A series of gradually strengthened DNA supramolecular hydrogels have been constructed for simulating gradual stiffing of extracellular matrix. In the initial states, the supramolecular hydrogels possess dynamic properties, which endow them with shear-thinning, self-healing, and injectability. With subsequent slow covalent crosslinking, the mechanical...

Green bio-based PUTA/Fe composite, responsive to NIR light, is successfully prepared by introducing Fe3+ into PUTA matrix. Its shape memory is due to PEG crystallization; while, NIR response is from Fe3+'s photo-thermal conversion. With Fe3+ content increase, PUTA/Fe's shape recovery speed improves, time reducing to 40 s. High TA content PUTA/Fe exhibits...

This study explores the formation of discrete pancake-shaped superlattices (DPSs) through air–liquid interface self-assembly facilitated by block copolymers. By adjusting experimental parameters, such as block copolymer concentration and molecular architecture, unique DPS morphologies are achieved. The findings highlight the crucial role of polymer...

Abstract Protein-polymer conjugates and polymeric nanomaterials hold great promise in many applications including biomaterials, medicine or nanoelectronics. In this work, we present the first PISA (polymerization-induced self-assembly) approach performed in aqueous medium enabling protein-polymer conjugates and nanoparticles entirely composed of amino...

N-carboxyanhydride ring-opening polymerization-induced self-assembly (NCA ROPISA) offers a convenient route for generating poly(amino acid)-based nanoparticles in a single step. Herein, this work reports the synthesis of polysarcosine-poly(amino acid) containing nanoparticles produced using this method. Abstract N-carboxyanhydride ring-opening...

Natural medicine is appropriate for treatment of chronic disease due to less side effects. In this work, dissolving microneedles patches are fabricated using baicalin nanoparticles for photothermal therapy of psoriasis. The microneedles patches exhibit excellent radical scavenging, anti-inflammatory effects, and near-infrared region II laser response,...
