The structure of nanomaterials, including their shape, composition, and surface characteristics, is pivotal in determining their functionality. For example, nanoparticles can be spherical, rod-shaped, or even have more complex geometries. Each shape offers distinct advantages: spherical nanoparticles are often used in drug delivery due to their uniformity, while rod-shaped nanoparticles may exhibit different optical properties. Similarly, the surface composition can influence how these particles interact with their environment, affecting their efficacy in various applications such as catalysis or sensors.
