Biofabrication of gold nanoparticles (AuNPs) using the aromatic essential oils is highlighted due to its simple, economical, low toxicity, and eco-friendly nature. Essential oil of Cymbopogon flexuosus (CF), an economically valuable medicinal plant, exhibits anti-inflammatory, anti-tumor, antioxidant, and antimicrobial activities. For the first time, this research accounts for the biosynthesis, physicochemical, photocatalytic, antifungal, antibacterial properties of biogenic AuNPs, fabricated using CF essential oil collected from different altitudes (S1-Palampur, S2-Haryana, S3-Dehradun). The altitudinal disparity in the phytochemical composition of essential oils is highlighted. The average crystallite size ranged from 10 to 32 nm and was influenced by CF samples used in the synthesis. The spectroscopic outcomes revealed the involvement of bioactive reagents from CF essential oil in the fabrication and stabilization of AuNPs. The fabricated AuNPs exhibited excellent antimicrobial activities against all tested strains (Staphyloccucs aureus, Escherichia coli, Fusarium oxysporum), showing their efficacy as an antimicrobial agent to treat infectious diseases. Moreover, AuNPs exhibited excellent photocatalytic efficacy of around 91.8% for the degradation of methylene blue under exposure of direct sunlight for 3 h without the assistance of an external reducing agent. The outcomes highlight a potential economic and environmentally friendly strategy to fabricate biogenic AuNPs for diversified industrial applications where antimicrobial and photocatalytic efficacies are the key requirements.

The applications of nanoparticles (NPs) and another nanomaterial (NM) are widely increasing in various fields including biomedical and clinical sciences. Conventional methods used for the synthesis of NM have several demerits like chemical procedures producing toxic materials and physical methods being costly and forming particles of non-uniform sizes. The use of such NM has prevented their applications in biomedical fields especially in clinical applications. In order to use NPs in clinical fields, there is a need to use reliable, nontoxic and eco-friendly methods for their synthesis. The use of eco-friendly and biological methods for the synthesis of NPs and other NM has attracted the attention of nanobiotechnologists due to synthesis of such particles by using nontoxic method. The enzymatic synthesis of NPs is highly specific as this procedure results in the formation of nontoxic materials of controlled shape, size and high stability. In this chapter an effort has been made to critically review recent developments in the area of biosynthesis of several types of NM by using enzymes of diverse groups such as oxidoreductases, transferases, hydrolases, lyases and ligases. The mechanisms of enzyme catalyzedsynthesis of NPs and the reaction conditions to control their shape, size, and stability of NPs have also been described. Numerous kinds of techniques employed for the identification and characterization of NM have been discussed. The biomedical and other applications of as-synthesized NM have also been mentioned in this article.

“…They reported that all conjugated triangular NPs and naked triangular AuNPs showed enhanced antifungal properties; however, this property was not observed with any peptide ligands. In another study, Gholami-Shabani et al ( Gholami-Shabani et al, 2016 ) developed a cell-free system to generate AuNPs by using purified sulfite oxidoreductase (a fungal oxidoreductase) of Fusarium oxysporum ( F. oxysporum ). These researchers used the disk diffusion method to assess the antifungal activities of prepared NPs.…”

“…They observed strong growth inhibitory properties against all tested human pathogenic molds and yeasts, as demonstrated by inhibition zones ranging from 10 to 18 mm ( Gholami-Shabani et al, 2016 ). Collectively, it was indicated that the preparation of NPs by using a purified sulfite oxidoreductase of F. oxysporum can be effective in producing safe bioactive AuNPs, which can be effectively used in the field of medicine ( Gholami-Shabani et al, 2016 ). In Table 2 , a summary of the antifungal potentials of various MNPs and metal oxide NPs has been provided.…”
