What are the Challenges in Shear Testing of Biological Tissues?
Shear testing of biological tissues comes with several challenges:
1. Heterogeneity: Biological tissues are often heterogeneous, consisting of different cell types and extracellular matrix components, which can complicate the interpretation of results. 2. Sample Handling: Tissues can be delicate and may undergo changes during preparation, which can affect their mechanical properties. 3. Measurement Sensitivity: Accurate measurement of small deformations requires highly sensitive instruments and techniques. 4. Environmental Factors: Temperature, humidity, and other environmental factors can influence tissue properties and must be carefully controlled during testing.
