Integration Of Semiconductor-Based Components And Functionality Into Soft Microfluidics For Cell Lysis And Other Biological Applications
SUMMARY
This technology delivers precise and scalable cellular content extraction for genomic analyses by integrating semiconductor-based piezoelectric sharp tip arrays into soft microfluidics, enabling efficient mechanical cell lysis, particularly of hard-shelled microbial cells, thereby enhancing throughput and control in single-cell genomics.
The Unmet Need: Efficient and controllable microbial cell lysis for high-throughput single-cell genomics
- Current methods for microbial cell lysis often struggle with the physical robustness of cell walls, resulting in inefficient, biased, or inconsistent sample preparation that limits the accuracy and throughput of single-cell genomic analyses. Mechanical disruption approaches frequently lack scalability and precise control, thereby impeding comprehensive microbial profiling.
- The growing demand for high-throughput and minimally biased single-cell genomic technologies in diagnostics and research is driving innovation toward microfluidics-integrated platforms that can combine precise mechanical action with scalable, automated processing within compact devices.
The Proposed Solution: Microfabricated silicon chip with piezoelectric-driven sharp tip arrays integrated into microfluidic devices for physical cell lysis
- The faculty inventor developed a microfabricated silicon chip embedding piezoelectric actuators that vibrate sharp tip arrays, physically lysing microbial cells within a soft microfluidic environment; this allows for
precise mechanical disruption of even hard-shelled cells with enhanced control and scalability compared to chemical or purely mechanical methods. Distinct from current lysing techniques, this solution integrates semiconductor fabrication technology with microfluidics to facilitate consistent cell perforation and content release, supporting high-throughput workflows for genomic analyses.
- The system targets microbial cells with diverse shell robustness and is engineered for applications demanding controlled and repeatable lysis mechanisms.
