Controlling Drug Release From Supramolecular Polymer Surfaces by a Click‐To‐Release Reaction

open access: yesJournal of Polymer Science, EarlyView.
We present a strategy combining reactive supramolecular additives with a covalent click‐to‐release reaction for localized drug delivery. A trans‐cyclooctene additive releases a cytotoxic drug upon tetrazine administration. Fluorescent monitoring confirms release, and cytotoxic tests show effective cancer cell death.
