Microengineered alveolar array lung-on-chip with hydrogel membrane and simulated breathing mechanics for anti-fibrotic testing

 Biofabrication Tobias A Weber, Pauline Zamprogno, Sabine Schneider, Mohammad Amin Hajari, Philippe Büchler, Nina Hobi, Thomas Geiser, Arunima Sengupta and Olivier T Guenat Abstract We present a precision-engineered lung-on-chip platform that replicates the biomechanical and structural features of the human alveolar microenvironment for respiratory disease modeling and therapeutic evaluation. At the core of the device is a thin, suspended hydrogel membrane composed of biologically
