Abstract:
We have studied the photodynamic properties
of novel CdTe quantum dots?methylene blue hybrid
photosensitizer. Absorption spectroscopy, photolumines-
cence spectroscopy, and fluorescence lifetime imaging of
this system reveal efficient charge transfer between nano-
crystals and the methylene blue dye. Near-infrared photo-
luminescence measurements provide evidence for an
increased efficiency of singlet oxygen production by the
methylene blue dye. In vitro studies on the growth of
HepG2 and HeLa cancerous cells were also performed,
they point toward an improvement in the cell kill efficiency
for the methylene blue-semiconductor nanocrystals hybrid
system.
