Abstract: High quality CdS quantum dots (CdS QDs) with a narrow size distribution have been synthesized through a reverse micelle route. Chemical modification and folate-functionalization of the QDs resulted in the bio-targeted fluorescent quantum dots(QDFs). Transmission electron microscopy (TEM) and photoluminescence emission spectroscopy were employed to characterize the morphologies and the optical properties of the QDs. Observation on the incorporation of QDFs with tumor cells (HepG2) under laser confocal fluorescent microscopy indicated that the QDFs could successfully identify the target tumor cells with high expression levels of folate receptor. |
