Biochemistry the chemistry of life.It is tht science tht has made DNA (even a lay men now knows the fulform of DNA ) well jokes apart,it deals with those molecules and chemicals thaat governs us from within. It is about how chemistry can exist somewhere we can never expect it to exist-our very own body. Biochemistry is,in simple words,how life forms are governed by chemistry..and how important certain bi-molecules (as they are called) are.....!!!!!!!!!!

About nano

Nanotechnology is the application of science and engineering at the atomic scale. It facilitates the construction of new materials and devices by manipulating individual atoms and molecules, the building blocks of nature. Nanotechnology enables the atom-by-atom design and fabrication of tiny structures that are very small, typically 1-100 nanometres, and which have new properties and powerful application in medicine and biotechnology, in energy and the environment, and in computing and telecommunications.


Nanotechnology is an extension of the discoveries and applications of quantum mechanics, which last century led to a detailed understanding of matter on the atomic scale, and to innovations such as transistors, lasers, and molecular biology. Despite the knowledge of atoms and molecules gained from quantum theory, only in the past 15-20 years were techniques developed to directly image, characterize and deliberately manipulate individual atoms and molecules. It is these techniques and their application that have led to the recent rapid advances in nano-scale science and engineering.

Nanotechnology is in its early stages of development, and much remains to be discovered. Building new and useful devices out of a few atoms or molecules is technically challenging, and occupies many of today's pre-eminent scientists and engineers in the best laboratories throughout the world. Many of the principles of how matter functions and organizes on the nano-scale – the so-called 'design rules' – have yet to be developed. A major challenge is determining how to assemble different types of nano-sized particles and devices, such as bio-molecules, nano-scale motors, and nano-electronics, into more complex systems that do new and useful things. Another challenge is connecting these tiny systems to the outside world so they can be controlled, monitored and provide useful information. These challenges are the principal focus of research activities at the National Institute for Nanotechnology, and are outlined in the NINT Research Plan.

The science of the miniature- nanotechnology, though a relatively new field is fast emerging as the 'favourite of all' kind of technological arena due to its application in almost every field, from medicine to fabrics. 'Nano' in Greek means dwarf and material, when reduced to nanodimension (10-9metre =1namometre) shows drastic changes in Physical, Chemical, magnetic, optical, mechanical and electrical properties. This promises exiting applications in bioscience, medical science, environment, electronics, cosmetics, security and variety of other fields.

Everything on this earth is made up of atoms, which are the smallest particles. The properties of everything are determined by the arrangement of the atoms. Thus, if atoms in coal are rearranged, we can get diamond. At present, though scientists are able to move molecules and atoms in a mass yet they are still not able to precisely manipulate them. But in future, nanotechnology will allow as redesign easily and create what we want exactly. Further, nanomaterials would be very light, strong, transparent, and totally different from bulk material because they are a thousand times smaller than the diameter of human hair, which is around 60 microns.



The scope and application of nanotechnology is tremendous and mind-boggling. According to the scientists, 21st century would be the nanotechnology century. It is estimated that nanotechnology would revolutionize every area, be it medicine, aerospace, engineering, various industrial and technological areas, health or any other field. Nanobiotechnology can make tiny medical devices and sensors with fantastic military and civilian use. Converting sunlight into power, targeting a drug to a single malignant cell, cleaning ponds and creating sensors in the form of biochip, to be interested in the human body are some of the important landmark breakthroughs of nanotechnology. The technology has the potential to produce garments which can block chemical and biological weapons from touching the skin of a person.

Nanotechnology has many more applications. It can help detect narcotics and fingerprints of suspects in crimes. The technology can make canonized robots and repair damaged and diseased tissues. Nanobots may be made from carbon nanotubes to carry out functions like human beings. Nano- coatings are transparent, scratch- resistant and dirt repellent. Thus, it is estimated that there will be no sector of industry which will not use nanotechnology in future.

Nanotechnology is an interdisciplinary subject which essentially combines Physics, Chemistry, Bio- informatics Bio- technology, etc. Though the field is at present in infancy stage (started some 16 years ago in India), the country is making dedicated efforts not to lag behind after starting work in this field. As a result, there is a great demand for students who do their M. Tech in nanotechnology because a large number of industries and laboratories in India and overseas would lab them up. There are many exciting new fields which will open up for the nanotechnology experts including-

Health Industry research and consulting- pharmaceutical, medical, agriculture, food and beverage, environment industries.

Research and development in government, universities and private research institutes

Education and academic

Entrepreneurial, management and investment advisors in biotechnology and research and development industry.

Product development and advising.

Communication and media, interfacing of new technologies.

Many new industries emerging as a result of advances in nanotechnology


To become a successful professional in the specified field of nanotechnology, it is important that you should have an M. Tech degree in the subject. To get into an M. Tech course, you should have a degree in Physics, Chemistry or Biotechnology. The M. Tech course is of great benefit because students who come from different streams enrich each other to intensify their knowledge.

There are many institutions which have started courses in nanotechnology;
Jawaharlal Nehru Center for Advanced Scientific Research, Bangalore;
Indian Institute of Science, Bangalore;
National Physical Laboratory, Delhi;
Solid State Physics Laboratory, Delhi;
National Chemical Laboratory, Pune;
Central Scientific Instruments Organization, Chandigarh;
Defence Materials Store Research & Development Organizations, kanpur
Indian Institutes of Technology at Kanpur, Chennai, Guwahati, Delhi and Mumbai.
In addition, the Delhi and Benaras Hindu Universities (Varanasi) are also conducting research in nanotechnology. It is important to note here that although these institutions are focusing on research, there is no institute exclusively providing courses in nanotechnology.



In private sector also, there is one institute, Amity Institute of nanotechnology, Noida, which offers a two- year M. Tech degree programme. The education provided is comprehensive. Students are provided the opportunity to Get trained at reputed institutes like Solid State Physics Laboratory, National Physical Laboratory, Delhi University, Indian Institute of Technology and All India Institute of Medical Sciences, etc.

Anticipating huge gains in future, countries like USA, UK, Japan, China, Germany and France have invested a lot of funds and have also focused programme at the national level. The USA, under its National Initiatives in Nanotechnology, is planning to invest $1 trillion by 2015. The Indian Government has started a scheme "S&T Initiatives in Nanotechnology" with a starting capital fund of Rs. 100 crore for five years.

There is a growing demand for nanotechnology, you will start with a monthly salary of Rs. 20,000 to Rs. 30,000. The further rise is manifold and perks could be much more.

Nano This and Nano That
Last Updated: Monday, 14-Aug-2006 17:00:00 PDT


We've all seen articles, papers, and predictions based on Nanotubes - they seem to be everywhere these days. Here is just one prediction: "Nanofibers (nanotubes) may offer the potential for creating some astoundingly large and strong space structures; they may make the prospect of rotating orbital colonies feasible." See The Use of Nanofibers in Space Construction for one speculative view.

Over the past year or so, we have seen a myriad other varieites of nano -this and nano -that. From nanosprings and nanohorns, to nanorods and nanomesh, there are nanoscale whosits and nanoscale whatsits gallore. Why, on Google alone, there are 9,950,000 pages that contain, somewhere, the word "nano"!
