A two-step lighting DNA tetrahedral nanoprobe for precise imaging-guided photodynamic therapy of tumors.

Herein, we innovatively propose a mucin 1 and azoreductase dual-responsive DNA tetrahedral nanoprobe for two-step lighting imaging-guided photodynamic therapy of tumors. We hope that this highly specific, responsive and well biocompatible drug delivery system can be effectively used for the performance of cancer therapy in the hypoxia-related biomedical field.
