Abstract
Methods for using semiconductor nanocrystals for determining fluid movement, fluid dilution and fluid removal are described. Methods for using semiconductor nanocrystals for monitoring and quantifying the amounts of solid materials dissolved in a liquid are also described.
Claims16
A method comprising:
- providing a first composition having a first fluid therein;
- providing a second composition having a second fluid therein, wherein said second composition includes a predetermined amount of luminescent semiconductor nanocrystals capable of emitting electromagnetic radiation in a narrow wavelength band when excited;
- transferring all or a portion of said second composition into said first composition to form a third composition;
- exposing said third composition to energy capable of exciting said luminescent semiconductor nanocrystals;
- detecting the electromagnetic radiation emitted from said luminescent semiconductor nanocrystals in said third composition;
- and
- quantifying the luminescent semiconductor nanocrvstals in said third composition to verify the volume of said second composition into said first composition to form said third composition.
