Enzyme‐Loaded Fe3+‐Modified Polydopamine Microparticles: Bioreactor Systems for Operating Biocatalytic Cascades, Enantioselective Transformations and Sensor Applications

Advanced Functional Materials, EarlyView.
Enzyme‐loaded Fe3+‐modified polydopamine microparticles (Fe3+‐PD) act as hybrid biocatalytic frameworks demonstrating NADH peroxidase‐mimic catalytic activities, operation of biocatalytic cascades in confined media, and enantioselective oxidation of D/L‐DOPA. ABSTRACT We report on the synthesis of Fe3+‐modified porous polydopamine microparticles acting

Chamber‐Specific Decellularized Extracellular Matrices Differentially Modulate Cardiomyocyte Subtypes to Drive Engineered Heart Tissue Development and Function

Advanced Healthcare Materials, EarlyView.
Chamber‐specific decellularized extracellular matrices (ECMs) were developed, preserving native proteomic profiles of ventricular and atrial myocardium. These innate biochemical cues differentially modulate cardiomyocyte subtypes to drive engineered heart tissue development and function, highlighting the importance of incorporating regional ECM cues in

Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

Advanced Materials, EarlyView.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.
