APPLICATIONS OF NANOMATERIALS ABSTRACT : Nanomaterials For Applications Must Meet Two basic Requirements, Engineering And Medical Field. It Influences Almost Every Fact Of Every Day Life Such As Engineering And Medicine. These New Technologies Are Bound to Have An Impact On the Chemicals, Energy, Electronics And Space Industries. They Will Also Have Applications In Medicine And Health, Drug, And Gene Delivery. This Article Examines the Important Facts Of Nanomaterials Research, Highlighting The Current Trends And Future Directions. KEY WORDS : Nanomaterials, Nanotechnology, Engineering And Medical Fields. INTRODUCTION: 1. Nanotechnology is defined as fabrication of devices with atomic or molecular scale precision. 2. Devices with minimum feature sizes less than 100 nanometers (nm) are considered to be products of nanotechnology. 3. A nanometer is one billionth of a meter (10-9 m) and is the unit of length that is generally most appropriate for describing the size of single molecules. 4. The first revolutionary applications of nanotechnology will be in computer science and medicine. NANOTECHNOLOGY: 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 products. The advantages of nanotechnology One of the basic principles of nanotechnology is positional control. At the macroscopic scale, the idea that we can hold parts in our hands and assemble them by properly positioning them with respect to each other goes back to prehistory: we celebrate ourselves as the tool using species. Our wisdom and our knowledge would have done us scant good without an opposable
