Paper Abstract

We present the luminescence properties of CdS nanoparticles conjugated with active DNA molecules. Having the action of activators, CdS nanoparticles combine with DNA molecules easily and tightly. The fluorescence from CdS nanoparticles is characteristics of bright spots under dark optical microscopy, indicating that CdS nanopaticles can be used labeling DNA molecules. Strong photoluminescence emission of A-DNA-CdS keeps relatively steady at room temperature in terms of the time behavior of optical bleaching, showing that CdS nanoparticles are suitable to long time biological analysis and detection.
