It is the challenging goal in cancer biomedicine to search novel cancer-therapeutic modality with concurrent high therapeutic efficiency on combating cancer and low side effects to normal cells/tissues. The recently developed nanocatalytic cancer therapy based on catalytic Fenton reaction represents one of the promising paradigms for potential clinical translation, which has got fast progress very recently. This progress report discusses the rational design and fabrication of Fenton reaction-based nanocatalysts for triggering the in-situ Fenton chemical reaction within tumor microenvironment to generate highly toxic hydroxyl radicals (•OH), which is highly efficient for killing the cancer cells and suppressing the tumor growth. Several strategies for optimizing the nanocatalytic cancer-therapeutic efficiency of Fenton reaction have been highlighted, including screening high-performance Fenton nanocatalysts, increasing peroxide-hydrogen amounts as the reactants, changing the Fenton-reaction conditions (e.g., temperature, acidity and photo-triggering), and Fenton reaction-based synergistic cancer therapy such as some sequential nanocatalytic reactions with improved therapeutic outcome. The facing challenges and future developments of Fenton reaction-based nanocatalytic cancer therapy are also discussed for further promoting the clinical translation of this emerging cancer-therapeutic modality to benefit the cancer patients.

纳米催化剂增强的Fenton化学反应用于纳米催化肿瘤治疗。

寻找新型的癌症治疗方法,同时具有很高的抗癌治疗效率和对正常细胞/组织的低副作用,是癌症生物医学中具有挑战性的目标。最近开发的基于催化Fenton反应的纳米催化癌症疗法代表了潜在的临床翻译的有希望的范例之一,其近来已取得了快速的进展。本进展报告讨论了基于Fenton反应的纳米催化剂的合理设计和制备,该催化剂可触发肿瘤微环境中的原位Fenton化学反应产生高毒性的羟基自由基(•OH),可高效杀死癌细胞并抑制肿瘤的发生。肿瘤生长。重点介绍了几种优化Fenton反应的纳米催化癌症治疗效率的策略,包括筛选高性能Fenton纳米催化剂,增加作为反应物的过氧化氢量,改变Fenton反应条件(例如温度,酸度和光触发)。 )和基于Fenton反应的协同癌症治疗,例如一些顺序的纳米催化反应,具有改善的治疗效果。还讨论了基于Fenton反应的纳米催化癌症疗法面临的挑战和未来的发展,以进一步促进这种新兴的癌症治疗方式的临床翻译,以使癌症患者受益。改变Fenton反应条件(例如,温度,酸度和光触发),以及基于Fenton反应的协同癌症治疗,例如一些具有改善治疗效果的顺序纳米催化反应。还讨论了基于Fenton反应的纳米催化癌症疗法面临的挑战和未来的发展,以进一步促进这种新兴的癌症治疗方式的临床翻译,以使癌症患者受益。改变Fenton反应条件(例如,温度,酸度和光触发),以及基于Fenton反应的协同癌症治疗,例如一些具有改善治疗效果的顺序纳米催化反应。还讨论了基于Fenton反应的纳米催化癌症疗法面临的挑战和未来的发展,以进一步促进这种新兴的癌症治疗方式的临床翻译,以使癌症患者受益。
