The worlds most advanced super Computer does not require semi-conductor chip. The human brain consists of organic molecules that combine to form a highly sophisticated network able to calculate, perceive, manipulate, self-repair, think and heel. Digital computers can certainly perform calculation much faster and more precisely than humans can, but even simple organisms are superior to computers in the other five domains.
Computer designers many never be able to design machines having all the faculties of a natural brain, but many of us think that we can exploit some special properties of biological molecules – particularly proteins – to build Computercomponents that are smaller, faster and more powerful than any other electronic device on the drawing board thus for.
The size issue is especially pressing since the 1960’s the Computer industry has been compelled to make the individual components on semiconductor chips smaller and smaller in order to manufacture larger memories and more powerful processors economically. If the trend towards miniaturisation continuous the size of a single large gate will approach the size of molecules by about 2030. But unfortunately for each factor of two in miniaturisation the cost of manufacturing a chip increases by five. On the other hand the use of biological molecules as active components in Computer circuitry may offer an alternative approach that is more economical. Devices fabricated from biological molecules promises compact size and faster data storage. They lend themselves to use in parallel processing computers, three dimensional memories and neural networks.
INTRODUCTION
Biomolecular electronics offer significant promise in addressing some of the interest limitations of semi conductor architectures. Molecular electronics is an emerging field that lies at the interface of chemical physics, bio physics, electrical engineering and physics, bio physics, electrical engineering and solid state science. It involves the encoding manipulation and retrieval of information at a macromolecular level in contrast to current techniques.
Molecular electronics not only represents the final technological state in the miniaturisation of the Computer circuitry, it also provides promising new methodologies for high speed signal processing, holographic associative memories and three dimensional optical memories.
As mentioned earlier the computer industries are on the process of making the individual components on semi conductor devices competitively smaller. These small chips essentially consists of arrays of switches usually of the kind known as logic gates that flip between two states designated as ‘0’ and ‘1’ in response to the changes in electric currents passing through them.
