Nov 25, 2022 (Nanowerk News) A research team, led by Prof. Xiaoyong Tian in the State Key Laboratory for Manufacturing Systems Engineering at Xi’an Jiaotong University, has successfully manufactured a thermo-tunable broadband metamaterial (T-TBM) by 3D printing. The electromagnetic (EM) response of the T-TBM can be adjusted by controlling the...
Safer touch with antiviral coatings
Nov 25, 2022 (Nanowerk News) Antiviral coatings based on nanomaterials could help reduce the risk of transmission of infectious diseases, according to a review in the International Journal of Surface Science and Engineering ("Recent development of antiviral nano-coatings for COVID-19 management"). The authors reviewed the state-of-the-art in the context of...
Protein scissors activate defense function
Nov 25, 2022 (Nanowerk News) For several years now, the CRISPR/Cas9 gene scissors have been causing a sensation in science and medicine. This new tool of molecular biology has its origins in an ancient bacterial immune system. It protects bacteria from attack by so-called phages, i. e. viruses that infect...
Astronomers observe intra-group light – the elusive glow between distant galaxies
Nov 24, 2022 (Nanowerk News) An international team of astronomers have turned a new technique onto the faint light between galaxies – known as ‘intra-group light’ – to characterise the stars that dwell there. Lead author of the study published in MNRAS ("Galaxy And Mass Assembly (GAMA): extended intragroup light...
New CRISPR-based tool inserts large DNA sequences at desired sites in cells
Nov 24, 2022 (Nanowerk News) Building on the CRISPR gene-editing system, MIT researchers have designed a new tool that can snip out faulty genes and replace them with new ones, in a safer and more efficient way. Using this system, the researchers showed that they could deliver genes as long...
A sweet new way to print microchip patterns on curvy surfaces
Nov 24, 2022 (Nanowerk News) NIST scientist Gary Zabow had never intended to use candy in his lab. It was only as a last resort that he had even tried burying microscopic magnetic dots in hardened chunks of sugar — hard candy, basically — and sending these sweet packages to...
