How Do Optical Properties Change?

The optical properties of materials can also be dramatically altered at the nanoscale. Quantum dots are a prime example; they exhibit size-dependent emission spectra, meaning their color changes with size. This property is incredibly useful in bioimaging and display technologies. Plasmonic nanoparticles, such as gold and silver nanoparticles, show unique optical properties due to localized surface plasmon resonance (LSPR), which can be employed in biosensing and photothermal therapy.
