(57) [Summary]nA semiconductor nanocrystal compound, which can be linked to one or more affinity molecules, and (1) provide one or more semiconductor nanocrystals that can provide a second energy in response to exposure to the first energy; and One or more linking agents having a first moiety linked to one or more semiconductor nanocrystals and a second moiety capable of linking to one or more affinity molecules. One or more semiconductor nanocrystal compounds, linked to one or more affinity molecules, linked to a semiconductor nanocrystal probe, and capable of binding to one or more detectable substances in the substance to be analyzed; A second energy may be provided in response to one energy. The probe may emit a narrow wavelength band of electromagnetic radiation and / or may absorb, scatter, or diffract energy if induced by a narrow or wide bandwidth electromagnetic radiation source, or particle beam. |
