Nanotechnology Future Will Blow your Mind

Nanotechnology Spray

Miniaturisation is the buzz word today. Nanotechnology is not simply miniaturisation. It is much more in frontier science, with its scope and application limitless and mind boggling. "1000 compact discs in a wrist watch",that is how Prof. CNR Rao, a noted scientist, terms it.

Nanotechnology is a term used for describing the creation and exploitation of materials with structural features in between those of atoms and bulk materials, with at least one dimension in the nanometer range (1nm - 10-9 m). Properties of materials of nanometric dimensions are significantly different from those of atoms or bulk materials. A suitable control of the properties of nanometer-scalestructures can lead to new science as well as new products, devices and technologies.

There has been a tremendous growth of nanoscience and technology in the last decade, primarily due to the availability of new methods of synthesis of nanomaterials as well as tools of characterisation and manipualtion. Several innovative methods of synthesizing nanoparticles and nanotubes and their assemblies are now available. There is a better understanding of size-dependent electrical, optical and magnetic properties of individual nanostructures of semi-conductors, metals and other materials. Besides the established techniques of electron microscopy, crystallography and spectroscopy, scanning probe microscopes have provided powerful tools for the study of nanostructures.

Novel methods of fabrication concepts are being constantly discovered. Nanostructures have also been ideal for computer simulation and modelling with their size being sufficiently small to accommodate considerable rigour in treatment. Ordered arrays or superlattices of nanocrystals of metals and semiconductors have been prepared by several researchers. Nanostructured polymers formed by the ordered self-assembly of triblock copolymers and nanostructured high-strength materials are other examples. Prototype circuits involving nanoparticles and nanotubes for nanoelectronic devices have also been fabricated. Quantum computing has made a good start and appropriate quantum algorithms have been developed. Theory and computer simulation are highly useful in understanding nanosystems.

Everything in nanoscience is not new. Many existing technologies employ nanoscale processes, catalysis and photography being well known examples. Our capability to synthesize, organise and tailormake materials at the nanoscale is, however, of very recent origin. The immediate goal of science and technology of nanomaterials among other things should be to fully master the synthesis of isolated nanostructures (building blocks) and their ensembles and assemblies and desired properties; explore and establish nanodevice concepts and systems architecture; generate new classes of high performance materials, including biology-inspired systems; connect nanoscience to molecular electronics and biology and improve known tools while discovering better tools of investigation of nanostructures.

Some of the potential applications of nanotechnology of great societal and economic impact lie in the production of novel materials and devices, nanoelectronics and computer technology as well as in medicine and health care. These wide-ranging applications may indeed usher in a new trend in electronics, space, chemical energy and manufacturing industries.

Synthesis

Synthesis of nanomaterials and assembling the nanostructures into ordered arrays for rendering them functional and operational are crucial aspects of nanoscience. The materials or structures include nanoparticles, nanowires, nanotubes, nanostructured alloys and polymer, nanoporous solids and DNA chips. Besides conventional tools of characterisation such as X-ray, specialised instrumentation will be required. These include sophisticated scanning probe microscopes, high resolution electron microscopy and magnetic force microscopy.

Applications

Some of the important applications and technologies include production of nanopowders of ceramics and other materials, nanocomposites and other nanostructured high strength materials, application of nanotubes for hydrogen storage and other purposes, DNA chips and chips for chemical / biochemical assays, gene targeting or drug targeting, nanoelctronics and nanodevices.

The last one is probably the most important difficult area. Applications of this area include; new lasers, nanocomputers (based on nanotubes and other materials) defect-free electronics for future molecular computers, resonant tunneling devices, spintronics, combination of biological motors with inorganic nanodevices and nanosensors.

The subject is of great value and offers immense opportunities. It is a truly interdisciplinary area encompassing physics, chemistry, biology, materials and engineering. Interaction amongst technocrats with different backgrounds will undoubtedly create new science and in particular new materials with unforeseen technological possibilities. While there is some effort in nanotechnology in a few academic laboratories, there is a need to establish dedicated centres with required infrastructure and experimental facilities. The subject has caused excitement in the advanced as well as the developing nations and is one area where international cooperation would be highly fruitful. What is also noteworthy is that nanotechnology will benefit not only the electronics industry, but also the chemical and space industries, as well as the medicine and health care sectors.
