Critical Reviews on Engineered Nanoparticles in Environmental Remediation

Abstract

Environmental contamination is one of the important issues that the world is facing today, it is always expanding and leading to the grave and harmful effect on the Earth. Nanoparticles have a diameter less than 100 nm exhibit new size-dependent properties compared with the bulk material. Engineered nanoparticles (ENPs) have unique characteristics in addition to the high surface areato-volume ratio, which may increase their toxicity relative to bulk materials. Due to the high volume production of ENPs products such as carbon nanotubes, titanium dioxide, silver, zinc oxide environmental exposure to these compounds is very common. ENPs have their unique properties and applications in the areas of medicine, food& drink, construction, automotive, textiles, energy, electronics, environment etc. The present critical review is focused on the recent development of the applications of ENPs in the environmental remediation and their toxic effects.

Synthesis and Characterization of Nanomaterials for Application in Cost-Effective Electrochemical Devices

“…Because it provides selectivity for the sensor and catalyzes the formation of the electroactive substance for detection, the enzyme is the most significant part of the enzyme electrode. The production of various materials, techniques, and applications of electrochemical enzyme-based biosensors has been the subject of several studies in the last two years [254]. Nanoforms of minerals such as silver, titanium, and zinc and their oxides are used in several kinds of toothpaste, cosmetics, sun protection, paint, clothes, and food.…”
