A novel and highly sensitive biosensor employing graphene oxide nano-sheets (GO), multiwalled carbon nanotubes (MWCNTs), and pyrogallol (PG) was fabricated and utilized for the sensitive determination of omeprazole (OME).
We demonstrate a highly sensitive Au-MoS2-Graphene based hybrid surface plasmon resonance (SPR) biosensor for the detection of DNA hybridization.
As a material highly sensitive to the environment, graphene could act as a sensor with a single device measuring strain, gas, magnetism or pressure.
Since the electronic properties of graphene are highly sensitive to the defects and number of layers in graphene sample, it is desirable to develop tools to engineer these two parameters.
Graphene is highly sensitive to environmental influences, and thus, it is worthwhile to deposit protective layers on graphene without impairing its excellent properties.
However, graphene is highly sensitive to extraneous environmental influences.
The 2D band is highly sensitive to the stacking of graphene, and the intensity ratio of 2D band to G band (I2D/IG) is an important parameter to evaluate the layering of graphene materials [42, 43].
Mao et al. fabricated a highly sensitive FET biosensor using thermally reduced graphene oxide (TRGO) sheets functionalized with Au NPs.
Complementary research is presented to prove that graphene oxide is highly sensitive to unintended modifications during standard measurements.
As the surface is directly exposed to the ambient environment, the electrical property of graphene sheets is highly sensitive to the external disturbance.
