  • Widefield SERS for High-Throughput Nanoparticle Screening 

    Liebel, Matz; Calderon, Irene; Pazos-Perez, Nicolas; van Hulst, Niek F.; Alvarez-Puebla, Ramon A (Wiley, 2022-02-02)
    Article
    Restricted access - publisher's policy
    Surface-enhanced Raman scattering (SERS) imaging is a powerful technology with unprecedent potential for ultrasensitive chemical analysis. Point-by-point scanning and often excessively long spectral acquisition-times hamper ...

  • Surface-Enhanced Raman Scattering Holography 

    Liebel, Matz; Pazos-Perez, Nicolas; van Hulst, Niek F.; Alvarez-Puebla, A. (nature, 2020-09-15)
    Article
    Open Access
    Nanometric probes based on surface-enhanced Raman scattering (SERS) are promising candidates for all-optical environmental, biological and technological sensing applications with intrinsic quantitative molecular specificity. ...

  • Fast photochronoamperometry of photosynthetic complexes for biosensors and electron transport studies 

    López-Ortiz, Manuel; Zamora, Ricardo A.; Remesh, Vikas; Hu, Chen; Croce, Roberta; van Hulst, Niek F.; Gorostiza, Pau (ACS, 2021-02-16)
    Article
    Open Access
    Photosynthetic reactions in plants, algae, and cyanobacteria are driven by photosystem I and photosystem II complexes, which specifically reduce or oxidize partner redox biomolecules. Photosynthetic complexes can also bind ...

  • Selective excitation of individual nanoantennas by pure spectral phase control in the ultrafast coherent regime 

    Accanto, Nicolò; Roque, Pablo M. de; Galvan-Sosa, Marcial; Hancu, Ion M.; van Hulst, Niek F. (De Gruyer, 2020-09-07)
    Article
    Open Access
    Coherent control is an ingenious tactic to steer a system to a desired optimal state by tailoring the phase of an incident ultrashort laser pulse. A relevant process is the two-photon–induced photoluminescence (TPPL) of ...

  • Phase control of plasmon enhanced two-photon photoluminescence in resonant gold nanoantennas 

    Remesh, Vikas; Stührenberg, Michael; Saemisch, Lisa; Accanto, Nicolò; van Hulst, Niek F. (AIP, 2018-08-08)
    Article
    Open Access
    Plasmonic nanoantennas emit two-photon photoluminescence, which is much stronger than their second harmonic generation. Unfortunately, luminescence is an incoherent process and therefore generally not explored for nanoscale ...

  • Cold and Hot Spots: from Inhibition to Enhancement by Nanoscale Phase Tuning of Optical Nanoantennas 

    Blascetta, Nicola Palombo; Lombardi, Pietro; Toninelli, Costanza; van Hulst, Niek F. (ACS, 2020-08-17)
    Article
    Open Access
    Optical nanoantennas are well-known for the confinement of light into nanoscale hot spots, suitable for emission enhancement and sensing applications. Here, we show how control of the antenna dimensions allows tuning ...

  • Far-field control of nanoscale hotspots by near-field interference 

    Singh, Anshuman; Hugall, James T.; Calbris, Gaëtan; Hulst, Niek F. van (ACS, 2020-07-31)
    Article
    Open Access
    Optical nanoantennas coherently scatter incident optical radiation, creating a localized electromagnetic near-field imprinted with subwavelength phase distribution, rapidly changing in space. The nanostructuring of phase ...

  • Room Temperature Excitation-Emission Spectra of Single LH2 Complexes Show Remarkably Little Variation 

    Gellings, Esther; Cogdell, Richard J.; van Hulst, Niek F. (ACS, 2020-03-06)
    Article
    Open Access
    Excitation spectroscopy gives direct insight into the excited state manifold, energy transfer, transient intermediates, vibrations, and so on. Unfortunately, excitation spectroscopy of single molecules under ambient ...

  • Ultrafast Stimulated Emission Microscopy of Single Nanocrystals 

    Piatkowski, Lukasz; Accanto, Nicolò; Calbris, Gaëtan; Christodoulou, Sotirios; Moreels, Iwan; Hulst, Niek F. van (AAAS, 2019-12-06)
    Article
    Open Access
    Single-molecule detection is a powerful method used to distinguish different species and follow time trajectories within the ensemble average. However, such detection capability requires efficient emitters and is prone to ...

  • Nanoscale Imaging and Control of hexagonal Boron-Nitride Single Photon Emitters by a Resonant Nano-antenna 

    Palombo Blascetta, Nicola; Liebel, Matz; Lu, Xiaobo; Taniguchi, T; Watanabe, K; Efetov, Dmitri K; Hulst, Niek F. van (ACS, 2020-02-13)
    Article
    Open Access
    Defect centers in two-dimensional hexagonal boron nitride (hBN) are drawing attention as single-photon emitters with high photostability at room temperature. With their ultrahigh photon-stability, hBN single-photon emitters ...

  • Control of Vibronic Transition Rates by Resonant Single-Molecule-Nanoantenna Coupling 

    Saemisch, Lisa; Liebel, Matz; Hulst, Niek F. van (ACS, 2020-05-13)
    Article
    Open Access
    Plasmonic nanostructures dramatically alter the radiative and nonradiative properties of single molecules in their vicinity. This coupling-induced change in decay channels selectively enhances specific vibronic transitions, ...

  • Isolating strong nanoantenna-molecule interactions by ensemble-level single-molecule detection 

    Saemisch, Lisa; Liebel, Matz; Hulst, Niek F. van (Royal Society of Chemistry, 2020-01-16)
    Article
    Open Access
    Traditionally, the nanoscale interaction between single photon emitters and plasmonic nanostructures is studied by relying on deterministic, near-perfect, nanoscale-control, either top-down or bottom-up. However, these ...
