Overcoming the Challenges of Using Graphene for Sensing Applications

Hamza Shakeel, Queen's University Belfast

Graphene has been touted as a wonder material since its discovery two decades ago. However, one of the downsides of graphene for sensing applications is its tendency to adsorb water molecules. This significantly reduces the performance of graphene sensors within hours after being first exposed to the ambient environment.

In this talk, I will present two different approaches to get the best use out of graphene as a sensing material. In the first approach, I will discuss how periodic UV illumination can be used to improve the adsorption properties of graphene for chemical sensing applications. In the second part of the talk, I will show how a simple Wheatstone bridge architecture can be implemented using a graphene foundry process for respiratory sensing applications.

Graphene as a platform for sensors

Amaia Zurutuza, Graphenea

Graphene’s electronic and mechanical properties make it an ideal candidate to be applied in various types of sensors. The market for sensors is extremely large since it includes many industries such as automotive, electronics and healthcare among others. Therefore, it is an excellent starting point for graphene applications. During this talk, I will cover the potential of graphene as a platform for sensor applications including gas, ion and biosensors. 

Graphene sensors for single cell antibiotic sensitivity testing

Aleksandre Japaridze, Soundcell

Antimicrobial resistance, the ability of micro-organisms to become resistant to antibiotics is a rapidly rising problem. The number of deaths due to this global problem is staggering; the number of deaths is expected to surpass 10M per year by 2050. To combat this crisis, development of novel Antibiotic Susceptibility Testing (AST) tools is key. This is because conventional AST tools are too slow, are pathogen growth rate dependent and typically requires from a single day, up to several weeks.

At SoundCell, we have developed a breakthrough technology that can potentially reduce the time for prescribing the correct antibiotic from few days to only 1 hour. The technology uses laser interferometry to detect nano-scale vibrations (nanomotion) induced by single micro-organisms on ultra-thin graphene biosensors. Using this technology, we have showed that the nanomotion of alive and dead bacteria are different [1]. This has allowed us to uniquely assess the effectiveness of antibiotics in bacterial infections in only 1 hour.  In my talk I will discuss the recent advancement regarding the technology and the tests by using pathogenic microorganisms.
