  • Template assisted surface micro microstructuring of flowable dental composites and its effect on the microbial adhesion properties 

    Frenzel, Nadja; Maenz, Stefan; Sanz Beltrán, Vanesa; Völpel, Andrea; Sigusch, Bernd W.; Lüdecke, Claudia; Jandt, Klaus D. (Academy of Dental Materials, 2016-03-01)
    Article
    Accés obert
    Despite their various advantages, such as good esthetic properties, absence of mercury and adhesive bonding to teeth, modern dental composites still have some drawbacks, e.g., a relatively high rate of secondary caries on ...
  • In vivo testing of gold nanoparticles using the Caenorhabditis elegans model organism 

    Gonzalez-Moragasa, Laura; Berto, Clara; Vilches, Clara; Quidant, Romain; Kolovouc, Androniki; Santarella-Mellwig, Rachel; Schwab, Yannick; Stürzenbaum, Stephen; Roig, Anna; Laromainea, Anna (Elsevier, 2017-02-01)
    Article
    Accés obert
    Gold nanoparticles (AuNPs) are present in many man-made products and cosmetics, and are also used by the food and medical industries. Tight regulations regarding the use of mammalian animals for product testing can hamper ...
  • Cyclic concentrator, carpet cloaks and fisheye lens via transformation plasmonics 

    Alaoui, M.; Rustomji, K.; Chang, T. M.; Tayeb, G.; Sabouroux, P.; Quidant, R.; Enoch, S.; Guenneau, S.; Abdeddaim, R. (IOP, 2016-04-01)
    Article
    Accés obert
    We first review basic equations of plasmonics in anisotropic media. We recall the origin of Maxwell’s gradient index fisheye lens. We then apply tools of transformation optics to the design of a cyclic concentrator and ...
  • Dynamic Range Extension of a SPAD Imager Using Non-Uniformity Correction Techniques 

    Vilella, Eva; García, José; Alonso, Oscar; Diéguez, Angel (IEEE, 2016-01-27)
    Article
    Accés obert
    The extraordinary sensitivity of single-photon avalanche diodes (SPADs) makes these devices the ideal option for vision systems aimed at low-light applications. Nevertheless, there exist large dark count rate and photon ...
  • Cooling and manipulation of a levitated nanoparticle with an optical fiber trap 

    Mestres, Pau; Berthelot, Johann; Spasenović, Marko; Gieseler, Jan; Novotny, Lukas; Quidant, Romain (AIP, 2015-10-15)
    Article
    Accés obert
    Accurate delivery of small targets in high vacuum is a pivotal task in many branches of science and technology. Beyond the different strategies developed for atoms, proteins, macroscopic clusters, and pellets, the manipulation ...
  • Coupling of individual quantum emitters to channel plasmons 

    Bermúdez-Ureña, Esteban; Gonzalez-Ballestero, Carlos; Geiselmann, Michael; Marty, Renaud; Radko, Ilya P; Holmgaard, Tobias; Alaverdyan, Yury; Moreno, Esteban; García-Vidal, Francisco J. G; Bozhevolnyi, Sergey I.; Quidant, Romain (Nature Publishing Group, 2015-08-07)
    Article
    Accés obert
    Efficient light-matter interaction lies at the heart of many emerging technologies that seek on-chip integration of solid-state photonic systems. Plasmonic waveguides, which guide the radiation in the form of strongly ...
  • Adiabatic Processes Realized with a Trapped Brownian Particle 

    Martínez, Ignacio A.; Roldán, Édgar; Dinis, Luis; Petrov, Dmitri; Rica, Raúl A. (APS Physics, 2015-03-27)
    Article
    Accés obert
    The ability to implement adiabatic processes in the mesoscale is of key importance in the study of artificial or biological micro- and nanoengines. Microadiabatic processes have been elusive to experimental implementation ...
