SPR Sensor chips

XanTec bioanalytics provides laboratories worldwide with the ultimate in SPR biosensor chips via superior coating technologies. Our proprietary technology, developed over more than 25 years ago, solves a number of critical issues usually associated with state of the art Self Assembled Monolayer (SAM) surface chemistry. The coatings are robust and prevent exposure of hydrophobic nanodomains or pinhole defects which can cause non-specific interactions. As the chemistry is extremely versatile, a large choice of topcoats is available to specifically address different experimental needs.

Not only do we feature the largest portfolio of sensorchip coatings and chemistries in the world, we offer the versatility to work on a number of different instruments and in varying formats. The chips fit into instruments of all major manufacturers. In addition, we provide customized sizes or can coat alternative substrate materials.
