Nanotechnology studies the various phenomena of physio-chemical procedures and biological properties for the generation of nanosized particles, and their rising challenges in the various sectors, like medicine, engineering, agriculture, electronic, and environmental studies. The nanosized particles exhibit good anti-microbial, anti-inflammatory, cytotoxic, drug delivery, anti-parasitic, anti-coagulant and catalytic properties because of their unique dimensions with large surface area, chemical stability and higher binding density for the accumulation of various bio-constituents on their surfaces. Biological approaches for the synthesis of silver nanoparticles (AgNPs) have been reviewed because it is an easy and single-step protocol and a viable substitute for the synthetic chemical-based procedures. Physical and chemical approaches for the production of AgNPs are also mentioned herein. Biological synthesis has drawn attention because it is cost-effective, faster, non-pathogenic, environment-friendly, easy to scale-up for large-scale synthesis, and having no demand for usage of high pressure, energy, temperature, or noxious chemical ingredients, and safe for human therapeutic use. Therefore, the collaboration of nanomaterials with bio-green approaches could extend the utilization of biological and cytological properties compatible with AgNPs. In this perspective, there is an immediate need to develop ecofriendly and biocompatible techniques, which strengthen efficacy against microbes and minimize toxicity for human cells. The present study introduces the biological synthesis of silver nanoparticles, and their potential biomedical applications have also been reviewed.

Nowadays, nanoparticles are gaining enormous importance in a wide variety of disciplines due to their unambiguous physical and chemical properties. There are lots of physical and chemical approaches available for the synthesis of metal nanoparticles. But there are certain disadvantages associated with these methods, such as adsorption of hazardous toxins on the surface of the material, high capital investment, high manufacturing energy demand, etc., which make their effective implementation almost impossible. An alternative method of synthesizing nanoparticles to avoid the aforementioned disadvantages is to use different parts of the plant under aqueous conditions. Plant-mediated approach for the synthesis of nanoparticles is becoming increasingly popular due to its faster reaction rate, easily affordable, eco-friendly nature and rich diversity of plants. Chemical compositions of plant extracts are examined using the liquid chromatography-mass spectrometry technique. Noble metals such as Silver, Gold, Iron, Copper, Platinum, Zinc, Palladium, and their oxides are used for the fabrication of metal nanoparticles, due to their enormous potential applications. In a single-step green synthesis process, the phytochemical constituents which are present in plant extract reduce metal salts into metal nanoparticles. This article gives an overview of plant-mediated synthesized metal and metal oxide nanoparticles and their characterization by using different techniques, together with their properties and applications in numerous fields.

Five- and six-membered N-heterocyclic compounds play an important role in medicinal chemistry and the development of new drugs. There is a constant demand for the development of novel biologically potent compounds, and there is also an increasing pressure to develop alternative and more sustainable synthetic methodologies following the Green Chemistry principles. Thus, the present review aims to compile the latest progress in the use of ultrasound irradiation in water conditions to mediate the synthesis of five- and six-membered N-heterocyclic compounds in an environmentally benign manner.

The starting of DDT production during World War II also signalized the beginning of a very rapid increase in pesticide use. Pesticides applied in the control of invertebrates are known as insecticides. On the other hand, vertebrates are controlled by rodenticides, which are used for killing rodents etc.; moreover, avicides are applied to repel birds, and piscicides are used in fish control. Herbicides are the most important in agriculture and are used for plant cultivation, moreover, fungicides are useful in killing fungi. Bactericides are used against bacteria, slimicides are used against slime-causing organisms in water, and algicides against algae. Many pesticides which were used in agriculture in the last 30-40 years are no longer authorised and have been replaced by pesticides on a non-chemical basis. Currently, the aim of the REACH Regulation in the European Union is to provide better protection for humans and the environment from possible chemical risks and to promote sustainable development. The European Chemicals Agency, established under this regulation and based in Helsinki, is responsible for managing the technical, scientific, and administrative aspects of REACH and for ensuring consistency in its application (www.europarl.europa.eu). In order to enhance the level of protection of human health and the environment, the same criteria for identifying labels for describing chemical hazards should be used throughout the EU and the world (www.europarl.europa.eu). This contribution briefly refers to the pesticides classification and their most commonly used detoxification.
