Semiconductor Quantum Dots as Two-Photon Sensitizers

摘要

Near-infrared (NIR) bioapplications of quantum dots (QDs) have been a research focus since it became evident that deeper penetration of tissues for imaging and sensitization applications is only accessible within the spectral therapeutic window of 700- 1200 nm. At shorter wavelengths cell chromophores and organelles absorb and scatter visible light, respectively. Contrary, at longer wavelengths the overtone vibrational absorption from water and melanin prevent penetration as well.
