Graphene in Health

Traditionally, biosensors, such as the types used in blood glucose testing use metallics and carbon materials. The use of graphene in these biosensor diagnostic tools aims to reduce the metallics used to improve costs and the environmental impact.

Graphene possesses attractive qualities for sensors and biosensors, such as ultra-high charge mobility, transparency, large surface area, non-toxicity, high-tensile strength, and high thermal conductivity to name a few.

Detection at the Nanomaterial Level

Graphene-based biosensors for detecting biomolecules with technologies such as enzyme biosensors, DNA biosensors and immunosensors are an area of promise. Graphene is a perfect substrate for doping, making it an ideal biosensor for detecting biomarkers, DNA and proteins.

In addition to its sensitivity, graphene provides excellent mechanical strength, thermal and electrical conductivity, compactness, and a potentially low cost, all desirable characteristics when it comes to the sensor market.

Other Sensor Technologies

Key applications for graphene sensors include food, water quality, chlorine, pH, indoor and outdoor air monitoring, agriculture, and security.

Given the two-dimensional structure of graphene the entire material volume acts as a sensor surface, which can be used in advanced 2D material-based sensors for potential use as humidity sensors, gas sensors, biosensors, and strain sensors.
