Semiconductor Quantum Rods as Single Molecule Fluorescent Biological Labels In this paper, we report the development of rod-shaped semiconductor nanocrystals (quantum rods) as fluorescent biological labels. Water-soluble biocompatible quantum rods have been prepared by surface silanization and applied for nonspecific cell tracking as well as specific cellular targeting.

Semiconductor nanocrystals as fluorescent biological labels. Semiconductor nanocrystals were prepared for use as fluorescent probes in biological staining and diagnostics. Compared with conventional fluorophores, the nanocrystals have a narrow, tunable, symmetric emission spectrum and are photochemically stable. The advantages of the broad, continuous excitation spectrum were demonstrated in a dual-emission, single-excitation labeling experiment on mouse fibroblasts.

The quantum dot-labeled molecules remain active for biochemical reactions and the tagged species produce brightly colored products [7, 8]. This methodology takes advantage of the efficient fluorescence and high photostability of the semiconductor quantum dots, representing a new class of biological dyes.

Semiconductor nanocrystals as fluorescent biological labels. Semiconductor nanocrystals for biological imaging - ScienceDirect Semiconductor nanocrystals (see glossary), also called quantum dots (QDs), are a new class of fluorescent biological labels. Originating from quantum confinement (see glossary) of electrons and holes within the nanocrystal core material, the fluorescence from QDs is unique compared with that from traditional organic fluorophores. For example, QDs exhibit high photostability, broad absorption, narrow and symmetric emission spectra (see glossary), slow excited state decay rates and large ...

Compared with conventional fluorophores, the nanocrystals have a narrow, tunable, symmetric emission spectrum and are 3C-SiC Nanocrystals as Fluorescent Biological Labels Abstract. Silicon carbide nanocrystals are water-soluble, chemically inert, and highly fluorescent, and they may be idealas biological labels. After the uptake of3C-SiC nanocrystals, human fetal osteoblast (hFOB) cells exhibit brightgreen-yellow fluorescence (see image).The nanoparticles show high resistanceagainst photobleaching with no significant cytotoxicity.
