      Azizian, Pooya; Casals Terré, Jasmina; Guerrero-SanVicente, Elena; Grinyte, Ruta; Ricart Campos, Jordi; Cabot, Joan Marc (Multidisciplinary Digital Publishing Institute (MDPI), 2023-08-01)
      Article
      Open Access
      Microfluidics has emerged as a versatile technology that is applied to enhance the performance of analytical techniques, among others. Pursuing this, we present a capillary-driven microfluidic device that improves the ...

    • Quantum-inspired protocol for measuring the degree of similarity between spatial shapes 

      Urrego González, Daniel Fernando; Pérez Torres, Juan (2022-11)
      Article
      Open Access
      We put forward and demonstrate experimentally a quantum-inspired protocol that allows us to quantify the degree of similarity between two spatial shapes embedded in two optical beams without the need to measure the amplitude ...
