How Do Size and Shape Influence Nanomaterial Properties?
The size and shape of nanomaterials significantly influence their physical and chemical properties. For example, gold nanoparticles exhibit different colors depending on their size due to the phenomenon of surface plasmon resonance. Similarly, the shape of nanoparticles, such as spherical, rod-like, or cubic, can affect their surface area and reactivity, impacting their effectiveness in applications like catalysis and drug delivery.
