Introduction to nanotechnology - What is Nanotech
Nanotechnology is the latest advancement in the world of sciences. It refers to the constructing and engineering of the systems ion function at very micro level or we can say at atomic level. It is used to advance the present systems by implementing the new concepts related to the particular field. It uses bottom up approach to build high performance products as compared to the current market products. it is also called as general purpose technology because it has a significant influence in almost all the industries of the society in different manner. Its diversify the current extensions of the developed objects to the next level of development.
Description of working:
Nano is one billionth part of the meter in comparison to the normal carbon bond length. Complexity of engineering is increases but the Space between the molecules of an atom can be decreased or even removed with the help of nanotechnology. Two major approaches are used while working with nanotechnology
Bottom up approach
In the bottom up approach different materials and devices are constructed from molecular components of their own which are not required to assemble by an external source. They chemically assemble themselves by recognizing the molecules of their own breed. two or more components can be combined to form a new one or to be used as whole. some of the examples of molecular self assembly are Watson crick base pairing. and enzyme substrate.
Top down approach.
In top down approach nano objects and materials are created by larger entities without bouncing its atomic reactions usually top down approach is practiced less as compared to the bottom up approach.
Two other approaches are also used but are not widely famous. these approaches are named as.
Functional approach is used to build the objects regardless of their assembly or we can say on the basis of their functionality. Molecular electronics and synthetic chemical techniques are the example of functional approach.
Biomemtic approach uses the biological methods and natural systems. Biomineralization is an example of the Biomemtic approach.
Working and Impact
Nano technology deals with the development of machines and new components at cellular scale. Its possibilities if viewed are limitless. Just simply imagine the devices and machines such as nano assembler which assembles the molecules at extremely fast and atomic level. We can see the depiction of nano technology almost every where in the world of fiction. As mentioned earlier nano technology has great impact in almost every filed of life. In literature we can see the example of smart paint which is used to change the color scheme of the color coated substances. This was formed in the result of implementation of nanotechnology. Other example of nanotechnology is the advancement in desktop of the computer system, pads are now imbedded into your wrists and you can easily carry your systems any where. It also has great impact in the computer world and artificial intelligence. It can be possible with the help of nanotechnology to engineer a computer at molecular scale.
Future of nanotechnology
Nanotechnology will be the major technology in development of every machine in coming years. The industries which provide advancements in the objects are already formulating the advancements in the nanotechnology. In the immediate future nanotechnology will be having variant applications in the modern world of sciences .most prominently in the filed of medicine, to introduce the colony of nanaomachines into patient’s body for repairing surgical wounds.
