Research biologists, chemists and theoreticians at the U.S. Naval Research Laboratory (NRL) are on pace to develop the next generation of functional materials that could enable the mapping of the complex neural connections in the brain. The ultimate goal is to better understand how the billions of neurons in the brain communicate with one another during normal brain function, or dysfunction, as a result of injury or disease. A full report of the research team's findings, entitled "Electric Field Modulation of Semiconductor Quantum Dot Photoluminescence: Insights Into the Design of Robust Voltage-Sensitive Cellular Imaging Probes," was published September 28, in the American Chemical Society publication, NANO Letters. An abstract of the report is available on the ACS website. Also, you can read the article on the U.S. Navy website.
