Nanoparticle analysis involves studying particles that are smaller than 100 nanometers in size. These tiny particles can have unique physical and chemical properties, making them important in various fields such as medicine, electronics, and environmental science. Techniques like scanning electron microscopy and dynamic light scattering are commonly used to characterize their size, shape, and distribution. Understanding nanoparticles is crucial for developing new materials and technologies. For instance, in drug delivery, nanoparticles can be engineered to transport medications directly to targeted cells, improving treatment effectiveness. Additionally, analyzing nanoparticles helps assess their safety and environmental impact, ensuring responsible use in various applications.
