Labels are essential for several reasons: 1. Tracking and Imaging: Labels help in the visualization of nanomaterials using advanced techniques like fluorescence microscopy and electron microscopy. 2. Biocompatibility and Safety: They enable the assessment of the biocompatibility and toxicity of nanomaterials, ensuring they are safe for medical and environmental applications. 3. Functionalization: Labels can be functionalized to interact specifically with certain molecules or cells, enhancing the precision of targeted drug delivery and diagnostic imaging. 4. Quality Control: In manufacturing, labels ensure the consistency and reliability of nanoscale products.
