What are the challenges in detecting and measuring nanomaterials?
Detecting and measuring nanomaterials in biological and environmental samples is a significant challenge due to their small size and low concentration. Traditional analytical techniques often lack the sensitivity and specificity required for accurate measurement. Advanced methods such as scanning electron microscopy (SEM), transmission electron microscopy (TEM), and dynamic light scattering (DLS) are essential for characterizing nanoparticles, but these techniques can be costly and time-consuming. The development of reliable, cost-effective, and standardized detection methods is necessary to ensure the safe monitoring of nanomaterials.
