“…There was no peak located around 560 nm, indicating the absence of nanoparticle aggregation (Kora et al 2010;Velmurugan et al 2015). Similar SPR was observed for AgNPs synthesized using the aqueous extract of Prunus yedoensis (Velmurugan et al 2015), Clerodendrum phlomidis (Sriranjani et al 2016), and Dioscorea alata (Pugazhendhi et al 2016). The stability of the OPE-AgNPs synthesized under the optimized condition was analyzed by storing the samples at a temperature of ∼30°C for 6 months.…”

“…Figure 1d shows the spectral data for OPE-AgNPs at different mixing ratios of OPE and 1 mM AgNO 3 solution (1:1 to 1:10). At increasing OPE concentration, we noted an increase in SPR up to 1:5 ratio whereas at higher concentration, there was a sharp reduction and broadening of SPR around 435 nm and a small precipitation in reaction mixture was observed (see also Kora et al 2010;Venkatpurwar and Pokharkar 2011;Velmurugan et al 2015). Considering the above results, the optimal parameters were incubation at room temperature, initial pH 4.5, AgNO 3 concentration of 1.0 mM, and OPE/AgNO 3 ratio 1:5, and then they were used in subsequent experiments.…”

“…The green synthesis of AgNPs garnered wide interest owing to its instinctive features such as usage of natural resources, rapidity, simplicity, eco-friendliness, and low cost as compared to other conventional methods (Kanchi et al 2014;Velmurugan et al 2015;Ahmed et al 2016;Benelli 2016a, b). Other advantages of green nanotechnology include well-defined, controlled size of the nanoparticles and devoid of contaminants, thus the process is easy to scale up (Mittal et al 2013;Makarov et al 2014;Ahmed et al 2016).…”

“…Other advantages of green nanotechnology include well-defined, controlled size of the nanoparticles and devoid of contaminants, thus the process is easy to scale up (Mittal et al 2013;Makarov et al 2014;Ahmed et al 2016). Recently, the green synthesis of AgNPs has been proposed, relying on microorganisms (Syed and Ahmad 2012;Mittal et al 2013), plant extracts (Velmurugan et al 2015), including fruit peels (Kaviya et al 2011), and leaf extracts. Good examples of tested plant species are Azadirachta indica (Nazeruddin et al 2014), Delonix elata (Sathiya and Akilandeswari 2014), Tephrosia purpurea (Ajitha et al 2014), Argyreia nervosa (Saratale et al 2017), and many others (see Benelli 2016a for a recent review).…”

Process byproducts from the fruit industry may represent a cheap and reliable source of green reducing agents to be used in current bio-nanosynthesis. This study reports the use of orange (Citrus × clementina) peel aqueous extract (OPE) for one-pot green synthesis of silver nanoparticles (AgNPs) with high effectiveness against various microbial pathogens as well as rat glial tumor C6 cells. The effects of various operational parameters on the synthesis of AgNPs were systematically investigated. The morphology, particle size, and properties of synthesized AgNPs were characterized using UV-visible spectroscopy, x-ray diffraction, x-ray photoelectron spectroscopy, field emission scanning electron microscopy, energy-dispersive x-ray spectroscopy, and Fourier transform infrared spectroscopy. High-resolution transmission electron microscopy shows that the nanoparticles are mostly spherical in shape and monodispersed, with an average particle size of 15-20 nm. Notably, the OPE-synthesized AgNPs were stable up to 6 months without change in their properties. Low doses of OPE-AgNPs inhibited the growth of human pathogens Escherichia coli, Bacillus cereus, and Staphylococcus aureus. The minimum inhibitory concentration and minimum bactericidal concentration of AgNPs against selected pathogenic bacteria were determined. OPE-AgNPs exhibited strong antioxidant activity in terms of ABTS (2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid)) radical scavenging (IC 49.6 μg/mL) and DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging (IC 63.4 μg/mL). OPE-AgNPs showed dose-dependent response against rat glial tumor C6 cells (LD 60 μg/mL) showing a promising potential as anticancer agents. Overall, the current investigation highlighted a cheap green technology route to synthesize AgNPs using OPE byproducts and could potentially be utilized in biomedical, cosmetic, and pharmaceutical industry.

Towards the future of green, sustainable and renewable products the suggestion of using the agriculture biomass in the coming decades got increased. Biomass material is one of the important sources of alternative material for the production of biocomposite products. An increasing global awareness about environmental issues is acting as the driving force behind the utilization of biomass material as valuable products. Bio-waste materials (agricultural waste) have been recognized as an ecological burden for the society they stimulated new gateways for the production of renewable, low cost and sustainable adsorbents for water treatment applications. In the area of water purification, nanotechnology offers the possibility of an efficient removal of pollutants and bacteria. Adsorption has proved that it is the best process of water treatment technologies, because of its significant advantages. Different modification methods of waste-based adsorbents, have also been presented to highlight and discuss the key advancements on the preparation of novel adsorbents using agricultural "agro-waste". Adsorption mechanisms responsible for pollutants removal by waste-based adsorbents have also been discussed. It also focuses on the computational aspects of binding of biomolecules to nanoparticles (NPs) and some of the applications of the biosynthesized NPs as water purification. The nature acts like a large ''bio-laboratory" comprising of plants, algae, fungi, yeast, etc. which are composed of biomolecules. These naturally occurring biomolecules have been identified to play an active role in the formation of nanoparticles with distinct shapes and sizes thereby acting as a driving force for the designing of greener, safe and environmentally benign protocols for the synthesis of NPs. The biosynthesis of NPs using waste materials will help researchers not only to design safer nanomaterials but also to promote the understanding of health and safety considerations of NPs. Useful materials can be produced easily even at reasonable scale because the biomaterial based routes eliminate the need to use toxic chemicals. The aim of this review is to summarize the adsorption capacities for organic and inorganic pollutants by different bio-waste-based adsorbents.
