A basic definition: Nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced. In its original sense , 'nanotechnology' refers to the projected ability to construct items from the bottom up, using techniques and tools being developed today to make complete, high performance What is nanotechnology ?

Slide 6: 

When K. Eric Drexler (right) popularized the word 'nanotechnology' in the 1980's, he was talking about building machines on the scale of molecules, a few nanometers wide — motors, robot arms, and even whole computers, far smaller than a cell. W hen the K.Eric Completed his project and he success in that he introduce his technology to whole world. At that he the scientists richard feynman says. History & Founder of ‘Nanotechnology’

Slide 7: 

Richard feynman want to build a billion tiny factories, models of each other, which are manufacturing simultaneously. The principles of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom. It is not an attempt to violate any laws; it is something, in principle, that can be done; but in practice, it has not been done because we are too big. ( Richard Feynman, Nobel Prize winner in physics .)

Slide 8: 

Nanotechnology is sometimes referred to as a general-purpose technology. That's because in its advanced form it will have significant impact on almost all industries and all areas of society. It will offer better built, longer lasting, cleaner, safer, and smarter products for the home, for communications, for medicine, for transportation, for agriculture, and for industry in general. General-Purpose Nanotechnology

Slide 9: 

Like electricity or computers before it, nanotech will offer greatly improved efficiency in almost every facet of life. But as a general-purpose technology, it will be dual-use, meaning it will have many commercial uses and it also will have many military uses—making far more powerful weapons and tools of surveillance. Thus it represents not only wonderful benefits for humanity, but also grave risks. Dual-Use Nanotechnology

Slide 10: 

The power of nanotechnology can be capsulated in an apparently simple device called a personal nanofactory that may sit on your countertop or desktop. Packed with miniature chemical processors, computing, and robotics . Nanotechnology not only will allow making many high-quality products at very low cost , but it will allow making new nano factories at the same low cost and at the same rapid speed.. The means of production will be able to reproduce exponentially, so in just a few weeks a few nanofactories conceivably could become billions ..

Slide 11: 

Nanorobotics Definition:- Nanorobotics is an emerging field that deals with the controlled manipulation of objects with nanometer-scale dimensions. Typically, an atom has a diameter of a few Ångstroms (1 Å = 0.1 nm = 10-10 m), a molecule's size is a few nm, and clusters or nanoparticles formed by hundreds or thousands of atoms have sizes of tens of nm. Therefore, Nanorobotics is concerned with interactions with atomic- and molecular-sized objects-and is sometimes called Molecular Robotics.

PALM –TOP What are PDAs and handheld computers? PDA: Personal Digital Assistant: A small computer that literally fits in the palm of your hand. More limited than a desktop computer, but useful for calendars, address books, and increasingly, other applications Handheld Computer: term sometimes used interchangeably with PDA, palmtop , or pocket computer; may imply a device in between a laptop and PDA; more memory, more features
