NANOPLEX™ Rapid Immunoassay

NANOPLEX™ Rapid addresses the requirement for quantitative lateral flow immunoassays by providing an optical detection modality that is highly applicable to rapid point of care testing. Key advantages over existing lateral flow assays are:

  • Multiplexing capability in a single line in a sensitive lateral flow immunoassay (LFI) format
  • Colloidal gold composition, similar to that already used extensively in lateral flow devices, allows for ease of integration into existing LFI
  • Leverages the performance of surface-enhanced Raman scattering (SERS)
  • NANOPLEX™ biotags have a convenient, glass encapsulated format which allows simple biofunctionalization with proteins and nucleic acids
  • Near IR detection minimizes sample background interference. Devices can therefore be read in the presence of whole blood and other biological matrices
  • Benchtop reader and proprietary software for data analysis

** Chicken embryo infectious dose at which 50% of the embryos perish

Multiplexing Benefits
  • Simultaneous identification and quantitation of multiple analytes in a single line
  • Optimization of performance through the use of an additional tag as an internal calibrant

Quantitation of three analytes (Flu A, Flu B, RSV) simultaneously from a single line

Multiplexed Technology

Assays perform independently without cross-talk

Multiplexed Technology

Use of an additional tag as internal control leads to reduction in %CV and thus provides robust quantitation
