Dec 04, 2023 (Nanowerk News) For the first time, it is possible to follow, step-by-step and with atomic resolution, what happens when the enzyme DNA photolyase repairs ultraviolet light-induced DNA damage. An international team of researchers led by Academia Sinica, Taiwan, has taken snapshots of the repair process with extremely...
Placing nanoparticles in the palm of your hand
Dec 04, 2023 (Nanowerk News) Nanoparticles are super tiny―as small as one nanometer, or one billionth of a meter―and are of keen interest to materials scientists for their unique physical and chemical properties. They cannot be detected by the naked eye and require a highly specialized electron microscope to be...
Low-cost microscope projection photolithography system for high-resolution fabrication
Dec 04, 2023 (Nanowerk News) Integrated optical signal distributing, processing, and sensing networks require the miniaturization of basic optical elements, such as waveguides, splitters, gratings, and optical switches. To achieve this, fabrication approaches that allow for high-resolution manufacturing are required. Curved elements like bends and ring resonators are especially challenging...
Graphene discs generate picosecond-switchable magnetic fields
Dec 04, 2023 (Nanowerk News) Stimulated by corkscrew-shaped radiation: physicists at the University of Duisburg-Essen and their cooperating partners have discovered that tiny graphene sheets can become electromagnets under infrared radiation. The findings are published in Nature Communications ("Strong transient magnetic fields induced by THz-driven plasmons in graphene disks"). The...
Technique could help tap 2D van der Waals ferroelectrics for use in next-generation electronics
Dec 04, 2023 (Nanowerk News) The properties that make materials like semiconductors so sought after result from the way their atoms are connected, and insight into these atomic configurations can help scientists design new materials or use existing materials in new, unforeseen ways. Rice University materials scientist Yimo Han and...
State of the art in soft microrobotics materials, fabrication and actuation
Dec 04, 2023 (Nanowerk News) The concept of microrobots has evolved significantly since physicist Richard Feynman first envisioned the potential of tiny machines in the 1950s. The early prototypes of microrobots, with their rigid bodies, faced substantial challenges in navigating complex biological and industrial environments without causing damage. This led...
Breakthroughs in nanosized contrast agents and drug carriers through self-folding molecules
Dec 04, 2023 (Nanowerk News) Self-folding polymers containing gadolinium forming nanosized complexes could be the key to enhanced magnetic resonance imaging and next-generation drug delivery, as demonstrated by scientists at Tokyo Tech. Thanks to their small size, low toxicity, and good tumor accumulation and penetration, these complexes represent a leap...
