From “nano” to “super”: Peptide conjugates that consist of cobalt-binding peptides terminated with tails of biphenyl units were used to direct the synthesis and assembly of hollow spherical superstructures of CoPt nanoparticles (see picture). These magnetically separable superstructures exhibit electrocatalytic activity for methanol oxidation.
