![]() ![]() An obvious route when thinking about the very small is to shrink the size and cost of computers, and speed their operation phenomenally. As transistor sizes decrease to nanometer regime, we are approaching the point where nano-lithography will achieve the required resolution for creating these nanometer-sized devices. The fabrication of smaller and faster transistors has long been a driving force for the computer industry. ![]() Substantially smaller size, lower weight, more modest power requirements, greater sensitivity, and better specificity are just a few of the improvements we will see in sensor design. Nanotechnology enables us to create functional materials, devices, and systems by controlling matters at the atomic and molecular scales, and to exploit novel properties and phenomena. ![]() In the last couple of years, the term “Nanotechnology” has been inflated and has almost become synonymous for things that are innovative and highly promising. With our ever increasing knowledge of nanoscience and the ability to engineer new products and services, it would not be far before the entire history can be compressed inside our pockets or the system extended by specially designed molecules that mimic the living systems. Current nanotechnology is building devices of microscopic or even molecular size, which will potentially be benefiting medicine, environmental protection, energy, and space exploration. When the dimensions of a material become very small, its physical and chemical properties can become very different from those of the same material in bulk form. ![]() Many scientists consider nanotechnology as the next logical step in science, integrating engineering with biology, chemistry, medicine, and physics. ![]()
