Ultra-Sensitive, Multi-functional Applications

Graphene is very sensitive to change. Its unique molecular structure gives it a surface that promotes the adsorption of molecules. This matched with graphene’s conductive and thermal abilities enables it to easily ‘sense’ molecules and fields making it the ideal material for composite or single-material sensors. By functionalising graphene, it’s structure and properties can be manipulated to change its sensitivity and hence response to different applications.

Paragraf’s Unique Approach

To achieve high performance, the final application of a sensing device requires specific, targeted properties from the graphene used in the sensor. It is possible to achieve this by altering the properties of the graphene layers through a process called functionalisation. Doping the carbon matrix of graphene with other elements and/or producing the graphene in a multilayer format allows altered physical and electronic properties to be induced in the graphene layers.

Paragraf’s graphene generation technique incorporates the ability to add elemental and molecular dopants in parallel with multi-layer material formation, delivering ultimate flexibility in the properties of the graphenes that can be produced.

With the Paragraf approach harnessing the multifunctional physical and electrochemical abilities of graphene becomes possible. This enables the achievement of very high sensitivity to the desired detection function, be that biological, electrical, thermal or chemical. However, even more importantly combined sensing actions in a single device become possible.
