Hypoxia is a characteristic feature of various ischemic diseases, including cancer. This study describes the development of glycol chitosan nanoparticles, hydrophobically modified with 4-nitrobenzyl chloroformate and folic acid (FA), that can specifically release drugs under hypoxic conditions. This hypoxia-responsive glycol
