Abstract

The disclosure relates to an amphiphilic block copolymer comprising a first block consisting of a polymeric hydrophilic domain, wherein the polymeric hydrophilic domain consists of a polyglycerol; an optional second block consisting of a hydrophobic domain and a first linker domain, wherein the second block is covalently bound to the first block via the first linker domain, an optional third block consisting of a catechol domain and a second linker domain, wherein the third block is covalently bound to the first block via the second linker domain; and a fourth block consisting of a crosslinking domain and a third linker domain, wherein the fourth block is covalently bound to the first block via the third linker domain, wherein the crosslinking domain comprises a reactive residue enabling a crosslinking between individual molecules of the amphiphilic block copolymer.
