This work demonstrates a design strategy to optimize antimicrobial peptides with an ideal balance of minimal cytotoxicity, enhanced stability, potent cell penetration and effective antimicrobial activity, which hold great promise for the treatment of intracellular microbial infections and potentially systemic anti-infective therapy.

We report here a facile approach to prepare filamentous supramolecular peptide-drug conjugates with precise drug/carrier stoichiometry, nearly 100% loading efficiency and exceptional anti-cancer drug efficacy for chemotherapy.

In this work, we will demonstrate a simple yet powerful strategy to assemble single-chain cationic peptides into macromolecular filamentous nanostructures with dramatically improved membrane activity, stability and transfection efficiency.
