From designing new biomaterials to novel photonic devices, new materials built through a process called bottom-up nanofabrication, or self-assembly, are opening up pathways to new technologies with properties tuned at the nanoscale. However, to fully unlock the potential of these new materials, researchers need to "see" into their tiny creations so that they can control the design and fabrication in order to enable the material's desired properties.
This has been a complex challenge that researchers from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and Columbia University have overcome for the first time, imaging the inside of a novel material self-assembled from nanoparticles with seven nanometer resolution, about 1/100,000 of the width of a human hair. In a new paper published on April 7, 2022, in Science, the researchers showcase the power of their new high-resolution X-ray imaging technique to reveal the inner structure of the nanomaterial.
