Purpose of the Study:
- To present a simple and rapid technique for cell loading, culturing, and phenotypic study in microfluidic devices.
- To demonstrate high-throughput and long-term cell monitoring with minimal shear force.
Main Methods:
- Utilized polydimethylsiloxane (PDMS) microfluidic devices with patterned triangular cavities.
- Employed degassing-induced aspiration for rapid cell loading (within 1 minute).
- Investigated phenotypic variation of yeast gene expression in response to copper ion concentration.
Main Results:
- Achieved controlled single-cell loading into micro-cavities.
- Demonstrated the capability for high-throughput and long-term cell monitoring.
- Observed phenotypic variations in yeast gene expression correlated with copper ion levels.
Conclusions:
