Optical molecular sensing with semiconductor quantum dots (QDs)

Freeman, Ronit, Willner, Itamar·2012·Chemical Society Reviews

Abstract

Semiconductor quantum dots (QDs) exhibit unique optical and photophysical properties. These features are implemented to develop optical molecular sensor systems. The review addresses the methods to functionalize the QDs with chemical capping layers that enable the use of the resulting hybrid structures for sensing, and discusses the photophysical mechanisms being applied in the different sensor systems. Different methods to design the chemically-modified QDs hybrid structures for sensing low-molecular-weight substrates, metal ions, anions and gases are presented. These include the functionalization of the QDs with ligands that bind ions, the modification of the QDs with substrate-specific ligands or receptor units, and the chemical modification of the QDs upon sensing. Specific emphasis is directed to describe the cooperative catalytic functions of the QDs in the sensing processes, and to address the function of sensing with logic-gate operations.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
