Applied NanoFluorescence


Welcome to Applied NanoFluorescence

Applied NanoFluorescence, LLC (ANF) manufactures and sells state-of-the art optical instruments to detect, characterize, and quantify nanomaterials, especially single-walled carbon nanotubes (SWCNT) and other near-infrared fluorophores in bulk samples (e.g. Ag2S and PbS quantum dots). Our analyzers offer the highest sensitivity available plus sophisticated software that automatically deduces and reports detailed sample compositions.

ANF was founded in Houston in 2004 by Professor R. Bruce Weisman of Rice University. Dr. Weisman serves as President. ANF's Chief Scientific Officer is Dr. Sergei M. Bachilo. Weisman and Bachilo are internationally recognized as the pioneering researchers who led the discovery and interpretation of fluorescence spectra from single-walled carbon nanotubes. The products offered by Applied NanoFluorescence embody these scientists' deep expertise in spectroscopic instrumentation and analysis.

Do you work with near-infrared fluorophores such as carbon nanotubes (CNT) and quantum dots (QD)?

Then you need a NanoSpectralyzer. Here's why:

  • CNT Producers can use these instruments to monitor batch-to-batch consistency and quality.
  • Customers who buy nanotubes can use a NanoSpectralyzer to assess the quality of incoming CNT material.
  • Biomedical & Environmental Researchers can exploit the NanoSpectralyzers’ very high NIR fluorescence sensitivity to detect and quantify trace concentrations of SWCNTs,PbS QDs or Ag2S QDs in complex surroundings.
  • Educators can use the NanoSpectralyzer in undergraduate and graduate curricula as a way to expose students to innovative, cutting-edge research topics.
