| dc.description.abstract | The colloidal synthesis of CdSe/ZnSe core/shell quantum dots
(QDs) under nitrogen gas flow is presented in this study. The
optical, morphology and structural properties of CdSe/ZnSe
core/shell QDs are varied by changing the growth temperature
and the cadmium source (Cd2+). The Fourier transform infra-red
studies validate that CdSe/ZnSe QDs capped with functional
COOH groups were formed. The morphological and composition
studies conducted using high resolution transmission
microscope, selected area electron diffraction andenergy dispersive
spectroscope confirmed the formation of pure and
mono-disperse QDs while photoluminescence and ultra-violet
visible spectroscopy displayed their improved fluorescent
properties. Caco-2 cell line was cultured from colon cancer and
cytotoxic studies were conducted to test for cell viability of
various capped 3-MPA CdSe/ZnSe QDs at various concentrations.
The formed CdSe/ZnSe QDs prominently bear the zincblende
structure with their particle size lying well below the
Bohr excitation radii. Their hydrophilic nature and the availability
of functional groups on the CdSe/ZnSe QDs makes them
excellent potential labeling and therapeutic agents for the
colon cancer disease diagnosis. | en_US |
