Adaptive optics multiphoton microscopy to study ex vivo ocular tissues
(2010)
Article
Restricted access - publisher's policyWe develop an adaptive optics (AO) multiphoton microscope by incorporating a deformable mirror and a Hartmann-Shack wavefront sensor. The AO module operating in closed-loop is used to correct for the aberrations of the ... -
Analysis of corneal stroma organization with wavefront optimized nonlinear microscopy
(2011-06)
Article
Open AccessTo investigate the organization of stromal collagen in healthy ex vivo corneas of different species from second harmonic generation (SHG) microscopy images -
Análisis de imágenes digitales de células linfoides de sangre periférica a partir de microscopía óptica
(Universitat Politècnica de Catalunya, 2017-01-09)
Bachelor thesis
Open Access
Covenantee: Centre Mèdic TeknonPara poner en contexto este proyecto, se debe saber que los sistemas automáticos que asisten en procesos de diferenciación de células sanguíneas encontrados actualmente en el mercado son caros y funcionan mejor en muestras ... -
Atomic force microscopy-based mechanobiology
(Nature, 2018-11-01)
Article
Open AccessMechanobiology emerges at the crossroads of medicine, biology, biophysics and engineering and describes how the responses of proteins, cells, tissues and organs to mechanical cues contribute to development, differentiation, ... -
Automated corneal endothelium image segmentation in the presence of cornea guttata via convolutional neural networks - 115110H
(International Society for Photo-Optical Instrumentation Engineers (SPIE), 2020)
Conference report
Restricted access - publisher's policyAutomated cell counting in in-vivo specular microscopy images is challenging, especially in situations where single-cell segmentation methods fail due to pathological conditions. This work aims to obtain reliable cell ... -
Cell segmentation and tracking in phase-contrast microscopy data
(Universitat Politècnica de Catalunya, 2020-06)
Bachelor thesis
Open Access
Covenantee: Universitetet i TromsøUnderstanding how cells change and move during a period of time under different conditions is essential to understanding cell migration and its multiple implications in scientific research. But segmenting and tracking ... -
Characterization of the individual response of multimodal upconversion and nonlinear nanoparticles
(Universitat Politècnica de Catalunya, 2020-11-26)
Master thesis

Confocal unrolled areal measurements of cylindrical surfaces
(2017)
Conference report
Restricted access - publisher's policyConfocal microscopes are widely used for areal measurements thanks to its good height resolution and the capability to measure high local slopes. For the measurement of large areas while keeping few nm of system noise, it ... -
Conversion of a polarization microscope into a Mueller matrix microscope. Application to the measurement of textile fibers
(2015)
Article
Restricted access - publisher's policyThis work reports the conversion of a commercial polarization microscope (Zeiss Jenaval) into an automatized Mueller matrix microscope. A Mueller matrix measurement provides the value of all the optical properties of a ... -
Critical assessment of two-dimensional methods for the microstructural characterization of cemented carbides
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-11-03)
Article
Open AccessCemented carbides, or hard metals, are ceramic–metal composites usually consisting of tungsten carbide particles bound by a cobalt-based alloy. They are the backbone materials for the tooling industry, as a direct consequence ... -
Depth aberrations characterization in linear and nonlinear microscopy schemes using a Shack-Hartmann wavefront sensor
(2012)
Conference report
Restricted access - publisher's policyThe performance of imaging devices such as linear and nonlinear microscopes (NLM) can be limited by the optical properties of the imaged sample. Such an important aspect has already been described using theoretical models ... -
Design, implementation and test of a routine Light Sheet fluorescence microscope
(Universitat Politècnica de Catalunya, 2015-06)
Bachelor thesis
Open AccessMicroscopy has revealed an astonishing new world that was previously invisible to our eyes. Unfortunately, we still have very little knowledge of how life actually works, and for that reason new powerful microscopy techniques ... -
