The colloidal stabilities and emission properties of CdSe/ZnS quantum dot (QD) optical probes capped with a variety of thin, hydrophilic surface coatings were studied using confocal fluorescence correlation spectroscopy. These coatings are based on mercaptoethanol, mercaptopropionic acid (with and w
## Abstract We demonstrate the fabrication of thin silicaβcoated CdSe/ZnS colloidal quantum dots using a reverse microemulsion method. Spherical particles of <20βnm diameter with a single dot in the centre of a thin silica shell of good morphology are achieved, promising for biophotonic application
