In Situ Construction of Functional Assemblies in Living Cells for Cancer Therapy

Peptide-based materials hold great promise for various biomedical applications and have drawn increasing attention over the past five years. Despite the progress in fabrication and handling peptide materials in vitro, manipulating assemblies of peptides in living cells (or animals) is still in its infancy. In this contributing review, recent work is summarized using endogenous triggers to construct functional assemblies of peptides in vivo. After introducing the triggers for inducing peptide assemblies, the recent progress is highlighted of the in situ construction of assemblies for biomedical applications with emphasis on cancer therapy. Finally, a brief perspective is provided to discuss the future promises and challenges of this emerging area of supramolecular chemistry.
