Radiotherapy Enhancement by Gold Nanocluster‐functionalized Nanoliposomes Using Polychromatic Orthovoltage X‐ray Irradiation

open access: yesAdvanced Materials Interfaces, EarlyView.
Lipid drug carriers to which ultra‐small gold nanoparticles were added enabled more efficient radiotherapy of cultured pancreatic cancer tumors. These nanoparticles boosted radiation‐induced damage to tumors by generating more reactive molecules, though higher gold levels are needed for strong benefits.
