Polydopamine (PDA) microcapsules with varied wall structures were created using mussel-inspired chemistry. The PAH-PDA variant, featuring a porous, interconnected wall, demonstrated superior performance for enzyme immobilization.

Area of Science:

  • Materials Science
  • Nanotechnology
  • Biochemistry

Background:

  • Microcapsule wall structure significantly impacts performance in various applications.
  • Mussel-inspired polydopamine (PDA) offers versatile material properties for microcapsule fabrication.

Purpose of the Study:

  • To synthesize and characterize PDA microcapsules with distinct wall architectures.
  • To evaluate the structure-property relationships of these microcapsules, particularly for enzyme immobilization.

Main Methods:

  • Template-mediated synthesis using CaCO3 microspheres (doped with PAH, PSS, or pure) as sacrificial templates.
  • Dopamine polymerization onto templates followed by CaCO3 removal using EDTA-2Na.
  • Characterization of microcapsule wall porosity, thickness, and interconnectivity.

  • Enzyme (catalase) immobilization and assessment of encapsulation efficiency, activity, stability, and leaching.

    • Main Results:

    • Three types of PDA microcapsules were produced: PAH-PDA (thick, porous, interconnected), pure-PDA (thick, less porous), and PSS-PDA (thin, dense).
    • Higher wall porosity and interconnectivity correlated with increased mass transfer coefficients.
    • PAH-PDA microcapsules exhibited enhanced catalase immobilization, including higher encapsulation efficiency, improved enzyme activity and stability, and reduced leaching compared to pure-PDA and PSS-PDA variants.

    Conclusions:

    • The hierarchical structure of PAH-PDA microcapsules, with their highly porous and interconnected walls, offers significant advantages for enzyme immobilization.
    • These findings suggest potential applications for structured PDA microcapsules in biocatalysis, biosensors, and drug delivery.
