Super-Resolution Map (IMAGE) Rice University Caption This is a super-resolution map of identified individual bovine serum albumin molecules, as marked by the colored outlines. The gold nanowire, in gray and thousands of nanometers long, shows the relative size of the proteins, which occupy areas much larger than expected based on the size of their unfolded geometry. The researchers said this supports the finding that there's only space for one protein on the smaller nanoparticles studied. Credit Rice University Usage Restrictions For news release purposes only.
