title: Host-molecule-coated quantum dots as fluorescent sensors.
abstract: "Host" molecules, containing a binding site that is highly specific for an analyte "guest," are used as sensors to register analyte binding through a variety of mechanisms such as colorimetric, fluorescent, or electrochemical signals. There is increasing interest in the host-guest chemistry on the surface of quantum dots (QDs) and in the changes that it produces in the luminescent properties of QDs. The bulk of this study focuses on those QDs with bound host molecules (crown ether, cyclodextrin, calixarene, and porphyrin) and the selectivity they display toward metal ions and small organic molecules.
