Upconverting Nanoparticles for Authentication, Biological & Solar Applications    

Ssynthesis, characterization and spectroscopy of upconverting lanthanide-doped NaYF4 nanoparticles or nanocrystals (NCs).


The synthesis and spectroscopy of upconverting nanocrystals has garnered a tremendous amount of attention recently due, among others, to their potential use as biolabels and in biological assays. Upconversion is a process where low energy light, usually near-infrared (NIR) or infrared (IR), is converted to higher energies, ultraviolet (UV) or visible, via multiple absorptions or energy transfers.

The technology entails the synthesis, characterization and spectroscopy of upconverting lanthanide-doped NaYF4 nanoparticles or nanocrystals (NCs). Monodisperse cubic NaYF4 NCs were synthesized via a thermal decomposition reaction. Colloidally stable solutions of NaYF4 NCs can be obtained. Oxides and garnets are also available.

Primary Application of the Technology

Potential use as biolabels and in biological assays.
Ideal for fluorescence resonance energy transfer
(FRET) applications.
Can be adapted to energy transfer applications (solar energy).

Competitive Advantage

• The synthetic method uses technical-grade solvents and ligands; no sophisticated equipment or complicated procedure needed.
• Produces highly luminescent and uniform NCs; (27.6 nm ± 1.6)
• The colloids of the lanthanide-doped NCs exhibit green/red and blue upconversion luminescence
• No background signal in biological samples
• No photobleaching
• NCs can be excited with a 980 nm laser diode with low power densities (low cost)

Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 436: Chemistry: Analytical And Immunological Testing

This is the generic class for: chemical test standards, analytical compositions, and processes which involve a chemical reaction for determining qualitatively or quantitatively the presence of a chemical element, compound or complex in a composition or a chemical compound, or an element or radical in a compound; processes for analysis which involve an in vitro antigen-antibody, immunological or protein binding interaction other than those involving a living antigen, or enzyme label; and processes of analysis or study of the chemical properties of a sample; the physiological effect of a sample; or chemical determination of a physical property of a sample. Compositions and their mere methods of use of thermoparticulating compositions. Combinations of tests or measurements with methods of regulating a chemical reaction not otherwise provided for in a chemical synthesis class or otherwise.
