Methods in Melanin Research [PDF]

open access: yes, 2011
Despite intense research efforts, melanins can be still regarded as the most enigmatic pigments/biopolymers found in Nature. This state of affairs is due to the adverse physicochemical properties; the instability to acids, alkali, oxidizing agents and UV

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

open access: yesAdvanced 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
