DEM Participation in the 21st LURN Conference

Professor Héctor Sanz presented, at the 21st Lund Respiratory Network Conference, his work entitled "From Sputum Color to Sputum Mechanics: a Biophysical Perspective on Bronchiectasis". This work, which reports the results published in two scientific letters in Archivos de Bronconeumología (Top 6 in its field), addresses from a mechanical engineering perspective the rheological characterisation of sputum in bronchiectasis, demonstrating that macroscopic colour correlates with quantifiable physical parameters (mainly the elastic modulus (G’) and solid content), establishing a direct relationship between composition, viscoelastic behaviour (shear-thinning) and material functionality, and proposing a biophysical mapping (% solids–G’) that allows the definition of sputum mechanical domains with potential application as an objective biomarker to optimise mucociliary transport processes, design therapeutic strategies, and monitor treatment response from an engineering-driven approach.
