The Development of Immunochromatographic Technology Two stage Visualization (Colloidal Gold immune test technology) Luminescence Four generation products CG Qualitative CG Semi-Quantitative Immunofluorescence Quantitative Up-converting Phosphor Quantitative

The Development of Immunochromatographic Technology First stage：Pigmentation particles（CG） The first generation product：CG Qualitative （HCG strip） Low sensitivity and less. Test specifity Visual inspection inaccuracy The. Test second generation product：CG Semi-quantitative results difficult to archive （color card or instrument）

The Development of Immunochromatographic Technology Second stage：Luminescent particles Luminescence background interference Third generation product：Fluorescence Quantitative Immunoassay analyzer Photobleach or Fluorescence fade Quantitative not accurate

The Development of Immunochromatographic Technology The Latest generation product Up-converting Phosphor(UCP)

2. UCP Technology Normal Fluorescent materials The luminescent material Up-converting Phosphor materials Artificially synthesized rare-earth-doped material, not exist in nature.

Up-converting phosphor particles: Rare-earth elements synthesized nonomaterials Rare-earth element (17): La、Ce、Pr、Nd、Pm、Sm、Eu、Gd、Tb、Dy、Ho、Er、 Tm、Yb、Lu；Sc and Y； UCPs: Usually submicron particles, made from rare-earth-doped ceramics and offen coated with silica for broader bio/chemical compatibility and ease of surface functionalization.

UCP Technology UCPs unique property: Optical up-conversion: The emission of light as a significantly shorter wavelength than that of excitation Exactly correspond with Anti-Stokes principle

UCP Technology Ø Stokes law (Stokes fluorescence): Ø Stokes fluorescence is the re-emission of longer wavelength photons (lower frequency or energy) by a molecule that has absorbed photons of shorter wavelengths (higher frequency or energy). Ø For example: Ultraviolet been excitation then re-emission the visible light. Ø Down-converting phosphors v Anti-Stokes fluorescence v Up-converting Phosphors
