“…Some of the solid toxic chemicals used as reducing agents are non-biodegradable and are potentially harmful to the environment and biological systems [7,8]. The green synthesis always benefits and prefers the chemical and physical synthesis in order to prevent dangerous by-products [9]. Therefore, developing capable and environment-friendly processes to synthesise silver nanoparticles is one of the most challenging tasks in nanotechnology.…”

In bionanotechnology, nanoparticles synthesis using biological samples is a broadly used technique as it confers lesser toxicity than chemical methods. Leaf extract of Piper colubrinum Link. was used to synthesise green mediated silver nanoparticles (AgNPs). The confirmation and stability of green synthesised silver nanoparticles by UV-visible spectroscopy showed an absorption peak at 410 nm. The synthesised nanoparticles characterised by Fourier transformed infra-red spectroscopy exhibited possible involvement of various functional groups and bio capping of AgNPs and the crystal structure was confirmed by X-ray diffraction data. Further, the size of synthesised silver nanoparticles was confirmed using transmission electron microscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and atomic force electron microscopy. The spectroscopic and microscopic analysis confirmed the successful synthesis of AgNPs by P. colubrinum extracts acting as strong reducing agents. Our results showed that reducing the silver nitrate with plant extracts formed sphereshaped AgNPs with distances in the range of 10-50 nm. XRD analysis revealed the crystal-like nature of the nanoparticles with face-centred cubic structure, and the peaks of the XRD pattern were parallel to (111), ( 200), (220), and (311) planes. The synthesised AgNPs showed the potential antibacterial activity against foodborne pathogens Escherichia coli and Staphylococcus aureus. Spectrophotometric analysis of dye degradation was confirmed the catalytic activity of synthesised AgNPs. The results of the study revealed potential of phyto-synthesised AgNPs act as catalysts and is a simple and cost effective and efficient approach.

“…The cells were incubated at 37 °C and 5% CO 2 during the experiments. Later, the cells were treated with Trypsin-EDTA (0.25%) at ~75–80% assemblage and implanted in 96-well plates at a density of 5 × 10 3 cells/well for the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (Methylthiazolyldiphenyl-tetrazolium bromide; MTT) colorimetric assay [ 2 , 24 ].…”

“…The degree of freedom of electrons dictates the movement of underlying electrons in the structures that govern the myriad differential applications from electronics to the bio-medical field [ 1 ]. On the contrary, the silver nanoparticles (AgNPs) are metallic nanostructures with a huge surface-to-volume ratio and possess the number of surface electrons and overall surface energy at their surfaces [ 2 , 3 ]. It has been extensively reported that owing to the huge amount of surface electrons and surface energy on the nanoparticle surface, the effective interface of the silver nanoparticles with their biological counterparts increases exponentially [ 4 ].…”

At present, the potential role of the AgNPs/endo-fullerene molecule metal nano-composite has been evaluated over the biosystems in-vitro. The intra-atomic configuration of the fullerene molecule (C60) has been studied in-vitro for the anti-proliferative activity of human breast adenocarcinoma (MDA-MB-231) cell lines and antimicrobial activity against a few human pathogens that have been augmented with the pristine surface plasmonic electrons and antibiotic activity of AgNPs. Furthermore, FTIR revealed the basic vibrational signatures at ~3300 cm−1, 1023 cm−1, 1400 cm−1 for O-H, C-O, and C-H groups, respectively, for the carbon and oxygen atoms of the C60 molecule. NMR studies exhibited the different footprints and magnetic moments at ~7.285 ppm, explaining the unique underlying electrochemical attributes of the fullerene molecule. Such unique electronic and physico-chemical properties of the caged carbon structure raise hope for applications into the drug delivery domain. The in-vitro dose-dependent application of C60 elicits a toxic response against both the breast adenocarcinoma cell lines and pathogenic microbes. That enables the use of AgNPs decorated C60 endo fullerene molecules to design an effective anti-cancerous drug delivery and antimicrobial agent in the future, bringing a revolutionary change in the perspective of a treatment regime.

“…Due to the importance of food packaging, many authors have investigated different nanoparticles types recently ( Biswas et al, 2020 ; Carbone et al, 2016 ; Sharma et al, 2021 ). Biswas et al, used green route synthesised silver nanoparticles (AgNPs), using Garuga pinnata leaf, a natural, nutritious drink for the tender coconut water ( Biswas et al, 2020 ). This drink is used widely as pharmaceuticals and nutraceuticals, contributing to the fast growth in the functional food industry.…”

“…This drink is used widely as pharmaceuticals and nutraceuticals, contributing to the fast growth in the functional food industry. Their work found that the interaction of silver nanoparticles (AgNPs) with DNA assists in identifying and addressing the degradation process while considering prevention from microbial attack and making the coconut water a potential functional food entity ( Biswas et al, 2020 ). Sobhan et al found that a compelling conductive antimicrobial film for smart food packaging was employed when developing silver integrated nanocomposite film based on cellulose nanofiber (CNF) and activated carbon (AC) ( Sobhan et al, 2020 ).…”
