Waveguide Biosensor

Rapid and sensitive detection of disease-associated biomarkers in an immunoassay format using a waveguide-based optical biosensor. 

LAUR: 16-22501

Benefits/Features

  • Self-assembled Monolayers- They are stable, specific, and robust silane-based surfaces used for waveguide functionalization that reduce nonspecific binding of biomarkers and enhance the signal detection.
  • Membrane Insertion- This approach utilizes the natural chemical interactions of an amphiphilic target with lipid bilayers thereby enabling them to partition into membrane mimetic surfaces.
  • Lipoprotein Capture- This exploits the association of lipid targets with lipoproteins to capture and detect lipid biomarkers.
