Morphology Characterization of SIF/CHI Microspheres.

Abstract

<p>(<b>A</b>-<b>C</b>). The surface morphology of microspheres prepared from optimized (A) or unoptimized (B) formulation was investigated by stereo-microscope and by fluoroscopy (C) using FITC-labeled chi-tosan. (<b>D</b>). The diameter distribution curve of SIF/CHI microspheres. </p
