High-Throughput Screening Test for Adhesion in Soft Materials Using Centrifugation.

Area of Science:

• Materials Science
• Mechanical Engineering
• Chemical Engineering

Background:

• High-throughput screening of mechanical properties is crucial for materials discovery and predictive modeling.
• Current characterization methods lack the throughput to meet the demand for large materials property datasets.
• Existing high-throughput assays often require specialized or expensive equipment.

Purpose of the Study:

• To develop a novel, high-throughput colorimetric adhesion screening method.
• To enable rapid characterization of adhesive materials using common laboratory equipment.
• To address the unmet need for large-scale materials property data.

Main Methods:

• Utilized a common laboratory centrifuge to apply homogeneous mechanical detachment forces.
• Employed multiwell plates and microparticles for parallelized adhesion testing.
• Developed a high-throughput sample deposition technique for uniform film preparation.

Main Results:

• Achieved excellent agreement between the developed method and the standard probe tack adhesion test.
• Demonstrated method consistency and reliability across multiple formulations within a single multiwell plate.
• Achieved a throughput of up to 10^3 samples per run, limited only by plate capacity.

Conclusions:

• The developed colorimetric adhesion screening method is simple, low-cost, and offers a large dynamic range.
• This high-throughput technique significantly enhances the capacity for adhesive material characterization.
• The method has the potential to revolutionize adhesive material discovery and property prediction.
