Graphene biosensing in SPR

Sensia has developed the first commercial graphene biosensors. Their conception of the optical system enables extreme versatility, allowing the indifferent use of gold biosensors, of graphene coated biosensors, and of silica coated biosensors. The combination of graphene biosensors and of nanoparticles in SPR device, leads to new unattained limits of detection, getting into the attomolar range.
