Enzyme-containing patterned porous films were created using a simple breath figure method. These biohybrid films, made from self-assembled horseradish peroxidase nanoparticles, demonstrate strong catalytic activity and solvent resistance.

Area of Science:

  • Biomaterials science
  • Nanotechnology
  • Catalysis

Background:

  • Enzyme immobilization is crucial for developing reusable and stable biocatalysts.
  • Patterned materials offer advantages in controlling biological and chemical processes.
  • Horseradish peroxidase (HRP) is a widely studied enzyme with diverse applications.

Purpose of the Study:

  • To develop a facile method for preparing patterned porous films containing enzymes.
  • To investigate the properties and catalytic activity of enzyme-based biohybrid films.
  • To assess the stability of the enzyme nanoparticles in organic solvents.

Main Methods:

  • A one-step breath figure process was employed for film preparation.
  • Self-assembly of horseradish peroxidase nanoparticles was utilized.
