Claim Text:
1. A composition of fine particles of a poorly water soluble medicinal compound comprising: a liquid; and a plurality of fine particles of said medicinal compound dispersed in said liquid, said fine particles comprising an amorphous solid, said fine particles having an average particle diameter of from 1 to 5000 nanometers, and at least 50% of said particles having a plurality of nano-structures each having a size of 200 nm or less and selected from the group consisting of a bump, a dent, a pore, and mixtures thereof, wherein said fine particles are produced from a poorly water soluble bulk material of said medicinal compound by pulsed-laser-ablation processing of said bulk material and wherein said fine particles retain the chemical composition of said bulk material, and said fine particles are characterized by an x-ray diffraction pattern exhibiting a smooth background having no Bragg peaks representative of a crystalline structure.
