    Master thesis
    Open Access
    Covenantee:  Universitat Autònoma de Barcelona / Institut de Ciències Fotòniques (ICFO) / Universitat de Barcelona
    In this report we present a technique for imaging the momentum distribution of an ultracold atomic gas in 3D and with single atom resolution. We describe the first experimental steps taken to implement it in a quantum gas ...
  • Development of an image sensor platform for microorganisms in water 

    Sevilla Dalmau, Daniel (Universitat Politècnica de Catalunya, 2018-09-06)
    Master thesis
    Restricted access - confidentiality agreement
    In this thesis, we demonstrate the correct operation of a fluorescence sensor designed for the analysis of water samples, in concrete phytoplankton levels and microorganism counting. The system, based on different techniques ...
  • Disseny i realització d'un sistema de mesura d'oxigen dissolt basat en fluorescència 

    Benedicto Melero, Raquel (Universitat Politècnica de Catalunya, 2016-06)
    Master thesis (pre-Bologna period)
    Open Access
    Design and implementation of a system for measuring oxygen concentration in a bioreactor based on fluorescence. This system uses a sensor that emits fluorescence and the working principle is based on dynamic fluorescence ...
  • Estudio sobre la optimización de la detección del efecto Raman frente a la fluorescencia: aplicación a obras de arte 

    Martí Edo, Albert (Universitat Politècnica de Catalunya, 2011-11-02)
    Master thesis (pre-Bologna period)
    Open Access
    English: Nowadays, Raman spectroscopy has become a very important tool for identifying chemical compounds and their molecular structures since it is non-destructive, has null or near null requirements of sample preparation, ...
  • In-plane plasmonic antenna arrays with surface nanogaps for giant fluorescence enhancement 

    Flauraud, Valentin; Regmi, Raju; Winkler, Pamina Martina; Alexander, Duncan T. L.; Rigneault, Herve; Hulst, Niek F. van; Garcia-Parajo, Maria F.; Wenger, Jerome; Brugger, Juergen (ACS, 2017-02-10)
    Article
    Open Access
    Optical nanoantennas have a great potential for enhancing light-matter interactions at the nanometer scale, yet fabrication accuracy and lack of scalability currently limit ultimate antenna performance and applications. ...
  • Morphology-based automated baseline removal for raman spectra of artistic pigments 

    Pérez Pueyo, Rosanna; Soneira Ferrando, M. José; Ruiz Moreno, Sergio (2010-06)
    Article
    Open Access
    The interpretation of a Raman spectrum is based on the identification of its characteristic molecular bands. However, the assignment of the vibrational modes is often compromised by the presence in the spectrum of an intense ...
  • Multispectral and colour imaging systems for the detection of small vertebrate fossils: A preliminary study 

    Delpueyo Español, Xana; Vilaseca Ricart, Meritxell; Furió, Marc; Burgos Fernández, Francisco J.; Pujol Ramo, Jaume (2016)
    Article

  • Observing the angular radiation patterns of single emitters by Back Focal Plane Imaging 

    Karanikolopoulos, Dimitrios (Universitat Politècnica de Catalunya, 2013-09-09)
    Master thesis
    Open Access
    [ANGLÈS] This study is concerned with the fluorescence of single quantum emitters. The emission patterns of these emitters are affected by their environment. We modify the inhomogeneous environment of single emitters using ...
  • Posada a punt d'un mètode d'anàlisi d'arsènic en lixiviats de minerals i sòls mitjançant fluorescència atòmica 

    Granados Velasco, Ivan (Universitat Politècnica de Catalunya, 2016-01-15)
    Bachelor thesis
    Open Access
    En aquest projecte s’ha posat a punt un mètode d’anàlisi d’As mitjançant fluorescència atòmica. S’han utilitzat mostres sintètiques per a l’obtenció de tots els resultats. Abans de procedir a les etapes d’anàlisi s’ha fet ...
  • Single molecule evaluation of fluorescent protein photoactivation efficiency using an in vivo nanotemplate 

    Durisic, Nela; Laparra-Cuervo, Lara; Sandoval-Álvarez, Ángel; Borbely, Joseph Steven; Lakadamyali, Melike (Nature, 2014-01-05)
    Article
    Open Access
    Photoswitchable fluorescent probes are central to localization-based super-resolution microscopy. Among these probes, fluorescent proteins are appealing because they are genetically encoded. Moreover, the ability to achieve ...
  • Two photon versus one photon fluorescence excitation in whispering gallery mode microresonators 

    Pastells, Carme; Marco, M. Pilar; Merino, David; Loza-Álvarez, Pablo; Pasquardini, Laura; Lorenzo, Lunelli; Pederzolli, Cecilia; Daldosso, Nicola; Farnesi, Daniele; Berneschi, Simone; Righini, Giancarlo C.; Quercioli, Franco; Conti, Gualtiero Nunzi; Soria, Silvia (ScienceDirect, 2016-02-01)
