Wave-Particle Duality of Light: Quantum Dot Research at MIT See Lecture 3 for a description of the wave-particle duality of light. Example from page 5 of Lecture 3 notes following a description of the relationship between the wavelength ( λ ) and frequency ( ν ) of light: λν = c = 2.9979 x 10 8 ms -1 Quantum dots are fluorescent nanoparticles of semiconductor material. Their small size and favorable fluorescent properties (such as intense brightness) make them ideal candidates for biological and medicinal imaging applications. For example, chemical attachment of quantum dots to specific cell types, such as cancer cells, may lead to important advances in imaging cancer. By shining UV light onto the area near a tumor and detecting the light emitted from the quantum dots, a surgeon could unambiguously visualize tumor cells.
