Abstract: Methods, devices and arrays for measuring a change in zeta-potential of a surface indicative of a binding event are provided. Pharmacologically active compounds and delivery systems for active pharmaceutical ingredients determined to be pharmacologically active or optimized for pharmacological activity or determined to be useful for delivery of the active pharmaceutical ingredient to a target via measurement of a change in zeta-potential of the compound, ingredient or delivery system are also provided.

Abstract: Aerosols containing a plurality of aqueous droplets, each droplet containing on average at least one essentially-neutral particle sized to fit within the droplet are provided. Aerosols wherein an active pharmaceutical ingredient is attached to, or otherwise incorporated in the essentially neutral particles are also provided. Methods for administering an active pharmaceutical ingredient to a subject in need thereof via inhalation of these aerosols, preferably via nebulizer, are also provided.

Abstract: Novel powders or particles are formed by associating them with relatively small proportions of hydrolysable liquid material. The resulting particle/liquid mass is placed in a mold and sintered under conditions of heat and pressure that enables at least some of the hydrolysable liquid to react within the sintered mass. The sintered mass displays a controllable range of properties such as increased density, increased tensile strength, and improved natural polish finish. The hydrolysable liquid may partially hydrolyze and/or react with the powders and particles, but the liquid is not completely (not 100%) reduced to an inorganic oxide prior to introduction to the mold and performance of the sintering process.
