CHAPTER 1

Introduction

1.1 Nanomaterials

N anosized particles have been existing on earth since millions of years and are being utilized since thousands of years (Buzea et al ., 2007). By definition, a nanostructure is an object that has at least one dimension equal to or smaller than 100 nanometers. There is a wide variety of nanostructures, such as nanoparticles, nonporous, nano rods, nano-wires, nano-ribbons, nano-tubes, and nano-scaffolds. The promising features of these structures are their size dependent properties (Motasim Bellah et al., 2011). Nanotechnology is the art of manipulating materials on atomic or molecular scales especially to build nano scale structures and devices. They may or may not exhibit size related characteristics that differ significantly in comparison to fine or bulk particles. They have gained a whole lot of attention in recent times due to their increasing ability to be synthesized and manipulated, along with their utility in wide areas like electronic, biomedical, pharmaceutical, cosmetics, energy, environmental, catalytic and material applications (Bernd et al ,. 2007). An estimate for the production of engineered nano materials has been 2000 tons in 2004, which has been predicted to increase 58000 tons by 2020 (Maynard et al ,.2006)

1.2 Metal oxide nanoparticles

Metal oxide nanoparticles is a special field of materials chemistry that has attracted considerable interest due to the potential technological applications of these compounds in a wide range of fields such as medicine, information technology, catalysis, energy storage and sensing [Corr et al,.2013]. Possess high surface area and high fraction of atoms that is contributing to its various fascinating properties like antimicrobial, magnetic, electronic and catalytic activity. Among the metal oxide nanoparticles, titanium dioxide nanoparticles possess a prominent status and is widely used in air and water purification and in dye-sensitized solar cell due to their oxidation strength, high photo stability and non-toxicity [Monticone et al,. 2000]. Titanium dioxide nanoparticles are being manufactured worldwide in huge amounts for a variety of applications like sunscreen and UV blocking pigments, photo catalyst and electronic storage medium. TiO2-NPS possess unique physicochemical properties in comparison to their fine particle analogs which
