Novel coupled nanopore platform offers greater precision for detecting molecules
Sep 12, 2024 (Nanowerk News) "As complex living systems, we likely have trillions upon trillions of tiny nanoscopic holes in our cells that facilitate and regulate the crucial processes that keep us alive and make up who are,” says Marija Drndić, a physicist at the University of Pennsylvania who develops...
Printing 3D photonic crystals that completely block light
Sep 12, 2024 (Nanowerk News) Photonic crystals are materials with repeating internal structures that interact with light in unique ways. We can find natural examples in opals and the vibrant coloured shells of some insects. Even though these crystals are made of transparent materials, they exhibit a "photonic bandgap" that...
