  • Bridging quantum and classical plasmonics with a quantum-corrected model 

    Esteban, Ruben; Borisov, Andrei G.; Nordlander, Peter; Aizpurua, Javier (2012)
    Electromagnetic coupling between plasmonic resonances in metallic nanoparticles allows for engineering of the optical response and generation of strong localized near-fields. Classical electrodynamics fails to describe ...
  • Coherent Fano resonances in a plasmonic nanocluster enhance optical four-wave mixing 

    Zhang, Yu; Wen, Fangfang; Zhen, Yu-Rong; Nordlander, Peter; Halas, Naomi J. (2013)
    Plasmonic nanoclusters, an ordered assembly of coupled metallic nanoparticles, support unique spectral features known as Fano resonances due to the coupling between their subradiant and superradiant plasmon modes. Within ...
  • Compact solar autoclave based on steam generation using broadband light-harvesting nanoparticles 

    Neumann, Oara; Feronti, Curtis; Neumann, Albert D.; Dong, Anjie; Schell, Kevin; Lu, Benjamin; Kim, Eric; Quinn, Mary; Thompson, Shea; Grady, Nathaniel; Nordlander, Peter; Oden, Maria; Halas, Naomi J. (2013-07-16)
    The lack of readily available sterilization processes for medicine and dentistry practices in the developing world is a major risk factor for the propagation of disease. Modern medical facilities in the developed world ...
  • Dye-Assisted Gain of Strongly Confined Surface Plasmon Polaritons in Silver Nanowires 

    Paul, Aniruddha; Zhen, Yu-Rong; Wang, Yi; Chang, Wei-Shun; Xia, Younan; Nordlander, Peter; Link, Stephan (2014)
    Subwavelength confinement and active control of light is essential for nanoscale communication devices at visible frequencies that support large bandwidths.[1-5] Noble-metal nanostructures present an excellent platform for ...
  • Evolution of light-induced vapor generation at a liquid-immersed metallic nanoparticle 

    Fang, Zheyu; Zhen, Yu-Rong; Neumann, Oara; Polman, Albert; de Abajo, F. Javier García; Nordlander, Peter; Halas, Naomi J. (2013)
    When an Au nanoparticle in a liquid medium is illuminated with resonant light of sufficient intensity, a nanometer scale envelope of vapor -a “nanobubble”- surrounding the particle, is formed. This is the nanoscale onset ...
  • Impurity-Induced Plasmon Damping in Individual Cobalt-Doped Hollow Au Nanoshells 

    Thibodeaux, Christyn A.; Kulkarni, Vikram; Chang, Wei-Shun; Neumann, Oara; Cao, Yang; Brinson, Bruce; Ayala-Orozco, Ciceron; Chen, Chih-Wei; Morosan, Emilia; Link, Stephan; Nordlander, Peter; Halas, Naomi J. (2014)
    The optical properties of plasmonic nanoparticles in the size range corresponding to the electrostatic, or dipole, limit have the potential to reveal effects otherwise masked by phase retardation. Here we examine the optical ...
  • Nanoparticles Heat through Light Localization 

    Hogan, Nathaniel J.; Urban, Alexander S.; Ayala-Orozco, Ciceron; Pimpinelli, Alberto; Nordlander, Peter; Halas, Naomi J. (2014)
    Aqueous solutions containing light-absorbing nanoparticles have recently been shown to produce steam at high efficiencies upon solar illumination, even when the temperature of the bulk fluid volume remains far below its ...
  • Quantum effects and nonlocality in strongly coupled plasmonic nanowire dimers 

    Teperik, Tatiana V.; Nordlander, Peter; Aizpurua, Javier; Borisov, Andrei G. (2013)
    Using a fully quantum mechanical approach we study the optical response of a strongly coupled metallic nanowire dimer for variable separation widths of the junction between the nanowires. The translational invariance ...
  • Quantum plasmonics: Symmetry-dependent plasmon-molecule coupling and quantized photoconductances 

    Song, Peng; Meng, Sheng; Nordlander, Peter; Gao, Shiwu (2012)
    We investigate photoinduced electron transport through nanoparticle dimers connected by linear and ringlike molecules. The two model junctions exhibit similar absorption but distinct photoconductance. The linear-chain junction ...
  • A single molecule immunoassay by localized surface plasmon resonance 

    Mayer, Kathryn M.; Hao, Feng; Lee, Seunghyun; Nordlander, Peter; Hafner, Jason H. (2010)
  • The Surprising in Vivo Instability of Near-IR-Absorbing Hollow Au-Ag Nanoshells 

    Goodman, Amanda M.; Cao, Yang; Urban, Cordula; Neumann, Oara; Ayala-Orozco, Ciceron; Knight, Mark W.; Joshi, Amit; Nordlander, Peter; Halas, Naomi J. (2014)
    Photothermal ablation based on resonant illumination of near-infrared-absorbing noble metal nanoparticles that have accumulated in tumors is a highly promising cancer therapy, currently in multiple clinical trials. A crucial ...
