Unlocking the Power of Device-Free Cold Plasma for Tumor Sensitization
Current cancer treatments like chemotherapy and radiation often struggle to target cancer cells without harming healthy tissue. Many tumors—especially aggressive or drug-resistant types—remain difficult to treat due to limited drug penetration, poor selectivity, and systemic toxicity. There is a pressing need for a method that can sensitize...

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...

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...

Chance-Constrained Optimization for Treatment of Prostate and Other Cancers in Intensity-Modulated Proton Therapy
The quality of IMPT treatment plans may be drastically diminished by uncertainties such as proton range and patient setup errors. If these uncertainties are not figured into treatment planning, the dose distribution that the patient receives may not be the same as the planned dose distribution. New treatment plans, which include optimized software/programming,...
