Presentation Transcript

  1. Optical UpconvertingNanoparticles for Biological Applications Alain Richard, Ph. D. Director, Commercialization Life Sciences Valeo Management L.P. Principal Investigator: John Capobianco, Ph.D. Concordia University

  2. Technology Synthesis, characterization and spectroscopy of upconvertinglanthanide-doped NaYF4 nanoparticles (NPs). Monodisperse cubic NaYF4NPs were synthesized via a thermal decomposition reaction. Other particles are available.

  3. Technology

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

  5. Market Applications Detection & Imagery: Potential use as biolabels and in biological assays. Ideal for fluorescence resonance energy transfer (FRET) applications. Authentication (e.g. in the ink for bank notes). Food Safety: A technology development project for the detection of foodpathogensis under way with ITEGA in Montreal (Institut de technologie des emballages et du génie alimentaire). We are seeking an industrialpartner in food packaging. OTHERS: Can be adapted to energy transfer applications (solar energy).

  6. Proof Points 1- Authenticity: Nanoparticles have been incorporated successfully into ink. 2- The technology has been adapted to water-soluble applications (biological assays; e.g. electrophoresis). 3 -Current project in food safety (pathogen detection)

  7. Business Opportunities • Licensing opportunities : all fields currently available • Patent issued in the USA and patent-pending in Canada • Seeking industrial partners; in food packaging, authenticity, biological detection: e.g. diagnostics • Please contact: • Alain Richard, Ph.
