“…The plasmonic nanoparticles are quite distinguished from other magnetic, polymeric, and semiconductor nanoparticles because of their unique surface plasmon resonance [ 65 ]. The position of the SPR peak generally depends on the shape, state of aggregation, and particle size of the nanoparticles [ 65 , 66 , 67 , 68 ]. In this study, the initial physical observation of color change in colorless silver nitrate solution with the addition of Cynara cardunculus extract confirmed the biosynthesis of polyphenol capped AgNPs.…”

In terms of reduced toxicity, the biologically inspired green synthesis of nanoparticles has emerged as a promising alternative to chemically fabricated nanoparticles. The use of a highly stable, biocompatible, and environmentally friendly aqueous extract of Cynara cardunculus as a reducing and capping agent in this study demonstrated the possibility of green manufacturing of silver nanoparticles (CC-AgNPs). UV–visible spectroscopy validated the development of CC-AgNPs, indicating the surface plasmon resonance (SPR) λmax band at 438 nm. The band gap of CC-AgNPs was found to be 2.26 eV. SEM and TEM analysis examined the surface morphology of CC-AgNPs, and micrographs revealed that the nanoparticles were spherical. The crystallinity, crystallite size, and phase purity of as-prepared nanoparticles were confirmed using XRD analysis, and it was confirmed that the CC-AgNPs were a face-centered cubic (fcc) crystalline-structured material. Furthermore, the role of active functional groups involved in the reduction and surface capping of CC-AgNPs was revealed using the Fourier transform infrared (FTIR) spectroscopic technique. CC-AgNPs were mostly spherical and monodispersed, with an average size of 26.89 nm, and were shown to be stable for a longer period without any noticeable change at room temperature. Further, we checked the antifungal mechanism of CC-AgNPs against C. auris MRL6057. The minimum inhibitory concentrations (MIC) and minimum fungicidal concentrations (MFC) were 50.0 µg/mL and 100.0 µg/mL respectively. The cell count and viability assay confirmed the fungicidal potential of CC-AgNPs. Further, the analysis showed that CC-AgNPs could induce apoptosis and G2/M phase cell cycle arrest in C. auris MRL6057. Our results also suggest that the CC-AgNPs were responsible for the induction of mitochondrial toxicity. TUNEL assay results revealed that higher concentrations of CC-AgNPs could cause DNA fragmentation. Therefore, the present study suggested that CC-AgNPs hold the capacity for antifungal drug development against C. auris infections.

“…The biosynthesis of AgNPs using plant extracts instead of synthetic chemical reagents as the reducing, capping and stabilizing agents is one of the most commonly used green methods. Diverse plants such as Givotia moluccana [11], Rhodiola rosea [10,12], Corylus avellana [2], Oyster mushroom [13], Guettarda speciosa [14], Hagenia abyssinica [15], Syzygium cumini [16], Cassytha filiformis [17], Bryophyllum pinnatum [18], and Acacia cyanophylla [19] have been successfully used to synthesize AgNPs. This approach has the advantages of being cost-effective, environmentally friendly, non-toxic and large-scale production of AgNPs.…”

The green synthesis of silver nanoparticles (AgNPs) using a water extract of Ginger (Zingiber officinale) root by microwave irradiation and its antibacterial activities have been reported. However, AgNPs prepared from different parts of ginger root water or ethanol extract by ultrasound synthesis and their antioxidant activity and whether the biogenic could be used to catalyze the reduction of hazardous dye are unknown. This study concentrated on the facile green synthesis of AgNPs prepared from different parts (unpeeled ginger, peeled ginger, and ginger peel) of ginger root water or ethanol extract by the ultrasound-assisted method. We studied their antioxidant activity and catalytic degradation of hazardous dye Direct Orange 26 (DO26) and Direct Blue 15 (DB15). The surface plasmon resonance (SPR) peak of AgNPs was at 428–443 nm. The biogenic AgNPs were approximately 2 nm in size with a regular spherical shape identified from TEM analysis. The ethanol extracts of dried unpeeled ginger and peeled ginger, fresh peeled ginger and ginger peel. The Z. officinale AgNPs synthesized by dried unpeeled ginger ethanol extract showed the best antioxidant activity. Their scavenging activities were significantly better than BHT (p <0.05). The different parts of ginger extracts showed no catalytic degradation activities of DB15 and DO26. Still, the synthesized Z. officinale AgNPs exhibited good catalytic degradation activities, while their ability to catalytic degradation to DB15 was better than DO26. In the additive ratio of 3 mL DB15, 0.1 mL NaBH4 and 0.1 mL AgNPs, the degradation rates of DB15 (or DO26) at 15 min, 30 min and 60 min were only 1.8% (0.9%), 2.8% (1.4%) and 3.5% (1.6%) in the absence of AgNPs. When adding Z. officinale AgNPs prepared from dried ginger peel ethanol extract or fresh ginger peel water extract, the degradation rates of DB15 sharply increased to 97% and 93% after 30 min, respectively. In conclusion, ginger extract has good antioxidant properties. Z. officinale AgNPs biosynthesis from ginger extract exhibit excellent catalytic degradation activities, especially for the ginger peel extract. They have application value in the treatment of textile effluents and provide a new idea and method for the comprehensive development and utilization of ginger resources.

The present study is carried to establish and compare the mycogenic silver nanoparticles (AgNPs) and zinc oxide nanoparticles (ZnONPs) synthesizing ability of two fungi, Aspergillus niger and Fusarium pallidoroseum. A 2 mM solution of silver nitrate and zinc nitrate hexahydrate is used as the precursor solution for the synthesis of silver and zinc oxide nanoparticles respectively using 1 g and 100 mg fungal biomass per 100 mL of the precursor solution. The synthesis of nanoparticles is preliminarily confirmed by UV-Vis Spectroscopy and further characterization is done through the Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive X-Ray (EDX), Dynamic Light Scattering (DLS), Fourier Transform Infra-Red (FTIR), and Inductively Coupled Plasma Mass Spectrometry (ICPMS) to characterize the nanoparticles in terms of shape, size, and concentration. The particles synthesized by using 100 mg fungal biomass are much agglomerated and bulky in size. The study concludes that 1 g F. pallidoroseum biomass showed much efficacy toward synthesizing fine-sized ZnONPs as compared to A. niger, whereas, although the AgNPs synthesized by A. niger are more monodispersed with least agglomeration, the efficacy of A. niger and F. pallidoroseum is found to be mostly comparable in synthesizing AgNPs.
