Abstract:
PROBLEM TO BE SOLVED: To provide an effective method for depositing inert polymers and pharmaceutical or biological agents onto a substrate, where the collection process is efficient, the coating produced is conformal, substantially defect-free and uniform, the composition of the coating can be regulated and the morphology and/or secondary structure of the pharmaceutical or biological agents can be controlled.SOLUTION: The method for depositing a coating comprising a polymer and pharmaceutical agent on a substrate includes steps of: discharging at least one pharmaceutical agent in a therapeutically desirable morphology in dry powder form through a first orifice; discharging at least one polymer in dry powder form through a second orifice; depositing the polymer and/or pharmaceutical particles onto the substrate, wherein an electrical potential is maintained between the substrate and the pharmaceutical and/or polymer particles, thereby forming the coating; and sintering the coating under conditions that do not substantially modify the morphology of the pharmaceutical agent.

Abstract:
A method for dry-cleaning articles such as fabrics and clothing in carbon dioxide while concurrently applying a sizing agent to the articles comprises contacting an article to be cleaned with a liquid dry cleaning composition for a time sufficient to clean the fabric. The liquid dry-cleaning composition comprises a mixture of carbon dioxide, a surfactant, a sizing agent. An organic co-solvent is preferably included. After the contacting step, the article is separated from the liquid dry cleaning composition. The method is preferably carried out at ambient temperature. Preferred sizing agents are low molecular weight hydrocarbon resins. The surfactant is preferably one that does not contain a CO2-philic group. The organic co-solvent is preferably an alkane and has a flash point above 140° F.
