The SPRi-Biochips™ are suitable for a range of surface chemistries and are not restricted to a single probe/target regime. The biochips are easily adapted for specific processes.
We can offer you:
Pre-functionalized surfaces - ready-to-use
Electroaddressing of your molecules onto the biochip - we do it for you
Training on our surface chemistry
