Abstract:
Reactive oxygen species (ROS) play a critical role in osteosarcoma (OS) therapy by inducing programmed cell death when their levels exceed the cellular threshold. Due to their inherently elevated ROS levels, OS cells are more susceptible to ROS upregulation than normal bone cells, offering a therapeutic window for selective cancer cell elimination. However, the intrinsic antioxidant defense mechanisms in OS cells mitigate the effects of conventional ROS-generating agents, limiting their clinical efficacy. To overcome this challenge, nanoparticle-based strategies have been developed to enhance ROS production and improve therapeutic outcomes. Despite significant progress, a comprehensive framework for designing and optimizing ROS-generating nanoplatforms for OS treatment remains lacking. This review systematically classifies ROS-upregulating nanoparticles based on their underlying mechanisms of action and discusses their therapeutic potential. Additionally, key challenges and future directions are highlighted to guide the development of next-generation nanomaterials for OS therapy.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
