Detecting channel clogging is crucial for maintaining the functionality of nanodevices. Common methods include:
1. Optical Microscopy: High-resolution microscopes can visualize blockages at the nanoscale. 2. Electrical Measurements: Monitoring changes in electrical resistance or capacitance can indicate clogging. 3. Fluorescent Tagging: Using fluorescent markers can help in visualizing the flow of materials and identifying blockages. 4. Pressure Monitoring: Variations in pressure across the channel can signify the presence of an obstruction.
