Area of Science:

Biophysics
Microfluidics
Proteomics

Background:

Protein array technologies are vital in proteomics but require new high-throughput interaction analysis methods.
Existing methods for studying protein-protein and protein-compound interactions are limited in throughput.

Purpose of the Study:

To present a novel microfluidic system for forming an array of suspended lipid bilayer membranes.
To enable high-throughput analysis of protein interactions using an integrated, reusable device.

Main Methods:

A three-layer microfluidic device with integrated Ag/AgCl electrodes was designed.
Simultaneous formation of an array of lipid bilayers was achieved using an air-exposure technique.
Independent addressability of electrode sites allowed for ion channel measurements.

Main Results:

The device demonstrated simultaneous formation of lipid bilayers across 12 sites with a 50% yield.
Ion channel recordings were successfully acquired from multiple sites within the array.
The clamped design allows for device cleaning and reusability.

Conclusions:

The developed microfluidic system provides a robust platform for suspended lipid bilayer arrays.
This technology has significant potential for creating an automated platform for high-throughput interaction studies.
The reusable and cleanable nature of the device enhances its practical applicability in proteomics.
