  • 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 Available Products:

a) Luminescent particles

b) Semiconductor particles

c) Gold particles

d) Silver particles

e) Copper particles

f) Quantum dot beads

g) Cadmium free quantum dots

h) Water soluble quantum dots 

  • Quantum Dots Dominant Raw Materials Used:

a) Cadmium selenide 

b) Lead selenide
c) Lead sulfide

d) Lead telluride 
  • Quantum Dots Nominal Particle Size:

         5 to 50 nanometers
  • 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.

  • Quantum Dots TSCA (SARA Title III) Status:

Varies. For further information please call the E.P.A. at +1.202.554.1404

  • NIOSH Strategic Plan For Nanomaterials Research:

  • Quantum Dots Safety Notice:

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.
 
c) You can contact the Center For Disease Control (CDC) at +1–800–232–4636 or by email at:

d) Premanufacture Notice (PMN): Quantum dots and nano dots purchased from READE are to be used only for R&D applications.
 

  • Domains Of Nanoparticles & Clusters With Different Structures:

a) Molecules= (~1 to 10 atoms)

b) Clusters= (~10 to 103 atoms)

c) Particles= (~103 to 105 atoms) 

d) Bulk= (~105 atoms and larger) Source: University of Texas at Austin
