Pros, cons & Future potential
Custom-designed labs-on-chips can be fabricated (prototyped, or produced in small series), potentially including photonics structures (e.g. waveguides, lenses, ...) to allow for optical read-out integration. In addition, the produced optofluidic devices can be enhanced with 3D nanoprinting to produce custom scaffolds (e.g. for cell growth). In terms of materials, thermoplastic polymers (PMMA, PC, COC) or glass can be used.
Sealing of microfluidic channels is sometimes challenging. Depending on the material used, several approaches are possible (laser welding, thermal bonding, chemical bonding,...).
Our fabrication technologies are very flexible and allow a large design freedom.
The fabrication technologies are also used in other areas, such as high-end free-form optics for imaging or non-imaging applications.
