Again, CA is only an indirect proof of a successful surface modification since there are many factors that contribute to a change in CA. Many other surface characterization techniques must be combined to obtain a full picture of the surface properties of polyurethane biomaterials. 2 Wilhelmy plate The Wilhelmy plate method is named after the German chemist Ludwig Wilhelmy. It is an indirect method for CA measurement that can be applied to samples in plate, rod, or fiber shape. 7. The sample is attached to the arm of a precision balance.

These small molecule antimicrobials showed good antimicrobial activity in minimum inhibition concentration (MIC) tests.
The integrity of radiolabeled protein is checked via gel electrophoresis for MW weight comparison before and after radiolabeling. The radiolabeled protein is then mixed with unlabeled protein at a certain dilution factor. Afterward, polymer samples are incubated with such mixed protein solution. After gently washing off loosely adsorbed protein, radioactivity is counted by a γ-counter and then converted to radiolabeled protein mass. The final protein adsorption is calculated by multiplying radiolabeled protein mass with dilution factor (if radiolabeled protein is diluted 10 times with unlabeled protein, the actual protein adsorption is 10 times the radiolabeled protein mass data from the γ-counter).
