The degradation of cell seeded 3D scaffolds is an important step both for the in vivo and in vitro use of biomimetic matrices mimicking the extracellular matrix. In this respect, we investigated the possibility of enzymatically degrading a chitosan microbeads scaffold supporting a mature 3D neuronal network. To this purpose, the enzymes...

Over 85% of human cancers are solid tumors. The effectiveness of anticancer therapy in solid tumors depends on adequate delivery of the therapeutic agent to tumor cells. Inadequate delivery would result in residual tumor cells, which in turn would lead to regrowth of tumors and possibly development of resistant cells. The most prominent option,...

In this work, the preparation of a novel enzyme carrier based on a polymer multicomponent system was assessed. Indeed, the design of the above system considered several issues that are the need of applying a biodegradable polymer carrier, characterized by a nanometric dimension, thus suitable to diffuse into the dense mucus structure, with...

The process of Ca2+ mediated gelation of alginate and the fabrication of nanoengineered polyelectrolyte capsules were combined for the preparation of alginate microbeads characterized by the presence of well-defined drug loaded microvoids in their volume. The obtained engineered alginate microbeads are described in terms of their morphology,...
