## Abstract Blend microspheres of chitosan (CS) with poly(vinyl alcohol) (PVA) were prepared as candidates for oral delivery system. CS/PVA microspheres containing salicylic acid (SA), as a model drug, were obtained using the coacervationβphase separation method, induced by addition of a nonsolvent
## Abstract With bovine serum albumin (BSA) as a model drug, drugβloaded films of chitosan (CS) and poly(vinyl alcohol) (PVA) were obtained by a casting/solvent evaporation method and crosslinked by tripolyphosphate (TPP). The films were characterized by FTIR, XRD, and SEM. The influential factors
