Antisolvent vapour precipitation of droplets with multi-components: Non-soluble encapsulation and simultaneous precipitation of soluble materials

S Yue, S Mansouri, MW Woo, XD Chen - Chemical Engineering Research …, 2013 - Elsevier
A new antisolvent vapour precipitation technique was developed which enables the
production of a large amount of micro spheres from a single droplet. This work explores the
potential of this technique for encapsulation of oil and in precipitating multi-component
solutes from a droplet. Experiments were undertaken on the single droplet drying rig in
Monash University, modified to incorporate antisolvent vapour. Using ethanol vapour,
lactose micro particles with spiky surfaces were formed. Oil-infused lactose micro particles …
