“…So far, a number of techniques are available for Ag-NP synthesis; although most of them are expensive, complicated, and involve the use of hazardous chemicals [8]. Conversely, the biological techniques are considered as an alternative and advancement over other methods as it involves natural reagents such as sugars, biodegradable polymers, plant extracts, and microorganisms [4,[9][10][11][12][13][14][15][16][17][18][19]. In this context, the mangrove plant, Ceriops decandra (Griff.)…”

Objective: The objective of this study was to find out the antibacterial activity of the silver nanoparticles (Ag-NPs) using a low-cost green synthesis approach for the formulation of Ag-NPs applying polysaccharide extracted from the fruits of a mangrove plant of Sundarban. Methods: Fresh and healthy fruits were collected from Ceriops decandra plant. Sufficient amount of carbohydrates was extracted from those fruits and the physicochemical characterization of the polysaccharide was analyzed by gas chromatography–mass spectrometry and Fourier-transform infrared spectrophotometry. The respective polysaccharide was further applied to generate the Ag-NPs which were characterized by UV visible, dynamic light scattering, transmission electron microscopy, EDAX, and X-ray diffraction. The antibacterial efficacy of the Ag-NPs was also determined against some pathogenic Gram-negative and Gram-positive bacteria using the microdilution method. Results: Glucose and galactose are the major monomers among the extracted carbohydrates. Various types of spectral analysis confirmed the formation of Ag-NPs. The green synthesized Ag-NPs have the average diameter of about 28 nm. Furthermore, the green synthesized Ag-NPs exhibited strong antibacterial activity against some pathogenic Gram-positive (L. cytomonogenes, Bacillus Subtilis, and Staphylococcus aureus) and Gram-negative (Salmonella typhimurium and Escherichia coli) bacteria. Conclusion: The green synthesis of Ag-NPs using plant polysaccharide was an environment-friendly and cost-effective method as compared to the conventional physical and chemical synthesis techniques.

“…The most important role of proteins is that they are able to reduce iron and aid as capping agents to stabilise the Fe-NPs. This has been observed in the formation of different metal nanoparticles using fungal extracts from Alternaria alternata (Baharvandi et al 2015;Sarkar and Acharya 2017) and other species (AAAj and Azzah 2015).…”

In this study, the extract from endophytic Fusarium proliferatum was used to synthesise iron nanoparticles (Fe-NPs). The properties of the biogenically synthesised Fe-NPs were then characterised by field emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDX) and Fourier transform infrared spectroscopy (FTIR). The efficacy of the synthesised Fe-NPs in decolourizing triphenylmethane dyes was evaluated. Results revealed that fungal extract from F. proliferatum was successfully used to synthesise Fe-NPs. The Fe-NPs produced were 20-50 nm in size, and consist of substantial elemental Fe content (14.83%). The FTIR spectra revealed the presence of amino acids and proteins on the surface of the Fe-NPs, confirming the biogenic synthesis of the Fe-NPs. When tested for decolourisation, the Fe-NPs were most effective in decolourising Methyl Violet (28.9%), followed by Crystal Violet (23.8%) and Malachite Green (18.3%). This study is the first few to report the biogenic synthesis of Fe-NPs using extracts from an endophytic Fusarium species and their corresponding dye decolourisation activities.

“…The introduction of Ag particles to F. oxysporum, brought about the release of nitrate reductase ensuing development of exceedingly stable Ag NPs in solution [26]. Nano-platinum has been incorporated by the culture filtrate of Alternaria alternata, and the platinum NPs were characterized by various spectroscopic investigations (particle size 2-30 nm, spherical and triangular found the O-H stretching, C-H stretching (proteins and other organic residues), amide I (polypeptides) amide III bands (the random coil of protein)) [27]. The synergistic action of selenium NPs and the fungal C. albicans was observed after combination of selenium NPs with chitosan and fungi was used as reductive agent [28].…”

Nanotechnology is a developing branch of pharmaceutical sciences wherein the particles extend in nanosizes and turn out to be more responsive when contrasted with their unique counter parts. In the past numerous years, the utilization of synthetic concoctions and physical strategies were in mould; however, the acknowledgment of their toxic impacts on human well-being and condition influenced serious world view for the researchers. Presently, green synthesis is the watch word for the combination of nanoparticles (NPs) by plants or their metabolites. This innovation is particularly compensating as far as decreasing the poisonous quality caused by the conventionally integrated NPs. In this review, we cover the perspectives by which metal particles can be integrated from green methods in the perspective of green methods utilized in the NPs combination. In the green strategies, plant metabolites and natural substances are utilized to orchestrate the NPs for the pharmaceutical and other applications. Some characterization methods are also reviewed along with applications of NPs.
