A new technique can label diverse molecules and amplify the signal to help researchers spot those that are especially rare. Called SABER (signal amplification by exchange reaction), Peng Yin’s lab at Harvard’s Wyss Institute first introduced this method last year and since have found ways to apply it to proteins, DNA and RNA.
Wearable tech requires both strength and flexibility. A new nanowire design — a boron nitride nanotube (BNNT) filled with tellurium atomic chains — holds promise for electronics triggered by light and pressure. In collaboration with Purdue University, Washington University and University of Texas at Dallas, Michigan Tech physicists created and tested the new nanowire alongside carbon nanotubes.
It can be the bain of brain drug developers: The interface between the human brain and the bloodstream, the blood-brain-barrier, is so meticulous that animal models often fail to represent it. This improved chip represents important features more accurately.
Scientists can control their branch sizes and surfaces to make them more stable and more effective catalysts. By creating branched nanoparticles from the metal ruthenium, researchers developed a way to increase the speed of catalysis while maintaining the catalyst’s stability.
The first hours of a lithium-ion battery’s life largely determine just how well it will perform. In those moments, a set of molecules self-assembles into a structure inside the battery that will affect the battery for years to come. Now scientists have witnessed the formation of the solid-electrolyte interphase at a molecular level.
Scientists at Berkeley Lab’s Molecular Foundry have designed a biocompatible polymer that has the potential to advance photothermal therapy, a technique that deploys near-infrared light to combat antibacterial-resistant infections and cancer.
