On-demand manipulation of tumorigenic microenvironments by nano-modulator for synergistic tumor therapy

Proper manipulation of tumorigenic microenvironments has been considered as one of the most effective approaches for tumor therapy, which is still a challenge to be well performed. Herein, a nano-modulator was fabricated to manipulate the hypoxia, glucose, radicals and local temperature in tumor tissue as needed, which consists of hemoglobin (Hb) and ferric ion (Fe3+) co-conjugated polydopamine (PDA) as core, glucose oxidase (GOD) as shell, and...
