Abstract: An apparatus comprising: a channel (4) configured to conduct charge carriers; and a charge carrier generator (22) configured to generate charge carriers for populating the channel, wherein the charge carrier generator is configured for resonance energy transfer (FRET). The charge carrier generator may be a nanoparticle or quantum dot (22), functionalised with at least one moiety (28A, 28B) to enable detection of an analyte. The charge carrier generator may also be a nanoparticle or quantum dot (22) configured to photo-generate charge carriers. The channel (4) may be made of a material having a very high carrier mobility like graphene or carbon nanotubes.

Abstract: A percolation network of functionalised reduced graphene oxide flakes, the percolation network configured to allow for hopping of charge carriers between adjacent reduced graphene oxide flakes to enable a flow of charge carriers through the percolation network, and wherein the reduced graphene oxide flakes are functionalised to facilitate detectable changes in the flow of charge carriers in response to a stimulus to the percolation network.
