Probe Tack Measurements of Combinatorial Libraries

The video tutorial covers the generation of combinatorial libraries and measurements, focusing on adhesion research. It explains pressure-sensitive adhesives (PSAs), their properties, and applications, such as Scotch tape. The video details methods to test adhesive strength, including shear, peel, and probe tests. It describes the experimental setup using an inverted optical microscope and a precise motor assembly. The tutorial concludes with a demonstration of conducting an adhesion test, measuring forces, and evaluating PSA performance.
