Paper Abstract
Medicinal applications of luminescent semiconductor quantum dots are of growing interest. In spite of the fact that their
fabrication and imaging applications have been extensively investigated for the last decade, very little is documented on
photodynamic action of quantum dots. In this study we demonstrate generation of singlet oxygen and other radical
species upon exposure of quantum dots to blue light and therapeutic red light. Extent of radical production can be
readily modified by antioxidants. Lay and scientific communities are two sites concerning potential hazards and
enthusiastic applications of nanotechnology. Synthesis of quantum dots composed of less toxic materials is of great
interest. A new candidate is a ubiquitous element carbon, which on nanoscale exhibits strong photoluminescence.
