Nanotechnology and the Sustainability: Toxicological Assessments and Environmental Risks of Nanomaterials Under Climate Change

Abstract

At present, natural resources are very limited and inadequate for increasing global population along with uncontrollable environmental pollution. The development of advanced eco-friendly technology and pollution free environment is very necessary for the current situation. Nanotechnology is playing a vital role in the development of "cleaner" environment and "greener" technologies for sustainable livelihood and environment. Nanotechnology is involved in many sectors like pharmaceuticals, agriculture, food, energy, environment, cosmetics, electronics, chemicals, and so on. There are many consumer products containing nanomaterials available in the market for ready use by human beings. Hence, human exposure to nanomaterials is possible to occur during processing at occupational level and personal usage at consumer level. At present, nanotechnology is a promising tool as it has high performance and is cost-effective in

The Synthesis of 2,2-BIS(1-INDOL-3-YL)Acenaphthylene-1(2)-Ones Using Nanocatalysis: Fluorescent Sensing for Cu2+ Ions

“…The deficiency of this metal can be caused many problems in the human body such as anemia, hair loss, increased blood cholesterol, and immunodeficiency [6][7][8][9]. Importantly, this element has been widely deployed as catalyst in organic reactions for the synthesis of heterocycle, medicinal and natural compounds via assorted methods [10][11][12][13][14][15][16][17][18][19][20][21][22][23]. The advantageous methods for determining copper ions in various samples comprise electrochemical methods such as voltammetry, colorimetric, potentiometric chromatography, atomic adsorption (AAs), techniques inductively coupled plasma (ICP), UV-Vis, and photoluminescence techniques (among them, optical methods are excellent means for measuring the copper ions due to their high selectivity, sensitivity, inexpensive nature, and a wide linear range) [24][25][26][27][28][29][30][31][32][33][34][35][36].…”
