Preparation of serum albumin microcapsules

Simple coacervation of bovine serum albumin was studied to prepare biodegradable microcapsules. Three types of microcapsules, which differed in shape, were obtained by changing either core size or the bovine serum albumin concentrations of the coacervating systems. Mononuclear microcapsules were prepared by using spherical poly(acrylonitrile) beads as a core material.
