NANO TECHNOLOGY (SHAPING THE FUTURE)
ABSTRACT
ABSTRACT
A basic definition of Nanotechnology is the study manipulation and manufacture of extremely minute machines or devices. The future of technology at times becomes easier to predict. Computers will compute faster, materials will become stronger and medicine will cure more diseases .the technology that works at the nanometer scale of molecules and atoms will be a large part of this future, enabling great improvements in all the fields of human presence. A supercomputer no bigger than a human cell. A spacecraft no longer or more expensive than the family car. These are just a few promises of nanotechnology.
Within a decade, nanotechnology is expected to be the basis of $1 trillion worth of products in the United States alone and will create anywhere from 8, 00,000 to 2 million new jobs.Nanotechnology is expected to have a revolutionary impact on medicine. A variety of medical processes occur at nanometer length scales. Among the approaches for exploiting developments in nanotechnology in medicine, nanoparticles offer some unique advantages as sensing, delivery, and image enhancement agents. Several varieties of nanoparticles are available including, polymeric nanoparticles, metal nanoparticles, liposomes, micelles, quantum dots, dendrimers.
