Graphene-based sensors

The large surface area of graphene means it is very sensitive to molecules that contact its surface, which makes it ideal for use in sensors. With our in-house-designed environmental chamber, we perform a variety of electrical transport measurements on sensors in a controlled atmosphere, with variable gas content , temperature and humidity . We can also run AFM based experiments in a controlled environment, to investigate how atmospheric changes affect the structural and electronic properties of quantum materials. We investigate and develop graphene-based sensors, including gas sensors to detect harmful pollutants such as NO2 , CO and CO2.

We also develop novel biosensors which could detect hepatitis biomarkers, allergens  and other disease-carrying pathogens.

Some highlights of our research include

Real-time detection of Hepatitis B Virus using a hybrid graphene-gold nanoparticle biosensor

A facile method for the non-covalent amine functionalization of carbon-based surfaces for use in biosensor development
