Shrinking hydrogels enlarge nanofabrication options

Researchers from Carnegie Mellon University and the Chinese University of Hong Kong have developed a strategy for creating ultrahigh-resolution, complex 3D nanostructures out of various materials.

Could tiny devices made out of DNA treat cancer?

One of the most promising avenues in treating cancer is to restore our immune system's ability to recognize and attack cancerous cells. A team of University of Chicago chemists and biologists developed a tiny device that ...

MIT turns 'magic' material into versatile electronic devices

In a feat worthy of a laboratory conceived by J.K. Rowling, MIT researchers and colleagues have turned a "magic" material composed of atomically thin layers of carbon into three useful electronic devices. Normally, such devices, ...

DNA robots designed in minutes instead of days

Someday, scientists believe, tiny DNA-based robots and other nanodevices will deliver medicine inside our bodies, detect the presence of deadly pathogens, and help manufacture increasingly smaller electronics.

Cloaked DNA nanodevices survive pilot mission

It's a familiar trope in science fiction: In enemy territory, activate your cloaking device. And real-world viruses use similar tactics to make themselves invisible to the immune system. Now scientists at Harvard's Wyss Institute ...

Revisiting quantum effects in MEMS

New calculations shows that the influence of quantum effects on the operating conditions of nanodevices has, until now, been overestimated.

New method for imaging defects in magnetic nanodevices

(—A team of researchers from the NIST Center for Nanoscale Science and Technology, the Royal Institute of Technology, Stockholm, and the University of Maryland have demonstrated a microscopy method to identify ...

Nanotechnology (sometimes shortened to "nanotech") is the study of manipulating matter on an atomic and molecular scale. Generally, nanotechnology deals with developing materials, devices, or other structures possessing at least one dimension sized from 1 to 100 nanometres. Quantum mechanical effects are important at this quantum-realm scale.

Nanotechnology is very diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly, from developing new materials with dimensions on the nanoscale to investigating whether we can directly control matter on the atomic scale. Nanotechnology entails the application of fields of science as diverse as surface science, organic chemistry, molecular biology, semiconductor physics, microfabrication, etc.

There is much debate on the future implications of nanotechnology. Nanotechnology may be able to create many new materials and devices with a vast range of applications, such as in medicine, electronics, biomaterials and energy production. On the other hand, nanotechnology raises many of the same issues as any new technology, including concerns about the toxicity and environmental impact of nanomaterials, and their potential effects on global economics, as well as speculation about various doomsday scenarios. These concerns have led to a debate among advocacy groups and governments on whether special regulation of nanotechnology is warranted.
