Targeted suppression of glioma by ultralow-dose x-ray-induced photodynamic therapy and gold-based nanoclusters in preclinical models.

The diffuse and infiltrative nature of high-grade gliomas poses ongoing challenges in treatment and management. Radiotherapy is an important glioma treatment, with a standard radiotherapy dose of 60 gray. However, high-dose radiotherapy is associated with radiation-induced side effects on normal tissue.

Nanosensitizer-mediated unique dynamic therapy tactics for effective inhibition of deep tumors.

X-ray and ultrasound waves are widely employed for diagnostic and therapeutic purposes in clinic. Recently, they have been demonstrated to be ideal excitation sources that activate sensitizers for the dynamic therapy of deep-seated tumors due to their excellent tissue penetration. Here, we focused on the recent progress in five years in the unique dynamic therapy strategies for the effective inhibition of deep tumors that activated by X-ray and ultrasound waves.

Fe-Coordinated Carbon Nanozyme Dots as Peroxidase-Like Nanozymes and Magnetic Resonance Imaging Contrast Agents.

The catalytic activities of currently developed peroxidase-mimic nanozymes are generally limited. Therefore, further efforts are still needed to improve the catalytic performance of peroxidase nanozymes. Herein, we synthesized Fe-coordinated carbon nanozyme dots (Fe-CDs) that can serve as both efficient peroxidase nanozymes and -magnetic resonance imaging (MRI) contrast agents.
