Recently, School of Perfume and Aroma Technology has made a breakthrough in cigarette flavoring and harm reduction. The first unit of the paper entitled "Highly Biocompatible Composites as Cigarette Smoke Purifiers for Free Radical Scavenging and Pungent Odor Masking" published in the authoritative journal Advanced Functional Materials (Top Journal of Material Science Zone 1, IF=19) in the field of materials is Shanghai Institute of Technology. Professor Hu Jing and Dr. Zhou Lulu of our school are co corresponding authors, and Guo Zining, a postgraduate student of School of Perfume and Aroma Technology, is the first author of the paper.

After cigarette lighting, the smoke will release high levels of reactive oxygen species and reactive nitrogen. Excessive free radicals will mediate the imbalance between the oxidative defense system and the antioxidant defense system, further leading to cell dysfunction and death. Additionally, cigarettes will produce irritating odors during production and processing, affecting the quality of cigarettes. Based on this, the team introduced carbon dot nanoenzymes with free radical scavenging activity and peppermint ketone for improving aroma into a well biocompatible γ - cyclodextrin based metal organic framework, thus developing a new type of smoke purifier (CDs/ ME@MOF) to reduce the odor stimulation in cigarette smoke and reduce the pulmonary toxicity caused by smoke.

This work emphasizes CDs/ME@MOF as a safe, environmentally friendly, and versatile additive with the potential to modify cigarette filters. A new strategy has been proposed to simultaneously reduce damage and irritation, providing excellent value for future cigarette filter modifications that reduce the toxicity of cigarette smoke.
