While the benefits are significant, there are challenges and risks associated with the use of MNPs in histology: 1. Biocompatibility: Ensuring that MNPs are biocompatible and do not induce cytotoxic effects is critical. 2. Clearance and Accumulation: Understanding how these particles are cleared from the body and their potential for accumulation in tissues is essential for long-term safety. 3. Standardization: Developing standardized protocols for the use of MNPs in histology is necessary to ensure reproducibility and reliability of results.
