Abstract

The graphene market continues to expand across a range of applications including consumer electronics, sensors, flexible wearables, supercapacitors, conductive inks and coatings. Thanks to graphene’s extraordinary electrical and mechanical properties a new generation of rapid, sensitive, low-cost bio/chemical sensors can be envisaged with impact upon healthcare, drug discovery, and bio/chemical detection applications. Here we present the graphene-related R&D work at RISE Acreo with focus upon three objectives: graphene materials including wafer scale graphene-on-SiC, chemically synthesized graphene oxide (GO), reduced graphene oxide (RGO) and graphene quantum dots (or carbon nano particles); design and fabrication of the graphene devices, especially on their multiplexed sensing capability for enabling detection of multiple targets on a miniature integrated chip; and analysis of sensing mechanisms. A few sensor examples will be described in this work, one is a graphene sensor to monitor glucose for diabetes. Another is a dopamine (DA) sensor utilizing graphene/ZnO-tetrapod hybrids for early diagnosis of Parkinson diseases (PD). DA is an important biomarker in the serum of patients with PD. The third one is a proton transmission detector utilizing 3D graphene onto SiC, which can initiate a new application for the detection of ionizing particle irradiation onto living cells. Finally, graphene sensors for forensic applications will be addressed; for instance, detection of amphetamine and TNT has been explored, aiming at rapid onsite crime scene analysis. In addition, a comprehensive analysis of the market and commercial opportunities of these devices will be presented.
