    This roadmap, through the contributions of ten groups worldwide, contains different techniques, methods and materials devoted to sensing in nanomedicine. Optics is used in different ways in the detection schemes. Raman, ...
  • Multicolour single molecule emission and excitation spectroscopy reveals extensive spectral shifts 

    Piatkowski, Lukasz; Gellings, Esther; Hulst, Niek F. van (The Royal Society of Chemistry, 2015-07-16)
    Article
    Accés obert
    We explore the distribution and shape of single molecule spectra at room temperature, when embedded in a polymer host. Multicolour excitation and emission spectroscopy is implemented to capture the full inhomogeneous ...
  • Propagation and localization of quantum dot emission along a gap-plasmonic transmission line 

    Castro-Lopez, M.; Manjavacas, A.; García de Abajo, Francisco Javier; Hulst, Niek F. van (OSA, 2015-11-02)
    Article
    Accés obert
    Plasmonic transmission lines have great potential to serve as direct interconnects between nanoscale light spots. The guiding of gap plasmons in the slot between adjacent nanowire pairs provides improved propagation of ...

    Mics, Zoltan; Tielrooij, Klaas-Jan; Parvez, Khaled; Jensen, Søren A.; Ivanov, Ivan; Feng, Xinliang; Müllen, Klaus; Bonn, Mischa; Turchinovich, Dmitry (Nature Publishing Group, 2015-07-16)
    Accés obert
    The outstanding charge transport properties of graphene enable numerous electronic applications of this remarkable material, many of which are expected to operate at ultrahigh speeds. In the regime of ultrafast, sub-picosecond ...
  • Nanoplasmonics: Concluding remarks 

    Hulst, Niek F. van (Royal Society of Chemistry, 2015-04-30)
    Article
    Accés obert
    Faraday Discussions have a splendid reputation in stimulating scientic debates along the traditions set by Michael Faraday himself. The Faraday Discussion 178 on nanoplasmonics has been particularly appropriate. ...
  • Percolating plasmonic networks for light emission control 

    Gaio, Michele; Castro-Lopez, Marta; Renger, Jan; Hulst, Niek van; Sapienza, Riccardo (Royal Society of Chemistry, 2014-10-15)
    Article
    Accés obert
    Optical nanoantennas have revolutionised the way we manipulate single photons emitted by individual light sources in a nanostructured photonic environment. Complex plasmonic architectures allow for multiscale light control ...
  • Hot-carrier photocurrent effects at graphene–metal interfaces 

    Tielrooij, K. J.; Massicotte, M.; Piatkowski, L.; Woessner, A.; Ma, Q.; Jarillo-Herrero, P.; Hulst, N. F. van; Koppens, F. H. L. (IOP, 2015-03-02)
    Article
    Accés obert
    Photoexcitation of graphene leads to an interesting sequence of phenomena, some of which can be exploited in optoelectronic devices based on graphene. In particular, the efficient and ultrafast generation of an electron ...
  • Generation of photovoltage in graphene on a femtosecond timescale through efficient carrier heating 

    Tielrooij, K. J.; Piatkowski, L.; Massicotte, M.; Woessner, A.; Ma, Q.; Lee, Y.; Myhro, K. S.; Lau, C. N.; Jarillo-Herrero, P.; Hulst, N. F. van; Koppens, F. H. L. (Nature, 2015-04-13)
    Article
    Accés obert
    Graphene is a promising material for ultrafast and broadband photodetection. Earlier studies have addressed the general operation of graphene-based photothermoelectric devices and the switching speed, which is limited by ...
  • Nanoantenna enhanced emission of light-harvesting complex 2: the role of resonance, polarization, and radiative and non-radiative rates 

    Wientjes, Emilie; Renger, Jan; Curto, Alberto; Cogdell, Richard; Hulst, Niek F. van (Royal Society of Chemistry, 2014-10-03)
    Article
    Accés obert
    Nanoantennae show potential for photosynthesis research for two reasons; first by spatially confining light for experiments which require high spatial resolution, and second by enhancing the photon emission of single ...
