crospheres/Nanospheres and Encapsulating The- rapeutic Proteins Therein,” granted May 04, 2010. This invention is an improved process to formulate polymeric microspheres and nanospheres, and encapsulate therapeutic proteins or other useful sub- stances, and a polymer microspheres/nanospheres apparatus. This invention also entails methods of purifying protein-containing polymeric microspheres/ nanospheres from unused polymer and an apparatus therefore.
A
In the process, a biodegradable polymer such as PLGA is dissolved in SuperFluids™ and mixed with the target therapeutic in solution or as a slurry of nanoparticles at operating pressures. The mixture is then decompressed through a nozzle into an aqueous solution, liquid nitrogen or an empty ves- sel (spray dryer). Polymer nanospheres are formed encapsulating the protein therapeutics. Alternatively, the polymer-enriched SuperFluids™ stream can be decompressed into an aqueous solution containing the target therapeutic agent. In addition to reduction or elimination of organic solvent usage, use of Super- Fluids™ for making nanospheres imparts advantages of no residual toxic organic solvent and pathogen safety.
phios Corporation was awarded United States Patent No. 7,708,915 B2 for “Polymer Mi-
SuperFluids™ polymer nanospheres (PNS) process can be utilized to encapsulate therapeutic proteins and other molecules without utilizing organic sol- vents as is traditionally done.

(ALD) system timed with the start of the American Vacuum Society’s annual Atomic Layer Depositi- on Meeting in Seoul, Korea where Dr. Philippe de Rouffignac, Arradiance Principal Material Scientist,
A
has been invited to speak on the topic, “ALD of SnO2 as the active component of a Plastic Microchannel- Based Direct Fast Neutron Detector.” The GEMStar, for which Arradiance has already received multiple orders from leading research centers, can be used to deposit thin layers of material on virtually any sub- strate and was designed with the most challenging high aspect ratio and through-pore deposition appli- cations in mind.
rradiance announced their powerful new GEM- Star™ Benchtop Atomic Layer Deposition

The GEMStar system packs the capability to process 6” wafers or solids up to 1” deep along with room for up to 8 precursors in a tiny 31”x 24” x 11” package without sacrificing maintainability or film quality. The system also features a port for optional in-situ me-
