This study introduces a microfluidic device for high-throughput single-cell analysis. It efficiently traps cells using dielectrophoresis (DEP) and lyses them with electroporation (EP) for rapid, precise cellular studies.

Area of Science:

Biotechnology
Microfluidics
Cell Biology

Background:

Analyzing large cell populations at the single-cell level is crucial for understanding biological heterogeneity.
Existing methods often face challenges in throughput, precision, and maintaining cellular integrity during analysis.

Purpose of the Study:

To develop and validate a novel microfluidic device for efficient arraying and analysis of single cells.
To enable rapid, high-throughput manipulation and lysis of cells within a microfluidic platform.

Main Methods:

A microfluidic device featuring an array of electroactive microwells was designed.
Dielectrophoresis (DEP) was used for active cell trapping within microwells (95% efficiency in <3 minutes).
Electroporation (EP) was employed for controlled cell lysis, followed by analysis of intracellular contents.
