How smart, ultrathin nanosheets go fishing for proteins

An interdisciplinary team from Frankfurt and Jena has developed a kind of bait with which to fish protein complexes out of mixtures. Thanks to this 'bait,' the desired protein is available much faster for further examination in the electron microscope. The research team has christened this innovative layer of ultrathin molecular carbon the 'smart nanosheet.' With the help of this new development,
