Supercritical Drug Impregnation onto Intraocular Lenses

Supercritical impregnation is an attractive “clean” alternative to conventional soaking into liquid process, using generally organic solvents. Impregnation process can be used for the development of controlled delivery systems that can be applied in pharmaceutical and medical fields. This work focuses on the preparation of controlled drug delivery systems for ophthalmic applications through sup...

Supercritical water impregnation of CuO nanoparticles on silica-support as new catalyst

In our current study, supercritical water impregnation (SCWI) was introduced as a unique catalyst preparation method by employing the high diffusivity property of supercritical water. The method allows nano-particles to place on support surfaces in extremely dispersed conditions. The silica-based nanocatalyst granules for this purpose were prepared by initial impregnation of highly porous silic...

Supercritical Co2 Impregnation of Polyethylene Components for Medical Purposes

Modern hip and knee endoprosthesis are produced in titanium and to reduce the friction at the contact area polymer parts, mainly ultra-high molecular weight polyethylene (UHMW-PE), are installed. The polyethylene is impregnated with αtocopherol (vitamin E) before processing for remarkable decrease of oxidative degradation. Cross linked UHMW-PE offers much higher stability, but α-tocopherol cann...
