New insights into highly effective combination of microwave dynamic and thermal therapies against cancer

Nanowerk.com - 8 января, 2018 - 13:41
Researchers propose novel flexible Mn-doped zirconium metal-organic frameworks nanocubes for highly effective combination of microwave dynamic and thermal therapy against cancer. This is the first report of determining the microwave thermal conversion efficiency, which can be used to evaluate, compare, and predict the microwave sensitivity of different microwave-sensitive agents. More importantly, such Mn-ZrMOF nanocubes generate abundant reactive oxygen species of hydroxyl radicals under microwave irradiation.
