11. **Potential for Artifacts in Imaging**
While cryo-SEM minimizes distortion, artifacts can still occur, such as:- Ice crystal formation during freezing
- Charge buildup on non-conductive samples
- Shadowing effects from uneven surfaces
Users must be trained to recognize and mitigate these issues.
12. **Limited Portability**
The system is not designed for field use or portable applications. It must remain in a controlled laboratory environment, limiting its utility for on-site or remote research.
