In the last decades, antibiotics were used to treat infections caused by some Staphylococcus species, especially Staphylococcus aureus and Staphylococcus epidermidis. The widespread use of antibiotics to treat staphylococcal infections has resulted in an increase in the resistance of bacteria to antibiotics, particularly to beta-lactam antibiotics. In recent years, researchers have been working on developing new antibiotics, despite the fact that they are complex and expensive and carry a number of risks associated with drug toxicity. Using new substances that have good potential against bacterial infection without causing bacteria to become resistant to these substances is currently being researched. More research has been carried out on the effect of silver and copper nanoparticles in neutralizing staphylococcal infection in laboratory studies. The toxic effect of nanoparticles was a concern to scientists, but despite that, the studies in vivo found that there was no toxic effect at low doses of nanoparticles on rats. The findings in this field were acceptable to entice researchers to develop these substances.

“…The proposed method includes pathways of NADH dependent reductases along with shuttle quinone extracellular procedures. It was reported that depending upon the quantity of NADH formed, the synthesis of alloy of Au-Ag NPs with a variety of compounds was possible (Mubarakali et al, 2012;Bhardwaj and Naraian, 2021). The size of NPs formed has been observed to be dependent on synthesis conditions like fungal species used, temperature, pH, dispersion medium, etc.…”

Nanoscience is a rapidly growing science stream that has been one of the cost-effective and energy-efficient approaches with wide applications. Water pollution is a major issue that is increasing continuously due to anthropogenic activities and several organic and inorganic contaminants. To overcome this issue, nanoparticles (NPs) have been successfully used to treat water. These NPs possess many beneficial applications in many fields like agriculture, cosmetics, photoconductors, environmental biotechnology, glass and alloy production, solar cells, nanomedicine and drug deliveries, biosensors, food industries, etc. The properties comprising high surface area, greater chemical reactivity, and mechanical properties play a vital role in imparting such beneficiary properties. As a result, there has been an increasing demand for the synthesis of NPs. However, excess usage of NPs further creates toxic by-products. Therefore, scientists and researchers are now focussing on the biogenic synthesis of NPs. The biological routes of NP synthesis have been crucial because they are eco-friendly and environmentally safe. This chapter highlights the usage of different approaches and biogenic sources for the production of NPs. It also discusses the recent advancement in the use of biogenic NPs with respect to applications for wastewater treatment.

“…The above methods also utilized a very high temperature and pressure which is very harmful to the environment. Accordingly, the product cast is very high due to the higher order of the equipment used in these methods [7]. As a result, an environmentally friendly method is required to synthesize the NPs without utilizing any toxic components.…”

In current decade, zinc oxide nanoparticles (ZnO NPs) widely exploring owing to its versatile properties, prodigious demands in energy, beauty, healthcare sector. Therefore, the current work opted environmentally benign method to prepare ZnO NPs. In this process Aqueous Calendula officinalis L leaf extract was prepared for the reducing metal ions. The aqueous solution of zinc acetate (0.45M) were dropped at the rate of 5 ml/10 minute in the prepared extract. The ZnO NPs were successfully manufactured using a 50 ml and the aqueous solution (5 g) of Calendula leaves under constant stirring (1200 rpm) at a temperature of 600C for 2 hours. Brown coloured dried powder was obtained after three times washing. Furthermore, it characterized using different physico-chemical techniques. The spectroscopic study of synthesized ZnO NPs in distilled water, a peak observed at 355 nm. After initial confirmation of desired NPs, the FESEM generally apply to know their external assembly, which found small and big agglomerated form. The median crystalline particle size was estimated approx. ~24 nm using an X-ray diffraction (XRD) pattern. Fourier transform infrared spectroscopy (FT-IR) showed an absorption peak of the Zn–O bond between 4000 and 500 cm-1. This phyto-synthesis method for preparing the ZnO NPs using the leaf extract of Calendula officinalis L. evidenced to be superior, and environmental friendly, and these nano products shows the various applications.
