Abstract

In recent years, the use of nanoparticles has grown tremendously in various fields, including medicine, industry, agriculture, mechanics, and water and wastewater treatment. As a functional nanoparticle, Quantum dots (QDs), have recently been been introduced to the field of water and wastewater treatment 1. QDs comprising of 200 to 10,000 atoms have demonstrated great versatility due to their small diameter of 2 to 10 nm, and function as a semi-conductor nanocrystal by emitting light after excitation. The QDs characteristics are controlled by changing the molecular structure according to the individual’s desirable usage 2. The size, shape, and structure of QDs control their electrical properties and peak emission frequency 3 © 2023,Journal of Environmental Health and Sustainable Development. All Rights Reserved.
