New poly(amino acids) (l-glutamic acid, l-tyrosine and l-lysine) containing photosensitive acryloyl, methacryloyl, and cinnamoyl groups in their side chains were synthesized from the corresponding amino acid NCAs. Their photosensitivities under UV irradiation were also investigated as to kind of functional group and the skeleton portion of the poly(amino acids). As regards the effect of the former, the sensitivities were in the order: acryloyl\simeqmethacryloyl>cinnamoyl; as regards the effect of the latter, the sensitivities were in the order: poly-glutamate>poly-lysine>poly-tyrosine.

The present invention relates to copolymers made from a polymerization mixture comprising (a) one or more polymerizable monomers, which monomers are characterized as having at least one vinylic group and not containing an amino acid residue, (b) one or more not-functionalized side chain-linked amino acids, (c) one or more functionalized side chain-linked amino acids, (d) a free radical initiator and, optionally, (e) a chain-transfer-agent. It also relates to block copolymers comprising the same monomers. The invention also encompasses silicone hydrogel contact lenses coated with or comprising the latter copolymers and block copolymers as well methods for introducing the copolymers and block copolymers into silicone hydrogel contact lenses.

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.
