Spray-Congealing and Wet-Sieving as Alternative Processes for Engineering of Inhalation Carrier Particles: Comparison of Surface Properties, Blending and In Vitro Performance
Purpose
Traditionally, α-lactose monohydrate is the carrier of choice in dry powder inhaler (DPI) formulations. Nonetheless, other sugars, such as D-mannitol, have emerged as potential alternatives. Herein, we explored different particle engineering processes to produce D-mannitol carriers for inhaled delivery.

Physico-chemical Modification of Gelatine for the Improvement of 3D Printability of Oxidized Alginate-gelatine Hydrogels Towards Cartilage Tissue Engineering
This work explored 3D bioplotting to mimic the intrinsic hierarchical structure of natural articular cartilage. Alginate dialdehyde-gelatine (ADA-GEL) was used as a hydrogel ink to create hierarchically ordered scaffolds. In comparison to previously reported ADA-GEL compositions, we introduce a…
