What Are Some Limitations of SEM in Cancer Research?
Despite its advantages, SEM has some limitations:
Sample Preparation: Samples often require extensive preparation, including dehydration and coating with conductive materials, which can alter their natural state. Limited Penetration Depth: SEM primarily examines surface features and has limited capability to visualize internal structures of thick samples. Cost and Accessibility: SEM equipment is expensive and requires specialized facilities and trained personnel, making it less accessible for some research settings.
