The surfaces of colloidal nanocrystals are complex interfaces between solid crystals,
coordinating ligands, and liquid solutions. For fluorescent quantum dots, the properties of …

Bio‐conjugated nanoparticles have emerged as novel molecular probes in nano‐
biotechnology and nanomedicine and chemical analyses of their surfaces have become …

Surface traps, such as electron and hole traps, quench the photoluminescence (PL) of
semiconductor nanocrystals. We find a binary ligand system that effectively passivates those …

Blinking of zinc blende CdSe-based core/shell nanocrystals is studied as a function of shell
materials and surface ligands. CdSe/ZnS, CdSe/ZnSe/ZnS and CdSe/CdS/ZnS core/shell …

In the biological sciences, the use of core− shell quantum dots (QDs) has gained wide
usage but analytical challenges still exist for characterizing the QD structure. The application …

We report an analysis method to identify conjugated ligands and their binding states on
semiconductor nanocrystals based on their molecular information. Surface science …

Chemical characterizations of biochemically functionalized single nanoparticles are
necessary to optimize the nanoparticle surface functionality in recently advanced …

Blinking of zinc-blende CdSe/ZnS core/shell nanocrystals are studied as a function of
surface passivating ligands. Organic-soluble CdSe/ZnS core/shell nanocrystals are …

The synthesis and determination of the structure of a Förster resonance energy transfer
probe intended for the detection of specific nucleic acid sequences are described here. The …

Analysis of substrates directly on solid phase resins without the need for separate cleavage
conditions remains an outstanding challenge in the field of solid phase synthesis. We now …
