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

Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems

Advanced Functional Materials, EarlyView.
Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...
