Nanomaterials based strategies for treatment of hypoxic tumor

Hypoxic tumor microenvironment restricts efficiency of tumor therapies and leads to serious results of tumor recurrence and high mortality. Different strategies to treat hypoxic tumors based on nanomaterials have been utilized to eliminate the side effects of hypoxia on tumor therapies. The strategies could be summarized into two classes, i) elevating oxygen level in tumor by nanomaterials and ii) diminishing oxygen dependence of nanomaterials for hypoxic tumor therapy.
