The advantageous biological properties of polysaccharides and precise stimuli-responsiveness of elastin-like polypeptides (ELPs) are of great interest for the design of polysaccharide and polypeptide-based amphiphilic block copolymers for biomedical applications. Herein, we report the synthesis and characterization of a series of polysaccharide-block-ELP copolymers, containing two biocompatible and biodegradable blocks coupled via copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC). The resulting bioconjugates are capable of self-assembling into well-defined nanoparticles in aqueous solution upon raising the solution temperature above a specific transition temperature (Tt) – a characteristic of the ELP moiety. To the best of our knowledge, this is the first study where polysaccharides were combined with a stimuli-responsive ELP for the preparation of thermo-sensitive self-assemblies, providing insight into novel pathways for designing bioinspired stimuli-responsive self-assemblies for biomedical applications.
