    A facile method for engineering a freestanding biomimetic cardiac patch using biodegradable poly(lactic-co-glycolic acid) (PLGA) and stem cell-derived cardiomyocytes is presented. The biomimetic cardiac patch fabricated with microgrooved PLGA film recapitulates the anisotropic electrophysiological feature of native cardiac tissue and is believed to be applicable in the treatment of myocardial infarction.

    Elastin-like polypeptides (ELPs) are biocompatible, temperature responsive and can be made with high sequence control. This makes ELP-based materials very interesting for their use towards nanomedicine applications. Many ELP-based systems that show self-assembly into nanoparticles have been developed. This review will give an overview of the ELP-based block copolymers capable of nanoparticle formation and their design parameters.

    We show that the characteristics of aqueous two-phase systems can be exploited in combination with protein self-assembly for controlling aggregation and structuring of fibrillar proteins into 3D core–shell microgels.

  4. A Cationic Poly(2-oxazoline) with High In Vitro Transfection Efficiency Identified by a Library Approach

    An 18-membered library of cationic poly(2-oxazoline)-based copolymers has been prepared. The influence of different polymer parameters, namely the polymer side chain hydrophobicity and the type and content of amino groups, on the pDNA condensation, the transfection efficiency, the cytotoxicity, and cellular membrane interaction as well as the size, charge, and stability of the polyplexes was studied and first structure–property relationships elucidated.

  5. Protein Compatibility of Selected Cross-linking Reactions for Hydrogels

    Despite years of research, finding cross-linking reactions for hydrogels that are compatible with incorporated proteins is still challenging. The authors, therefore, investigate side reactions between a model protein and methoxypolyethylene glycol functionalized with maleimide, vinyl sulfone, acrylamide, thiol, and furyl moieties. The extent of protein modification was found to depend on the cross-linking agent and the pH during incubation.
