Abstract
Albumin particles in the nanometer and micrometer size range in an aqueous suspension are rendered stable against resolubilization without the aid of a crosslinking agent and without denaturation, by the incorporation of hemoglobin in the particle composition. Particles which are primarily hemoglobin in the nanometer and micrometer size range in an aqueous suspension are rendered stable against aggregation by the incorporation of either albumin, surface active agents or gelatin.
