Mar 26, 2026 Researchers have developed a new method based on laser modification, which allows metal-organic materials to be grown locally one molecule-thick layer at a time. The method enables the precise construction of films of different shapes and offers new ways to modify the properties of materials for various...

Mar 26, 2026 A new LED design uses a built-in nanoscale metasurface to emit circularly polarized light directly, eliminating bulky optics for 3D displays and AR devices. (Nanowerk News) From 3D movie screens to augmented-reality devices, many modern technologies rely on our ability to manipulate light. Doing so in a...

Mar 26, 2026 3D metastructures produce programmable structural colors for optical encryption, with a destruction mechanism that permanently erases data after readout. (Nanowerk News) Researchers at City University of Hong Kong have developed three-dimensional metastructures, tiny engineered surface elements that manipulate light through their shape rather than through dyes or...

Mar 26, 2026 Researchers developed a method to self-assemble metal-organic framework nanosheets just 3 nanometers thick at a liquid-air interface, without toxic solvents or high temperatures. (Nanowerk News) Metal-organic frameworks (MOFs) are porous structures composed of metal ions (or clusters) and organic linker molecules – much like a molecular scaffold....

Mar 26, 2026 Nanoparticles built from red blood cell membranes and loaded with a sound-sensitive dye kill liver cancer cells when triggered by ultrasound while remaining nontoxic without activation. (Nanowerk Spotlight) Red blood cell (RBC) membranes carry CD47, a protein that sends a molecular "don't eat me" signal to immune...

Mar 26, 2026 Outgassing jets may have stopped the comet's spin and restarted it in the opposite direction. (Nanowerk News) Astronomers using NASA’s Hubble Space Telescope have found evidence that the spinning of a small comet slowed and then reversed its direction of rotation, offering a dramatic example of how...

Mar 26, 2026 Spray-coated carbon flower sensors on stretchable substrates detect six biomarkers at sub-nanomolar levels and distinguish them in multi-analyte mixtures for wearable monitoring. (Nanowerk Spotlight) Electrochemical sensors that detect biological molecules generally face a trade-off. Simple carbon electrodes are cheap, stable, and easy to fabricate, but they struggle...

Mar 26, 2026 A new programmable metasurface performs dynamic beamforming and radar cross-section reduction across five frequency bands in a design 87% thinner than conventional approaches. (Nanowerk News) Researchers at Xidian University have developed a programmable metasurface that performs dynamic beamforming for communication while simultaneously reducing radar cross-section (RCS) across...

Mar 26, 2026 Researchers use field-resolved techniques to study how light interacts with nanocrystals, revealing ultrafast optical switching behavior on femtosecond timescales. (Nanowerk News) Just as an antenna interacts with radio waves, light interacts with metallic nanostructures. Therefore, understanding how a structure influences field oscillations provides valuable insights into the...

Mar 26, 2026 New carbon capture materials regenerate below 60 Celsius, low enough to use industrial waste heat, cutting the energy cost of the CO2 capture cycle. (Nanowerk News) Researchers at Chiba University have synthesized a new class of nitrogen-doped carbon materials called viciazites that can release captured carbon dioxide...
