Three‐dimensional (3D) orderedarrays of human immunoglobulin G (IgG) were fabricated using well‐defined full‐length antibody–polymerconjugates (APCs). The conjugates were prepared through a two‐step sequential click approach with a combination of oxime ligation and strain promoted alkyne–azide cycloaddition. They were able to self‐assemble into lamellar nanostructures with alternating IgG and po

polymerization, a new strategy for facilely producing robust nanoporous membranes with controlled incorporation of functional groups onto nanopores is developed. As exemplified by preparing nanoporous polypyrrole decorated with amino acids, this strategy exhibits a high degree of freedom for tailoring the surface functionality in the created pores.

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.

Described herein are block copolymer conjugates that form double-network hydrogels under appropriate conditions. The conjugates comprise a block of polymer end-group, a block of self-associating peptide or protein, and flexible linkers between the two. Hydrogels comprising the conjugates have the mechanical properties, including elastic modulus and fracture toughness, required for load-bearing applications, while maintaining desirable shear-thinning properties, for example, for injectability.
