Introduction

Nanoscience, nanotechnology, nanoparticles and nanostructure have now become common words not only in research publications but also in daily life. Nanomaterials hold potential to make supercomputers that are small enough to be carried in a shirt pocket or machines that can repair damaged tissues by travelling through the human body. Nanostructured materials are expected to be utilized in many different applications, including sensors, optical filters, low-threshold laser, controlled drug delivery, and biological detection, to name a few.

History of Nanomaterials

Metal nanoparticles have been utilized for quite a while. Recent studies disclosed that nanoparticles are the secret of Glass Lycurgus Cup which has characteristic color and Damascus steel which utilized to make swords. It is like just accidentally developed technique to manufacture nano-objects and harness their innovative properties. However, after the development of the sophisticated device to analyze nanoscale materials, researchers are able to corroborate the development of nanotechnology, which has now become a subject of intense research.

Damascus steel was used to produce blades from about 500 AD in Damascus. These blades are recognized for their resilience, sharpness, extreme strength and the aesthetic appeal of their unique surface pattern. Many researchers tried to reveal reason behind the special properties of Damascus steel and what they found was the presence of multi-walled carbon nanotube in the material.

Glass Lycurgus Cup is the Roman period cup, i.e., fourth century AD. Modern analytic methods disclosed that Glass Lycurgus Cup comprises silver and gold nanoparticles in the ratio of roughly 7:3, with a size of 70 nm diameter. The cup demonstrates a unique color display because of the presence of these metal nanoparticles. It appears green when observed in reflected light, for instance in daylight. However, it appears red when light is propagated through it. It is now in the British museum.

Development of Nanomaterials

Nanoparticles are in the size range of 1-200 nm and demonstrate exotic catalytic, optical and electronic properties. Their properties vary with the manufacturing technique used for controlling their size and shape, thus making them interesting building blocks for nanoscale structures, assemblies and devices. Miniaturization of structures by electron-beam lithography and mechanical techniques is approaching the theoretical limits of about 50 nm. Hence, it is necessary to develop alternative methods to enable further miniaturization of chemical objects.

Nanoparticles have potential applications in many different fields. Engineered nanoparticles are specifically designed and formed with customized physical properties in order to fulfill the requirements of specific applications. They can serve as the end product, like sensor for special purposes, pharmaceutical drugs and quantum dots, or they can serve as components in end products, as in the case of carbon black in rubber products. For both purposes, the physical properties of the nanomaterials play a key role in their performance. The novel physical and chemical properties of nanomaterials pave way to interface electronic signal transduction with biological recognition events and to design advanced bioelectronic devices with innovative functions.
