Area of Science:

Biochemistry
Microfluidics
Analytical Chemistry

Background:

Microdroplets are valuable for high-throughput biochemical analysis, typically using flow-through systems.
Flow-through systems present challenges in dynamically characterizing time-dependent reaction kinetics.
Existing methods often require complex setups for dynamic microdroplet analysis.

Purpose of the Study:

To present a practical and affordable method for creating and analyzing static microdroplet arrays.
To enable high-throughput characterization of biochemical targets and dynamic processes.
To offer an inexpensive alternative to existing microdroplet analysis techniques.

Main Methods:

Generated discrete aqueous microdroplets in oil using an air-spray gun.
Imaged microdroplets using automated microscopy.
Characterized microdroplets via automated image processing to determine location, area, and fluorescence intensity.

Main Results:

Successfully produced and characterized over 0.7 million static microdroplets with an average volume of 300 fL.
Achieved a high population density of 1.5*10^5 microdroplets/cm^2.
Demonstrated microdroplet fluorescence intensity dependence on volume and characterized enzyme kinetics of beta-galactosidase.

Conclusions:

The developed air-spray method provides an inexpensive and effective platform for high-throughput biochemical analysis.
Static microdroplet arrays allow for rapid characterization of dynamic biochemical processes, including enzyme kinetics.
This approach offers a practical alternative for researchers needing to analyze large numbers of microdroplets efficiently.
