One of the primary ways to tune nanomaterials is by adjusting their size and shape. For example: - Size: The optical properties of gold nanoparticles can be tuned by changing their size. Smaller particles tend to absorb and scatter light differently compared to larger ones. - Shape: The shape of nanomaterials, such as rods, spheres, or cubes, can influence their surface area and reactivity. For instance, nanorods may have different catalytic properties than nanospheres.
