The shape of nanomaterials can profoundly impact their properties and functionalities. Common shapes include nanorods, nanotubes, nanospheres, and nanocubes. For example, nanorods have a higher surface area compared to spherical nanoparticles, which makes them more effective in catalysis and drug delivery. The shape also affects the way nanoparticles interact with cells and tissues, influencing their biocompatibility and toxicity.
