Sorting nanoparticles is vital for several reasons. Firstly, the properties of nanoparticles can significantly vary with size and shape, influencing their behavior and functionality. Secondly, for applications such as drug delivery, biosensors, and catalysis, uniformity in nanoparticle dimensions ensures consistent performance and reliability. Finally, sorting is essential for the purification of synthesized nanoparticles, removing unwanted by-products and ensuring high-quality materials.
