Purpose of the Study:

  • To develop and validate a novel device for fabricating high-quality microcapsules.
  • To assess the device's capability in producing microcapsules with specific size and surface characteristics.
  • To confirm the viability of encapsulated cells within the fabricated microcapsules.

Main Methods:

  • Utilizing a newly designed device for microcapsule fabrication.
  • Employing piglet pancreatic cells as the encapsulated cell source.
  • Characterizing microcapsule size, surface smoothness, and cell viability post-encapsulation.

Main Results:

  • The device successfully fabricated microcapsules of a preset size.
  • Microcapsules exhibited an even, smooth surface without defects.
  • No adhesion between microcapsules was observed.
  • Encapsulated piglet pancreatic cells maintained viability.

Conclusions:

  • The developed device offers a reliable method for producing uniform, high-quality microcapsules.
  • This technology is suitable for encapsulating viable cells, such as those from piglet pancreases.
  • The microcapsules are well-suited for applications requiring precise size, smooth surfaces, and cell integrity.
