- Abstract
The article comments on the use of quantum dots as photosensitizers. Quantum dots are compounds with constant composition. Their synthesis is relatively simple and inexpensive. They are not cytotoxic in the absence of light, but have a potential to induce cytotoxicity under UV irradiation. Intracellular delivery of quantum dots can be facilitated by surface coatings and they can be functionalized to be both water soluble and biocompatible. The synthesis of different immunocompatible quantum dot bioconjugates can guarantee their specific localization into target tissues. They can be precisely tuned from the UV to the infrared region of the spectrum by changing their size and composition.
