Abstract
Dynamic and reversible assembly of molecules is ubiquitous in the hierarchical superstructures of living systems and plays a key role in cellular functions. In article number 2004042 by Samuel I. Stupp and co‐workers, host ‐guest interactions between b‐cyclodextrin and adamantane‐functionalized peptide amphiphiles led to analogous superstructure formation among nanofibers. The cover displays this hierarchical superstructure formation of fluorescently labelled peptide amphiphile nanofibers captured by confocal microscopy.
