ABSTRACTMethods of “green” synthesis of nanoparticles of elemental iron (zero-valent iron, NZVI), its oxides and hydroxides using natural products are reviewed. In particular, the use of biological agents such as extracts of various plants, tea, soya, table sugar and glucose, as reductants and as capping agents is shown. The techniques involved are simple, environmentally friendly and generally one-pot processes. Water disinfection using iron nanomaterials against viruses and bacteria is also examined.

: In this review, we examine ‘greener’ routes to nanoparticles of iron oxides, in the recent years; nanotechnology has emerged as a state-of-the-art and cutting edge technology with multifarious applications in a wide array of fields. Natural products or extracted from natural products. Such as different plant extracts, have been used as reductants, and as capping agents during synthesis. A very easy, efficient and environment-friendly protocol was developed to synthesize green nanoparticles (NPs) with an aqueous extract of various plant, phenolic compounds extracted from plants play a major role as a non-toxic reducing and capping agents for nanoparticle. Nanoparticles and their compounds are known to exert a strong inhibitory and microbial activity on bacteria, viruses, and fungi. In today's world, because of the epidemic of infectious diseases caused by different pathogenic bacteria and the development of antibiotic resistance. Green synthesis, characterization, and application of nanoparticles (NPs) are becoming an important challenge in nanotechnology. Green synthesis of nanoparticles is made in large quantities worldwide for a wide range of applications. This technique is very safe and environmentally friendly.

: Oxindoles are an important class of heterocyclic scaffolds widely present in natural products and bioactive compounds. For this reason, a plethora of methodologies for the stereoselective synthesis of enantioenriched oxindoles has been studied over the years. Among all the reported synthetic strategies, organocatalysis has proven to be a powerful tool for the asymmetric synthesis of this class of compounds being a step- and atom-economical, environmentally friendly, and non-toxic approach. This review will outline the application of asymmetric organocatalysis in the synthesis of chiral oxindole-based structures, relying on domino/one-pot reaction sequences in a step-economical fashion.

Abstract A highly efficient multi-component one-pot synthesis of novel 1H-imidazo[1,2-a]imidazole-3-amine and imidazo[2,1-c][1,2,4]triazole-5-amine derivatives has been developed through the reaction of easily available aromatic aldehydes, benzoyl cyanide and either 2-aminoimidazole-4,5-dicarbonitrile or 3-amino-1,2,4-triazole in pyridine under controlled microwave heating. The process is environmentally friendly, is operationally simple, with short reaction time and with high yields.

The development of different eco-friendly technologies in material synthesis is playing its role to expand their biological applications. Nanoparticles are synthesized chemically, but because of their hazardous effects, the researchers have now turned to biological systems for inspiration. There is a growing concern about the possible results of effects of chemical synthesis of nanoparticles. Therefore, the aim of this chapter is to provide an overview of how nanomaterials can be synthesized using green route to play its role in environmental sustainability as green synthesis processes are considered to be a safe alternative to routine processes due to their cost effectiveness, easy to handle, and environmentally friendly nature. In fact, it opens a new scope for phyto-chemists by discouraging the use of toxic chemicals.

Background: Owing to the importance of metallic nanoparticles, different researches and studies have been induced to synthesize them in many ways. One of the ways that paid attention last years is the green synthesis methods of nanoparticles or the so-called ''eco-friendly methods''. The most common sources that has been used for green synthesis of nanoparticles are plants, leaves, fungi and microorganisms. The green synthesis methods are widely used because they are inexpensive, usable, and nontoxic. Moreover, plant extracts are rich in reducing and capping agents. Methods: In the present review, green synthesis methods of gold nanoparticles (AuNps) using Chitosan, Klebsiella pneumoniae, Magnolia Kobus, Elettaria cardamomum (Elaichi) aqueous extract and other agents as a reducing/capping agents will be discussed in details. Moreover, we will make a comparison between different green routes of synthesis and the characterization of the obtained nanoparticles from each route. Results: The characterization and applications of the prepared GNPs from different routes are reviewed. Conclusion: The utilization of gold nanoparticles has been advocated because of their high biocomptability, administration in clinical applicability and in diverse aspects of life. It seems that plants are good candidates for nanoparticles production because they are inexpensive, available and renewable sources in addition, it is too simple to prepare extracts from them. Moreover, the great diversity in the types and amounts of reducing agents from plant extracts is responsible for the effortless generation of metallic nanoparticles of various shapes and morphologies.

Microbial Potential

The synthesis of nanoparticles (NP) using marine plants has been well developed. In recent years, few reports of NP synthesis use mangroves, which are used as bio plants for synthesis. In addition, mangroves are a renewable, sustainable and economical source compared to other marine organisms, so they can be explored effectively in the synthesis of green NPs (Green Synthesis). Therefore, this study reports on the biosynthesis of NP, especially silver nanoparticles (AgNPs) using mangrove extracts. NPs synthesized by this method are primarily spherical with promising anti-microbial potential. The biosynthesis of silver nanoparticles can be triggered by several compounds such as carbonyl, terpenoid, phenolic, tannin, flavonone, amine, amide, protein, pigment, alkaloid and other reducing agents in biological extracts capable of as reducing agents and capping agents. Marine bio-nanotechnology has great promise in nanomedicines, groceries, pharmaceuticals and industrial fabrics for the future.
