Development and Optimization of an Ex Vivo Colloidal Stability Model for Nanoformulations.

abstract：:Next to the coating formulation, process conditions play important roles in determining coating quality. This study aims to develop an operational window that separates layering from agglomeration regimes and, furthermore, the one that leads to the best coating quality in a fluidized bed coater. The bed relative humid...
