Quantum Dots General Descriptions:
a) Quantum dot particles are a new material that promise fundamental changes in biological labeling.
b) Quantum particles are tiny nanocrystals that are stable, water-soluble, and glow when stimulated by an external source such as ultraviolet (UV) light. They are made of semiconductor material such as cadmium selenide. Each individual quantum particle is nanoscopic (one billionth of a meter) in scale.
c) Something (usually a semiconductor island) capable of confining a single electron, or a few, and in which the electrons occupy discrete energy states just as they would in an atom (quantum dots have been called artificial atoms).

- Quantum Dots Typical Applications:
US researchers have observed optical gain and stimulated emission at room temperature in chemically-synthesized nanocrystal quantum dots. Based on II-VI materials, the development could lead to a new class of nanoscopic solid-state lasers. Potential applications include: research, drug discovery, diagnostics, biological reagents, genetic analysis, solid-state lighting, sensors, anti-counterfeiting, display screens, cosmetics, and solar cells.

- NIOSH Strategic Plan For Nanomaterials Research:
Visit this external NIOSH website
a) Before using quantum dots, the user shall determine the suitability of the product for its intended use, and user assumes all risk and liability whatsoever in connection therewith.
b) With the publication of the "Approaches to Safe Nanotechnology" document, NIOSH hopes to: raise awareness of the occupational safety and health issues involved with nanotechnology; make recommendations on occupational safety and health best practices in the production and use of nanomaterials; facilitate dialogue between NIOSH and its external partners in industry, labor and academia; respond to requests for authoritative safety and health guidelines; and, identify information gaps and areas for future study and research.
