Several challenges exist in material analysis at the nanoscale:
1. Sample Preparation: Preparing samples without altering their native state can be difficult. 2. Resolution Limits: Even advanced microscopy techniques have resolution limits that can sometimes impede detailed analysis. 3. Interpretation of Data: The data obtained can be complex and requires expert interpretation. 4. Reproducibility: Achieving reproducible results can be challenging due to the sensitivity of nanoscale measurements.
