Area of Science:

• Biotechnology
• Microfluidics
• Materials Science

Background:

• Micro Physiological Systems (MPS), or organ-on-a-chip technology, are advanced microfluidic devices for cultivating cells and tissues.
• MPS offer a potential replacement for animal testing by enabling the study of tissue interactions.
• Current manufacturing methods for MPS can be slow and lack flexibility.

Purpose of the Study:

• To develop a universal micromachining platform for fast and flexible manufacturing of MPS.
• To integrate key technologies like laser micro cutting, structuring, 3D printing, and optical inspection.
• To enable the creation of functionalized surfaces for improved cell adhesion and product protection.

Main Methods:

• Development of a universal micromachining platform with multi-axis capabilities.
• Integration of laser micro cutting and micro-structuring of polymer foils (polycarbonate).
• Incorporation of 3D printing for fluid-tight cell culture reservoirs and Direct Laser Interference Patterning (DLIP) for surface functionalization.

Main Results:

• Successful demonstration of laser micro cutting and micro-structuring of polycarbonate foils for MPS applications.
• Establishment of technologies for generating periodical line-like structures using DLIP.
• Successful 3D printing of fluid-tight cell culture reservoirs directly onto microfluidics.

Conclusions:

• The developed universal micromachining platform enables efficient and versatile production of Micro Physiological Systems.
• The integrated technologies facilitate the creation of complex MPS with tailored surface properties.
• This platform advances the development of organ-on-a-chip devices for research and potential replacement of animal testing.
