Area of Science:

  • Biomaterials Science
  • Polymer Chemistry
  • Emulsion Technology

Background:

  • High internal phase emulsions (HIPEs) are useful for encapsulating water-immiscible substances.
  • Conventional polyHIPEs often use non-biocompatible surfactants, limiting biological uses.
  • There is a need for biocompatible porous materials for applications like drug-eluting devices.

Purpose of the Study:

  • To develop a straightforward method for fabricating porous biomaterials using proteins.
  • To utilize proteins as both emulsifiers and structural components in polyHIPEs.
  • To explore the potential of protein-based polyHIPEs for drug encapsulation and release.

Main Methods:

  • Proteins were used as emulsifiers and building blocks for HIPE formation.
  • Essential oils were employed as the internal phase to demonstrate versatility.
  • Protein gelation was triggered by reducing agents to form a stable hydrogel.
  • Porous scaffolds were obtained by extracting essential oils or utilized for controlled release.

Main Results:

  • A novel method for creating protein-based polyHIPEs was successfully established.
  • The protein-based polyHIPEs demonstrated versatility with various essential oils.
  • The resulting materials could be processed into porous scaffolds or used for sustained release.
  • The biocompatibility of protein-based materials opens avenues for biomedical applications.

Conclusions:

  • Proteins can effectively serve as both emulsifiers and building blocks for polyHIPE fabrication.
  • This protein-based approach offers a biocompatible alternative to conventional polyHIPEs.
  • The developed method allows for the creation of tunable porous biomaterials for diverse applications.
  • Protein-based polyHIPEs show promise for drug delivery systems and antimicrobial applications.
