In nanotechnology, understanding the distribution of nanoparticle properties is crucial for various applications, including drug delivery, material science, and environmental monitoring. KDE helps in visualizing and analyzing the data obtained from various nanocharacterization techniques like scanning electron microscopy (SEM), transmission electron microscopy (TEM), and dynamic light scattering (DLS). For instance, the size distribution of nanoparticles can be estimated using KDE to better understand the synthesis process and optimize it for desired outcomes.
