Abstract
The present disclosure relates to the delivery of multiple copies of a payload molecule such as an active agent or a chelating agent capable of capturing an active agent, using as a carrier for their delivery a biocompatible copolymer comprising side chain-linked amino acids functionalized at their alpha-amino group by a reactive azide moiety by means of which the payload molecules are coupled to the copolymer. The copolymer is typically further functionalized to contain a single copy of a cell type- or tissue type-specific targeting moiety.
