Abstract:
The overall focus of the thesis involves the synthesis and
characterization of CdSe QDs overcoated with shell materials for various
biological and chemical sensing applications. Second chapter deals with the
synthesis and characterization of CdSe and CdSe/ZnS core shell QDs. The
primary attention of this work is to develop a simple method based on
photoinduced charge transfer to optimize the shell thickness. Synthesis of
water soluble CdSe QDs, their cytotoxicity analysis and investigation of
nonlinear optical properties form the subject of third chapter. Final chapter
deals with development of QD based sensor systems for the selective
detection of biologically and environmentally important analytes from
aqueous media.
