What are the Challenges in Signal Monitoring at the Nanoscale?
Signal monitoring at the nanoscale presents several challenges, including:
1. Sensitivity: Achieving high sensitivity while minimizing noise and interference is critical. Nanosensors must be able to detect extremely low concentrations of analytes. 2. Specificity: Nanosensors must be highly specific to the target analyte to avoid false positives. This often requires functionalization with biorecognition elements. 3. Integration: Integrating nanosensors into larger systems or devices can be complex. Ensuring reliable and consistent performance in different environments is essential. 4. Cost and Scalability: Developing cost-effective and scalable manufacturing processes for nanosensors is necessary for widespread adoption.
