Lateral Flow Assay Particles

Surflay's Fluorescent / Phosphorescent Lateral Flow Assay Particles

Surflay's LFAs maintain the following properties:

  • Monodisperse with Optimal Size
  • A broad choice of excitation and emission wavelengths
  • Time-resolved emission

A development away from the traditional Gold Nanoparticles for Lateral Flow Assay purposes - Surflay succeeded in achieving:

  • 150-300nm Latex beads with customized surface chemistry.
  • High brightness for a set of five different emissions at 360 nm excitation wavelength.


Surflay's Optimization Parameters

  • Screening for the Optimal Antibody using our WhisperSense.
  • Particle brightness and Distribution using Confocal Laser Scanning Microscopy.
  • Particle diameter, density, and monodispersity using CPS Disc Centrifuge.
  • Particle stability, and hydrodynamic diameter using Zetasizer.
