Magnetically Enhanced Plasma Treatment of Cancer
Previously, GW researchers invented a method to selectively kill cancer cells with cold atmospheric plasma (CAP), while leaving neighboring normal cells unaffected. In the present invention, the researchers devised an enhanced method for CAP cancer therapy by concurrently exposing the cancer cells to a static magnetic field (Fig. 1). The researchers...

Non-Invasive Plasma Discharge Tube Device for Treating Brain Tumors
Treating brain tumors, like glioblastoma, is challenging. Current glioblastoma drugs, Rapamycin and Temozolomide (TMZ), generally only extend life for a matter of months, are not very effective in treating recurring tumors, and have significant clinical toxicity. A novel Plasma Discharge Tube (PDT) device has the potential to be more effective and less...

Cold atmospheric plasma-stimulated media for treating cancers
For successful cancer therapy, the most important aspect is selective eradication of cancer cells without damaging healthy cells. Cancer cells and normal cells have different thresholds for tolerance of reactive oxygen species (ROS) and reactive nitrogen species (RNS) before cell death (apoptosis) is induced. Previously, GW researchers invented a cold...

Optimization of Cold Atmospheric Plasma-Stimulated Media for Treatment of Cancer
Previously, GW researchers invented a method to selectively kill cancer cells with cold atmospheric plasma (CAP) while leaving neighboring normal cells intact. In a subsequent study, the researchers showed that similar anti-cancer effects can be achieved indirectly using CAP-stimulated media (CAPSM). Stability of CAPSM (preservation of its anti-cancer...
