Spiderweb as inspiration for creating of one of the world’s most precise microchip sensors

Posted by in categories: cosmology, internet, nanotechnology, quantum physics, robotics/AI

A team of researchers from TU Delft managed to design one of the world’s most precise microchip sensors. The device can function at room temperature—a ‘holy grail’ for quantum technologies and sensing. Combining nanotechnology and machine learning inspired by nature’s spiderwebs, they were able to make a nanomechanical sensor vibrate in extreme isolation from everyday noise. This breakthrough, published in the Advanced Materials Rising Stars Issue, has implications for the study of gravity and dark matter as well as the fields of quantum internet, navigation and sensing.

One of the biggest challenges for studying vibrating objects at the smallest scale, like those used in sensors or quantum hardware, is how to keep ambient thermal noise from interacting with their fragile states. Quantum hardware for example is usually kept at near absolute zero (−273.15°C) temperatures, and refrigerators cost half a million euros apiece. Researchers from TU Delft created a web-shaped microchip sensor that resonates extremely well in isolation from room temperature noise. Among other applications, their discovery will make building quantum devices much more affordable.

The thinnest CD-RW: Atomic-scale data storage possible

Posted by in categories: computing, encryption, nanotechnology

Using a focused laser beam, scientists can manipulate properties of nanomaterials, thus ‘writing’ information onto monolayer materials. By this means, the thinnest light disk at atomic level was demonstrated.

The bottleneck in atomic-scale area may be broken by a simple technique, thanks to recent innovative studies conducted by scientists from Nanjing Normal University (NJNU) and Southeast University (SEU).

Through a simple, efficient and low-cost technique involving the focused laser and ozone treatment, the NJNU and SEU research teams, leading by Prof. Hongwei Liu, Prof. Junpeng Lu and Prof. Zhenhua Ni demonstrated that the photoluminescence (PL) emission of WS2 monolayers can be controlled and modified, and consequently, it works as the thinnest light disk with rewritable data storage and encryption capability.

Cellular Computing: “Logic Gate” Paves Way for Nanoscale Computers To Treat Cancer and Other Diseases

Posted by in categories: biotech/medical, computing, health, nanotechnology

The creation of nanoscale computers for use in precision health care has long been a dream of many scientists and health care providers. Now, for the first time, researchers at Penn State have produced a nanocomputing agent that can control the function of a particular protein that is involved in cell movement and cancer metastasis. The research paves the way for the construction of complex nanoscale computers for the prevention and treatment of cancer and other diseases.

Nikolay Dokholyan, G. Thomas Passananti Professor, Penn State College of Medicine, and his colleagues — including Yashavantha Vishweshwaraiah, postdoctoral scholar in pharmacology, Penn State — created a transistor-like ‘logic gate,’ which is a type of computational operation in which multiple inputs control an output.

“Our logic gate is just the beginning of what you could call cellular computing,” he said, “but it is a major milestone because it demonstrates the ability to embed conditional operations in a protein and control its function, said Dokholyan. ” It will allow us to gain a deeper understanding of human biology and disease and introduces possibilities for the development of precision therapeutics.”

AI Can Now Model the Molecular Machines That Govern All Life

Posted by in categories: biotech/medical, life extension, nanotechnology, robotics/AI

This month, the UW team upped their game.

Tapping into both AlphaFold and RoseTTAFold, they tweaked the programs to predict which proteins are likely to tag-team and sketched up the resulting complexes into a 3D models.

Using AI, the team predicted hundreds of complexes—many of which are entirely new—that regulate DNA repair, govern the cell’s digestive system, and perform other critical biological functions. These under-the-hood insights could impact the next generation of DNA editors and spur new treatments for neurodegenerative disorders or anti-aging therapies.

Competing quantum interactions enable single molecules to stand up

Posted by in categories: computing, nanotechnology, quantum physics

Nanoscale machinery has many uses, including drug delivery, single-atom transistor technology, or memory storage. However, the machinery must be assembled at the nanoscale, which is a considerable challenge for researchers.

For nanotechnology engineers the ultimate goal is to be able to assemble functional machinery part-by-part at the nanoscale. In the macroscopic world, we can simply grab items to assemble them. It is not impossible to “grab” single anymore, but their quantum nature makes their response to manipulation unpredictable, limiting the ability to assemble molecules one by one. This prospect is now a step closer to reality, thanks to an international effort led by the Research Centre Jülich of the Helmholtz society in Germany, including researchers from the Department of Chemistry at the University of Warwick.

In the paper, “The stabilization potential of a standing molecule,” published today, 10 November 2021 in the journal Science Advances, an international team of researchers has been able to reveal the generic stabilization mechanism of a single standing molecule, which can be used in the rational and of three-dimensional at surfaces.

“Whispering Gallery” Microresonator Can Measure Individual Nanoparticles

Posted by in categories: biotech/medical, health, nanotechnology

Forget all the nanotechnology devoted to fighting cancer, and just consider that nanoparticles have invaded makeup, anti-odor socks, sunscreen, plastic beer bottles and home pregnancy tests. Now scientists have developed a way to assess the health and environmental impact of such nanoparticles: a tiny microresonator that can detect and measure individual particles smaller than a single virus.

The microresonator is a lab-on-a-chip that harnesses the “whispering gallery” concept that’s displayed by buildings such as St. Paul’s Cathedral in London. The cathedral’s domed gallery can carry whispers easily across to the other side, but normal-volume voices end up garbled after bouncing around the dome multiple times.

Similarly, microresonators can bounce laser light many times around a circular “waveguide,” such as a glass ring. A laser frequency must perfectly fit the circumference of a ring to achieve this whispering-gallery mode.
