SUMMARY:Application of Functional Nanomaterials in Tumor Therapy
DESCRIPTION:Cancer is one of the most serious diseases that threaten human health. It is very urgent to develop advanced technology for cancer diagnosis and therapy. The traditional cancer therapy methods include operation\, chemotherapy and radiotherapy etc\, which suffer from long treatment period\, drug resistance\, big side effects. The newly developed minimally invasive treatment processes such as photothermal (PTT)/photodynamic (PDT)/sonodynamic (SDT) therapy and immunotherapy show great promise for cancer therapy\, with advantages of good time-space selection\, safe\, low toxicity and minor side effects. \nIn this lecture\, nanomaterials based photothermal and photodynamic therapy\, sonodynamic therapy and immunotherapy will be discussed. For NIR (laser)-triggered PTT and PDT\, we will present metal/semiconductor heterojunction structure to increase photothermal conversion efficacy\, Pd/Cu single-atom nano-enzyme to realize mild temperature PTT and double photosensitisers to improve ROS yield and increase the therapy efficacy in PDT. For sonodynamic therapy (SDT)\, we will discuss the design and optimization strategy of sonosensitizers\, including defect engineering strategy and heterojunctions route. For immunotherapy\, we will present how nanomaterials function in potentiating immune response\, including immunogenic cell death (ICD)\, construction of tumor nanovaccines and pyroptosis adjuvants. \nFinally\, the future challenges for the application of nanomaterials in tumor therapy will be forecasted. \nBiography of the speaker: \nDr. Jun Lin\, Professor\, and the group leader of luminescent and biomedical materials in Changchun Institute of Applied Chemistry\, Chinese Academy of Sciences. His research mainly focuses on luminescent materials for various applications\, including photoluminescence and spectral properties of rare earth ions and perovskite QDs for applications in displays and lightening (especially for white LED)\, as well as multifunctional materials as theragnostic agents for biomedical applications. He won Grade -1 Award for Science and Technology Progress of Jilin Province three times and was selected as a highly cited researcher in materials science and cross-field in 2014-2023. So far\, he has published more than 900 peer-reviewed journal articles with total citations over 70000 and H index of 140; He also gave more than 100 invited lectures in various kinds of conferences.
