OpenSPR Sensors

Optimize easily with a wide-range of affordable sensor chips

Sensor Chips

sensor-chip

Our nanotechnology enabled sensors are manufactured to the highest quality to ensure consistent and repeatable measurements, at half of the price of traditional sensors. We achieve less than 2% CV on all critical optical properties. Our sensors are stable in a variety of solvents, buffers and reagents.

Surface Chemistries

OpenSPR sensor surfaces are available as plain gold surfaces for custom surface functionalization or with a variety of functional surface chemistries. These sensor chips reduce the time and effort needed for immobilization while improving repeatability.
  • Carboxyl - any amine group via EDC/NHS
  • NTA - his-tagged targets
  • Biotin - biotin tagged targets
  • Steptavidin - streptavidin coupled targets
  • GST - GST-tagged biomolecules/proteins
  • Protein A - IgG based antibodies
  • Amine - any carboxyl group via EDC/NHS
  • Liposome Binding (LIP) - liposomes/membrane proteins
  • Hydrophobic (MEM) - lipid monolayer
  • Thiol - maleimide-taged ligands
  • Standard Gold - non-functionalized and perfect for custom surface chemistry development and ligands with thiol groups
