Abstract CRISPR/Cas9‐based gene therapy and photodynamic both show promise for cancer treatment but still have their drawbacks limited by tumor microenvironment long duration. Herein, CRISPR/Cas9 genome editing strategy a synergistic anti‐tumor therapeutic modality is merged. Chlorophyll (Chl) extracted from natural green vegetables encapsulated in Pluronic F127 (F127) micelles Histidine‐tagged Cas9 can be effectively chelated onto via metal coordination simple incubation, affording Cas9‐Chl@F127 micelles. Mg 2+ acts as an enzyme cofactor to correlatively enhance gene‐editing activity. Upon laser irradiation, Chl effective photosensitizer generates reactive oxygen species (ROS) kill cells. Meanwhile, CRISPR/Cas9, mediated dual deliberately designed gRNAs of APE1 NRF2, reprogram the increasing intracellular accumulation impairing oxidative defense system responsively release presence abundant ATP or low pH In murine model, complexed with including NRF2 significantly inhibits growth. Taken together, micelles, representing first Chl‐based biomaterial delivery Cas9, great PDT editing.

Nanocatalytic medicine is one of the most recent advances in development nanomedicine, which catalyzes intratumoral chemical reactions to produce toxins such as reactive oxygen species situ for cancer specific treatment by using exogenous-delivered catalysts Fenton agents. However, overexpression reductive glutathione and Cu-Zn superoxide dismutase cells will significantly counteract therapeutic efficacy species-mediated oxidative damages. Additionally, direct delivery iron-based agents may arouse undesired detrimental effects anaphylactic reactions. In this study, instead exogenously delivering agents, endogenous copper ions from intracellular have been employed source Fenton-like chelating Cu a common metal ion chelator, N,N,N',N'-tetrakis(2-pyridinylmethyl)-1,2-ethanediamine (TPEN), followed TPEN-Cu(II) chelate reduction TPEN-Cu(I) glutathione.
