Development of an electronic aerosol atomisation system for generating three-dimensional (3D) cells in microencapsulations and microtissues characterisation
… motor controller circuits. The microcapsules and 3D microtissues were biophysically characterised. For the output of the system, the microcapsules size slightly increased with the extrusion rates and decreased significantly with the airflow rates. At an extrusion rate of 20 μl/min and airflow rate …
