Bioelectronics with graphene nanostructures

pH-induced on/off-switchable graphene bioelectronics

On/Off-switchable zipper-like bioelectronics on a graphene interface.

An on/off-switchable graphene-based zipper-like interface is architectured for efficient bioelectrocatalysis. The graphene interface transduces a temperature input signal into structural changes of the membrane, resulting in the amplification of electrochemical signals and their transformation into the gated transport of molecules through the membrane.

Inorganic Nanostructures Decorated Graphene

Programmable bioelectronics in a stimuli-encoded 3D graphene interface.

The ability to program and mimic the dynamic microenvironment of living organisms is a crucial step towards the engineering of advanced bioelectronics. Here, we report for the first time a design for programmable bioelectronics, with 'built-in' switchable and tunable bio-catalytic performance that responds simultaneously to appropriate stimuli. The designed bio-electrodes comprise light and tem...

Edge plasmons in graphene nanostructures

Plasmon modes in graphene are influenced by the unusual dispersion relation of the material. For bulk plasmons this results in a n1/4 dependence of the plasma frequency on the charge density, as opposed to the n1/2 dependence in two-dimensional electron gas (2DEG); yet, bulk plasmon dispersion in graphene follows a similar q1/2 behavior as for other two-dimensional materials. In this work we co...
