Claim Text:
1. A method to determine the presence of a photon producing luminescent biological marker in a cell, tissue or organism of interest comprising the steps: a) providing conditions suitable for said biological marker to produce at least one first photon; b) providing a Fluorescence by unbound excitation luminescence Probe Pair-Upper (FPP-U), wherein said FPP-U is selected from the group consisting of quantum dots, carbon nanotubes, fluorescent proteins, diamond nanocrystals, and metalloporphyrins; and wherein said at least one first photon of step a) excites said FPP-U, which emits at least one second photon; c) detecting said at least one second photon; wherein said biological marker and said FPP-U are not bound and each of said at least one second photon is of a longer wavelength than each of said at least one first photon.
