Area of Science:

  • Biomaterials Science
  • Nanotechnology
  • Drug Delivery Systems

Background:

  • Therapeutic protein delivery requires materials that enhance stability and prolong half-life.
  • Biocompatibility and biodegradability are crucial for safe and effective delivery systems.

Purpose of the Study:

  • To develop novel cyclodextrin-based metal-organic frameworks (CD-MOFs) for encapsulating and delivering therapeutic proteins.
  • To investigate the controlled release profiles and retained activity of proteins delivered via CD-MOFs.

Main Methods:

  • Enzymes and immunoproteins were encapsulated within potassium-based CD-MOFs.
  • Protein release kinetics were modulated by altering the solubility of the cyclodextrin linker.
  • Protein activity post-release was assessed using catalytic and in vitro assays.

Main Results:

  • Successful encapsulation of enzymes and immunoproteins within CD-MOFs was achieved.
  • Controlled release of proteins was demonstrated, tunable via linker solubility.
  • Proteins retained significant activity after release from the CD-MOF matrix.

Conclusions:

  • Cyclodextrin metal-organic framework-based protein biocomposites represent a promising platform for therapeutic protein delivery.
  • These materials offer enhanced stability, controlled release, and preserved protein functionality.
