. The antimicrobial activity studies showed that Au-CuO nanoparticles inhibited the growth of microorganisms at lower concentrations than CuO-ZnO nanoparticles, and both kinds of nanoparticles showed excellent cidal properties.
