Cell proliferation tracking using graphene sensor arrays

Daly, R and Kumar, S and Lukacs, G and Lee, K and Weidlich, A and Hegner, M and Duesberg, GS (2012) Cell proliferation tracking using graphene sensor arrays. Journal of Sensors, 2012. ISSN 1687-725X

The development of a novel label-free graphene sensor array is presented. Detection is based on modification of graphene FET devices and specifically monitoring the change in composition of the nutritive components in culturing medium. Micro-dispensing of Escherichia coli in medium shows feasibility of accurate positioning over each sensor while still allowing cell proliferation. Graphene FET device fabrication, sample dosing, and initial electrical characterisation have been completed and show a promising approach to reducing the sample size and lead time for diagnostic and drug development protocols through a label-free and reusable sensor array fabricated with standard and scalable microfabrication technologies.
