  • Drug Delivery Systems

Background:

  • Developing advanced hydrogel materials is crucial for effective protein encapsulation and controlled release.
  • Trigger-responsive polymers offer unique advantages for dynamic drug delivery applications.

Purpose of the Study:

  • To synthesize novel water-soluble, acrylate-terminated poly(β-amino esters) with built-in trigger-responsive domains.
  • To utilize these polymers as precursors for creating photo-cross-linked, trigger-responsive hydrogels.
  • To demonstrate the utility of these hydrogels for protein encapsulation and triggered release.

Main Methods:

  • Synthesis of poly(β-amino esters) via Michael addition of diacrylates and primary amines.
  • Photoinitiated cross-linking reactions to form hydrogel networks.
  • Protein encapsulation within the hydrogel matrix.
  • Evaluation of protein release kinetics upon external triggering.

Main Results:

  • Successful synthesis of water-soluble poly(β-amino esters) with trigger-responsive properties.
  • Formation of stable, photo-cross-linked hydrogels capable of protein encapsulation.
  • Demonstration of rapid protein release from the hydrogels in response to external triggers.

Conclusions:

  • Acrylate-terminated poly(β-amino esters) are effective precursors for trigger-responsive hydrogels.
  • These hydrogels show significant potential for applications in protein delivery and controlled release systems.
