What are the Challenges in Using Targeted Contrast Agents?
Despite their advantages, there are several challenges in the use of targeted contrast agents:
Specificity and Sensitivity: Ensuring that the agents bind only to the target cells and not to similar non-target cells. Toxicity: Some contrast agents may be toxic to cells or tissues, limiting their use in live imaging. Cost: Developing and producing targeted contrast agents can be expensive, which may limit their accessibility for widespread use. Regulatory Approval: Gaining approval for new agents can be a lengthy and complex process.
