Devices, systems, methods (as depicted in figure 1a), and compositions of matter can track and/or identify a library of elements, particularly for use with fluids, particulates, cells, and the like. Signals from one or more semiconductor nanocrystals may be combined to define spectral codes. Separation of signal wavelengths within dedicated wavelength ranges or windows facilitates differentiation of spectral codes, while calibration signals within the spectral codes can avoid ambiguity. Modeling based on prior testing can help derive libraries of acceptable codes.

L'invention concerne des dispositifs, des systèmes, des procédés et des compositions qui permettent de poursuivre et/ou d'identifier une bibliothèque d'éléments, destinés notamment à être utilisés avec des fluides, des matières particulaires, des cellules, etc. Des signaux émis par un ou plusieurs nanocristaux de semi-conducteur peuvent être combinés afin de définir des codes spectraux. La séparation des longueurs d'onde des signaux dans des gammes ou fenêtres spéciales de longueurs d'onde facilite la différenciation des codes spectraux, tandis que les signaux de calibrage compris dans les codes spectraux permettent d'éviter toute ambiguïté. Une modélisation basée sur des tests préalables peut contribuer à dériver des bibliothèques de codes acceptables.
