  • Cell Proliferation Tracking Using Graphene Sensor Arrays 

    DUESBERG, GEORG STEFAN; HEGNER, MARTIN (2012)
    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 ...
  • DMF-exfoliated graphene for electrochemical NADH detection 

    DUESBERG, GEORG STEFAN; KEELEY, GARETH; O'NEILL, ARLENE; COLEMAN, JONATHAN NESBIT (2011)
    The electrochemical detection of NADH is of considerable interest because it is required as a cofactor in a large number of dehydrogenase-based biosensors. However, the presence of oxygenated functionalities on the electrode ...
  • Flexible, Transparent, Conducting Films of Randomly Stacked Graphene from Surfactant-Stabilized, Oxide-Free Graphene Dispersions 

    COLEMAN, JONATHAN NESBIT; DUESBERG, GEORG STEFAN (Wiley-Blackwell, 2010)
    We have exfoliated graphite in water to give dispersions of mono and few-layer graphene stabilised by surfactant. These dispersions can be used to form thin, disordered films of randomly stacked, oxide-free, few-layer ...
  • Functionalisation of graphene surfaces with downstream plasma treatments 

    DUESBERG, GEORG STEFAN; NOLAN, HUGO CONOR; MC EVOY, NIALL; HALLAM, TOBY (2013)
    We report on an adjustable process for the functionalisation of graphene surfaces with a downstream plasma source. The parameters of oxygen plasma treatments are modified such that oxygenated functionalities can be added ...
  • High-Performance Sensors Based on Molybdenum Disulfide Thin Films 

    DUESBERG, GEORG STEFAN; MC EVOY, NIALL; HALLAM, TOBY (2013)
    High-performance sensors based on molybdenum disulfide (MoS2) grown by sulfurization of sputtered molybdenum layers are presented. Using a simple integration scheme, it is found that the electrical conductivity of MoS2 ...
  • High-yield production of graphene by liquid-phase exfoliation of graphite 

    GOUNKO, IOURI; NICOLOSI, VALERIA; GOODHUE, ROBBIE; SCARDACI, VITTORIO; COLEMAN, JONATHAN NESBIT; BOLAND, JOHN; DUESBERG, GEORG STEFAN (2008)
    Graphene is at the centre of nanotechnology research. In order to fully exploit its outstanding properties, a mass production method is necessary. Two main routes are possible: large-scale growth or large-scale exfoliation. ...
  • Highly sensitive, transparent, and flexible gas sensors based on gold nanoparticle decorated carbon nanotubes 

    DUESBERG, GEORG STEFAN; NOLAN, HUGO CONOR; HALLAM, TOBY (2013)
    We report on a high performance flexible and transparent chemical sensor based on functionalised single-walled carbon nanotubes (SWCNTs). The SWCNT films were spray-deposited on transparent and flexible plastic substrates, ...
  • Large magnetoresistance in few layer graphene stacks with current perpendicular to plane geometry 

    DUESBERG, GEORG STEFAN; SHVETS, IGOR; CROSS, GRAHAM; ZHI - MIN, LIAO (2012)
    Large magnetoresistance (MR) effect of few layers graphene between two non-magnetic metal electrodes with current perpendicular to graphene plane was studied. A non-saturation and anisotropic MR with the value over 60% at ...
  • Lateral Size Selection of Surfactant-Stabilised Graphene Flakes using Size Exclusion Chromatography 

    DUESBERG, GEORG STEFAN; COLEMAN, JONATHAN NESBIT; SMITH, RONAN; WIRTZ, CHRISTIAN (2012)
    Aqueous dispersions of graphene, stabilised by a surfactant, have been separated according to lateral flake size using size exclusion chromatography. Transition electron microscopy was used to characterise the flake size ...
  • Magnetoresistance of Fe3O4-graphene-Fe3O4 junctions 

    SHVETS, IGOR; CROSS, GRAHAM; DUESBERG, GEORG STEFAN; WANG, JING JING (2011)
    The magnetoresistance (MR) of Fe3O4-graphene-Fe3O4 junctions has been experimentally studied at different temperatures. It is found that a barrier exists at the Fe3O4/graphene interface. The existence of the interfacial ...
  • Report on the Special Miniworkshop "nano&Management" 

    DUESBERG, GEORG STEFAN (2013)
    This is a short report on a special workshop on matters “around” science, held during the Kirchberg Winterschool 2013 on Electronic Properties of Novel Materials. The topics discussed are patents, experiences of small ...
  • Transparent ultrathin conducting carbon films 

    BOESE, MARKUS; DUESBERG, GEORG STEFAN; LUTZ, TAREK; KUMAR, SHISHIR (2010)
    Ultrathin conductive carbon layers (UCCLs) were created by spin coating resists and subsequently converting them to conductive films by pyrolysis. Homogeneous layers as thin as 3 nm with nearly atomically smooth surfaces ...
