Nanotechnology emerged as a scientific innovation in the 21st century. Metallic nanoparticles (metal or metal oxide nanoparticles) have attained remarkable popularity due to their interesting biological, physical, chemical, magnetic, and optical properties. Metal-based nanoparticles can be prepared by utilizing different biological, physical, and chemical methods. The biological method is preferred as it provides a green, simple, facile, ecofriendly, rapid, and cost-effective route for the green synthesis of nanoparticles. Plants have complex phytochemical constituents such as carbohydrates, amino acids, phenolics, flavonoids, terpenoids, and proteins, which can behave as reducing and stabilizing agents. However, the mechanism of green synthesis by using plants is still highly debatable. In this report, we summarized basic principles or mechanisms of green synthesis especially for metal or metal oxide (i.e., ZnO, Au, Ag, and TiO2, Fe, Fe2O3, Cu, CuO, Co) nanoparticles. Finally, we explored the medical applications of plant-based nanoparticles in terms of antibacterial, antifungal, and anticancer activity.

“…Today, various techniques are employed for water recovery and recycling (Matouq et al, 2014;Al Ansari, 2012;Ntampegliotis et al, 2006). Coagulation/flocculation, in particular, has been extensively used due to its low cost and simple operation.…”

In the current work, the application of chemical coagulation/flocculation/sedimentation, an established and low cost method, to marble processing wastewater treatment is studied, and the optimum conditions for the maximum solid waste removal are investigated. The environmental impact from the operation of a modern marble processing plant is actually important, due to the consumption of high amounts of water resulting in the production of high effluent volumes, and therefore particular efforts are made for the efficient wastewater treatment in order to recover and reuse the effluents of the process, and avoid uncontrolled discharge and disposal of solid residue from the primary wastewater treatment. For that purpose, hydrated metal salts including Al 2 (SO 4) 3. 18H 2 O, FeCl 3. 6H 2 O and FeSO 4. 7H 2 O were examined for their turbidity removal capacity under various dosages and studied in relation to the wastewater pH and electrical conductivity. Jar test results showed that FeCl 3. 6H 2 O presented the highest turbidity removal ability at doses of about 0.375 g/L, while the poorest coagulation/flocculation potential was found for FeSO 4. 7H 2 O. The findings of this study are expected to contribute to the preparation of a strategic plan for the integrated management of marble processing operations with a lower environmental footprint.

“…Under conditions of high risks and exposure failure, the repercussions can be catastrophic, causing damage or death (Anastas & Eghbali, 2010). Al Ansari (2012) said that in order to make chemicals and processes that are safe and long-lasting, the risks of accidents and damage must be kept to a minimum.…”

Important routes for the synthesis of nanoparticles include physical and chemical processes, which are typically costly and potentially dangerous to the environment. The assessment of eco-friendly chemistry or biological strategies for producing nanoparticles from plant extracts has attracted the interest of a large number of scientists in recent years. Before establishing a generally accepted method, researchers must investigate the plant-assisted synthesis of nanoparticles and their effects. It is gaining popularity because of its ability to facilitate the creation of alternative, safer, less toxic, sustainable, and environmentally friendly methods. The synthesis of novel nanoparticles with the necessary properties is mandatory for the development of cosmetics, biomedicine, biosensors, nano-biotechnology, and other applications involving antibacterial, catalytic, electronic, electrochemical, and sensing processes. Environmental and biological fields have numerous possible uses for the green synthesis of nanoparticles. It attempts specifically to decrease the use of harmful chemicals. Typically, employing biological resources, such as plants, is harmless. Also found in plants are reducing and capping agents. Here, we discuss the advancement of green synthesis of nanoparticles, the most current applications, and future perspectives.
