Nanotechnology is nothing new. Nature perfected the art of nanotechnology. We are just learning the possibility from the nature. The iridescent colors of peacock feather (refer Figure 1), the stiff and tough seashell, self-cleaning lotus leafs are remarkable example of nanotechnology from Nature. Nanotechnology provides us the ability to manipulate or engineer at atomic level for superior macro or real life applications. This report provides a brief overview of nanotechnology and applcations

    • Nanotechnology and Applications – A Brief Overview Dr Raj C Thiagarajan Technical Director ATOA Scientific Technologies Pvt Ltd** 204, Regent Prime Business Park, 48 Whitefield Main Road, Whitefield, Bangalore 560066, India. Raj@atoastech.com, www.atoastech.com. Nanotechnology is nothing new. Nature across various industries for breakthroughperfected the art of nanotechnology. We are products. For example, we know fromjust learning the possibility from the nature. The technology history and how Silicon transformediridescent colors of peacock feather (refer the electronics industry in big way with fasterFigure 1), the stiff and tough seashell, self- transistors. However, graphene sheets (Figurecleaning lotus leafs are remarkable example of 2), a planner arrangement of carbon atoms, cannanotechnology from Nature. Nanotechnology revolutionize the electronics industry with itsprovides us the ability to manipulate or ballistic electron conduction for superfastengineer at atomic level for superior macro or electronics. Similarly, carbon nanotube providesreal life applications. superior modulus and strength properties for Nano composites. Refer Figure 3 for a typical carbon nano tube bundle, and these provide exceptional mechanical, flow and electrical properties. Figure 2. A Graphene sheet: An atomic layer thick graphene for superfast electronics.Figure 1. Iridescent Color of peacock feather:Nature makes these brilliant colors by a Nano level structure, the structural color. Technically, Nanotechnology is aboutmanipulating matter below 100 nanometers.One good example is carbon atom, wherein,you can make diamond or carbon black byarranging the carbon molecules in a structuredcrystal for diamond or random amorphousarrangement for carbon black. This ability to Figure 3. Carbon nanotube bundles forengineer at Nano scale can span applications superior stiffness and transport properties.

Nature perfected nano technology by evolution over millions of years. Current technology provides us the ability to engineer at nano meter level to mimic nature and develop nano technology enabled products. Nano technology will further fuel the next economic growth and career opportunities. ***** * About the Author: Dr Raj is MD of ATOA Scientific Technologies.
