Magnetic Honeycomb

Description

Honorable Mention The microscopic particles shown here are made of iron oxide, or rust, just like on a car. But these nanoparticles are tiny, 100,000 times thinner than a sheet of paper.In this image all the nanoparticles are the same size and shape and distance apart, and each magnetic particle is subjected to the attraction and repulsion forces of its neighbors. As a result, the magnetic nano-particles self-assemble (or come together) in a closely-packed honeycomb pattern. Iron oxide nanoparticles like these are already used to help people suffering from anemia, or iron deficiency. Researchers study how these magnetic nanoparticles interact with each other and with tissues in the body, which can open new avenues for nontoxic, targeted tests and treatments for cancer, Alzheimers and cardiovascular disease.Northwestern University Atomic & Nanoscale Characterization Experimental Center (NUANCE)Tools & Techniques: Transmission Electron Microscope + colored in Photoshop

Abstract

This image originally appeared as part of Northwestern's Scientific Images Contest. The contest and subsequent exhibitions are organized by Science in Society, the university's research center for science education and public engagement. Further information and opportunities to participate are available on their website. Prints and canvas editions of these Northwestern research images can also be purchased online (with the small net profit going to science education and outreach programming in the Chicago area).
