  • High resolution imaging using nanoparticle based probes 

    Scarpettini, Alberto; Bragas, Andrea (2018)
    New plasmonic probes, based on silica microspheres decorated with metal nanoparticles (Figure 1), are built and used to confine and enhance the electric field in their interaction with the sample, giving ultra-high optical ...
  • Nanorod-based plasmonic substrates with predefined optical resonances 

    Scarpettini, Alberto; Gutierrez, Marina (2018)
    To design and fabricate plasmonic substrates to be used in ultrasensitive chemical sensing or surfaceenhanced spectroscopies, it is important to achieve control on the morphology, dimensions and surface density of metallic ...
