D.N.A computers

Even as you read this article, computer chip manufacturers are furiously racing to make the next microprocessor that will topple speed records. Sooner or later, though, this competition is bound to hit a wall. Microprocessors made of silicon will eventually reach their limits of speed and miniaturization. Chip makers need a new material to produce faster computing speeds.

You won't believe where scientists have found the new material they need to build the next generation of microprocessors. Millions of natural supercomputers exist inside living organisms, including your body. DNA (deoxyribonucleic acid) molecules, the material our genes are made of, have the potential to perform calculations many times faster than the world's most powerful human-built computers. DNA might one day be integrated into a computer chip to create a so-called biochip that will push computers even faster. DNA molecules have already been harnessed to perform complex mathematical problems.

While still in their infancy, DNA computers will be capable of storing billions of times more data than your personal computer. In this article, you'll learn how scientists are using genetic material to create nano-computers that might take the place of silicon-based computers in the next decade.

NANOTECHNOLOGY

Nanotechnology, shortened to "nanotech", is the study of the control of matter on an atomic and molecular scale. Generally nanotechnology deals with structures of the size 100 nanometers or smaller, and involves developing materials or devices within that size. Nanotechnology is very diverse, ranging from novel extensions of conventional device physics, to completely new approaches based upon molecular self-assembly, to developing new materials with dimensions on the nanoscale, even to speculation on whether we can directly control matter on the atomic scale.
Scientists and engineers are collaborating across disciplines to develop and network miniaturized intelligent nanosensors that can rapidly and remotely detect change in their surroundings. These sensors have a wide range of potential applications: environmental, medical, military and transportation. This workshop will focus on revealing the chemistry and physics behind the creation and application of these sensors. Series: "Molecules for the Media"

The truth about Nanotechnology

A concise introduction to what NT is, what it can't do yet and what we should be aware of Nanotechnology marks the merger of different technologies in structures smaller than 100 nm. While it could yield some powerful applications for sustainability, medicine and electronics, some hazards begin to appear that have to be addressed urgently
