Abstract: Aqueous dispersions of chemically and physically stable particles for use in delivery of active pharmaceutical ingredients and processes for their production and use to enhance a biological response to an active pharmaceutical ingredient and prophylactically or therapeutically treat a subject are provided. Vaccines, wherein the active pharmaceutical ingredient is a solution of subunit vaccine antigen mixed with a colloidal dispersion of electrically charged particles and use of such vaccines in immunization are also provided.

Abstract: Delivery devices of a degradable or nondegradable biocompatible matrix with one or more encapsulated active pharmaceutical ingredients or one or more particle-bound active pharmaceutical ingredients dispersed in the matrix are provided. Also provided are methods for delivering an active pharmaceutical ingredient to a subject with these delivery devices. Modified vaginal rings are also provided as well as surface coatings for delivery devices which minimize bio-interaction of the coated delivery devices.

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: 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.

Abstract: A compact and integrated portable device is provided for the analysis of dispersions by low-field pulsed NMR including: an NMR probe module, a means for generating radio frequency and magnetic field gradient pulses, a signal processor, and a master controller. Also provided are methods for using the device to measure one or more characteristics of phases or particles comprising a dispersion such as surface area, solid/liquid ratio, particle size, and elemental analysis.

Abstract: An apparatus for adsorbing at least one dissolved or suspended constituent from an ionically conducting medium which comprises a cell chamber, fluid inlet and outlet pipes leading into and out of the chamber and, positioned consecutively across the chamber, a charcoal cloth working electrode, a porous plastic, preferably nylon, diaphragm and a graphite or platinum counter electrode. The charcoal cloth working electrode is in intimate electrical contact with a metal wire or gauze and by varying the potential of the wire or gauze with a potentiostat the potential applied to the working electrode can also be varied, preferably by increments of above 0.01 v. Current is supplied to the working electrode by the counter electrode. The porous diaphragm allows the passage of ions from the counter to the working electrode but prevents the passage of particles of charcoal cloth from one electrode to the other.
