Case Study: Lab-on-Chip Blood Cell Analysis Device

A useful BioMEMS case study is a microfluidic blood-analysis Lab-on-Chip designed to prepare, separate and detect blood components.

Working principle

1. A small blood sample is introduced through a microfluidic inlet.
2. Microchannels guide the sample under controlled laminar flow.
3. Filters or microstructures separate cells according to size, deformability or other properties.
4. Additional microfluidic regions can concentrate or mix the sample with reagents.
5. Sensors or optical detection zones measure the target cells or analytes.
6. Electronics process the signal and provide an analytical result.

Impact

• Requires only a small sample volume.
• Can reduce analysis time.
• Enables portable or point-of-care testing.
• Reduces reagent consumption.
• Integrates sample preparation and analysis.
• Can support rapid screening in resource-limited settings.

Conclusion

The integration of microfluidics, sensing and electronics demonstrates how BioMEMS can convert laboratory procedures into compact, automated diagnostic platforms.
