Tumor hypoxia is a characteristic hallmark of malignant solid tumors, which remains an essential impediment to many current treatments like chemotherapy, radiotherapy, photodynamic therapy and immunotherapy, thereby leading to poor clinical prognosis after therapy. Rationally, modulating tumor hypoxia can be of great interest to augment the therapeutic efficacy of these treatments. In this review, we focus our discussion on current advances in nanoparticles-mediated tumor reoxygenation strategy for relieving tumor hypoxia to improve the therapeutic efficacy of versatile therapies. These nanoparticles can improve tumor oxygen levels via nanoparticles-mediated oxygen-carrying or oxygen-generating tactics to synergize the effectiveness of many current therapeutic modalities. Based on these considerable summaries and analyses, we propose some feasible perspectives on nanoparticles-based tumor reoxygenations to ameliorate the therapeutic outcomes.
