Nano

Physicists have levitated nanoscale diamonds, hit them with lasers to make them flash and spun them at an incredible 1.2 billion rpm. The experiments aren’t just about creating the “world’s smallest disco” but could help the study of quantum physics.

Researchers have demonstrated a programmable nano-scale robot, made from a few strands of DNA, that's capable of grabbing other snippets of DNA, and positioning them together to manufacture new UV-welded nano-machines – including copies of itself.

AI machine learning uses so much computing power and energy that it's typically done in the cloud. But a new microtransistor, 100X more efficient than the current tech, promises to bring new levels of intelligence to mobile and wearable devices.

Physicists have combined nanotechnology, artificial intelligence and molecular biology to design a novel method that can detect Alzheimer’s disease protein markers in blood that are the tell-tale signs of early neurodegeneration.

For the estimated 800 million people worldwide with acne, a successful new treatment would have a profound impact on quality of life. Scientists hope their new treatment method, using a drug that's unique in human medicine, will be the 'magic bullet.'

Researchers have developed a new open-source program that can convert drawings or digital models into nanoscale sculptures made of DNA. In tests, the system nailed rounded objects like vases and bowls.

Researchers at the Technical University of Munich (TUM) have developed the world’s first electric nanomotors made of DNA. The self-assembling structures can be activated by an electric charge to spin a ratcheting rotor arm.

In many fields of technology, smaller is better, and machinery is now getting so tiny it’s measured in mere atoms. Researchers at the University of Erlangen–Nuremberg in Germany have now developed the world’s smallest working gear wheels.

Researchers have developed a simple new way to make material surfaces with intricate nanoscale textures, all inspired by nature. Different patterns have a range of applications, like making antimicrobial surfaces or reducing ship hull friction.

A team of researchershas advanced development of a nanochip device that can reprogram cells in the body to become new blood vessels and nerve cells. It could be used to repair brain damage resulting from a stroke or nerve damage caused by diabetes.

Researchers at Empa and EPFL have created one of the smallest motors ever made. It’s composed of just 16 atoms, and at that tiny size it seems to function right on the boundary between classical physics and the spooky quantum realm.

Antioxidants fight oxidation, which can spoil food and alcohol and harm cells in the body. Now, researchers have woven antioxidants into nanofiber mats, which release the vital compounds slowly and could be useful for food coverings or bandages.
