1. What are the main benefits of glass microfluidic devices generated with FEMTOPRINT’s micromanufacturing technology in life sciences?
Glass ensures biocompatibility, chemical inertness, and optical clarity for accurate analytical results.
2. Why is glass preferred over PDMS or COC for lab-on-chip systems?
Glass offers higher chemical resistance, no leaching, no swelling, no autofluorescence, no thermal deformation, and is ideal for enhanced optical detection.
3. What microchannel sizes can be fabricated with FEMTOPRINT’s platfform?
Channels down to 30–50 µm width with high aspect ratios are achievable through FEMTOPRINT’s femtosecond laser etching.
4. Can glass microfluidic chips handle high-pressure flows?
Yes, via proper bondeding glass chips can withstand several bars of pressure thus providing hermetic sealing.
5. How are bioassays improved by glass microfluidics?
Smooth surfaces and chemical stability reduce contamination and enhance assay reproducibility.
6. Is glass suitable for single-cell or organ-on-chip systems?
Yes, its chemical inertness and optical access make it ideal for live cell observation and micro-environments.
7. Which bonding methods are best for glass microfluidic chips?
Thermal fusion and laser bonding provide strong, leak-free seals compatible with biological fluids.
8. Is it possible to bond glass with other materials?
Yes, it is possible to bond glass with other materials such as silicon.al fusion and laser bonding provide strong, leak-free seals compatible with biological fluids.
9. What the level of geometrical freedom I can achieve with FEMTOPRINT’s micromanufacturing?
Overlapping channels, buried optics, or complex manifolds are possible without alignment issues
10. Can glass microfluidic chips be reused?
Via proper cleaning and sterilization, glass chips can be reused multiple times without degradation which is one of the main advantages of fabricating chips with glass .
11. What are the optical advantages of glass chips generated with the FEMTOPRINT’s platform in diagnostics?
High transparency, low autofluorescence, embedding of optical or photonic miniaturized components, direct integration with microscopy and spectroscopy and high productivity processing.
12. What glass materials are typically used?
Fused silica and borosilicate glass are the preferred choice due to their purity and process stability.
13. How fast is the turnaround time?
FEMTOPRINT’s maskless micromanufacturing allows for the rapid creation of initial samples (generally under 5 weeks) and fast response in case of design changes.
14. Will flow remain laminar and predictable?
Glass’ rigidity ensures geometry constancy even at high pressure. Sub-micron precision and smooth channel walls guarantee reproducible laminar regimes.
15. What is the level of reproducibility of FEMTOPRINT’s chips?
Our platform guarantees an elevated degree of reproducibility and scalability to industrial scale production.
