Abstract
A glass fiber chemical delivery system including water soluble fiberglass particles containing a chemical composition. The water soluble fiberglass particles may define pores in which the chemical composition is contained or the water soluble fiberglass particles may each define a hollow core containing the chemical composition. As the fiberglass particles dissolve in an aqueous environment, such as within cells of a blood vessel wall or in a reaction vessel, the chemical composition is released.
