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.
Claims15
A method for verifying the transfer of a plurality of fluids to a container, comprising:
- providing a plurality of compositions having fluid therein wherein each member of said plurality of compositions includes a predetermined amount of different luminescent semiconductor nanocrystals capable of emitting electromagnetic radiation at different wavelength bands corresponding to said luminescent semiconductor nanocrystals when excited;
- transferring all or a portion of said plurality of fluids into said container;
- exposing said container to energy capable of exciting said luminescent semiconductor nanocrystals;
- detecting the electromagnetic radiation emitted from said plurality of luminescent semiconductor nanocrystals to determine the transfer of said plurality of fluids;
- and
- quantifying the luminescent semiconductor nanocrystals to verify the delivery amount of said plurality of compositions into said container.
