Fucoidan-Based Theranostic Nanogel for Enhancing Imaging and Photodynamic Therapy of Cancer

引用

Nano-Micro Letters 2020年第4期12卷 14-28页

作者： Mi hyeon cho Yan Li Pui‑Chi Lo Hyeri Lee Yongdoo choi Division of Translational Science Research InstituteNational Cancer Center323 Ilsan‑roGoyangGyeonggi 10408Republic of Korea Department of Biomedical Sciences City University of Hong KongTat Chee AvenueKowloonHong KongChina

In this study, a fucoidan-based theranostic nanogel(CFN-gel) consisting of a fucoidan backbone, redox-responsive cleavable linker and photosensitizer is developed to achieve acti-vatable near-infrared fluorescence imaging of tumor sites and an enhanced photodynamic therapy(PDT) to induce the com-plete death of cancer cells. A CFN-gel has nanomolar a nity for P-selectin, which is overexpressed on the surface of tumor neovascular endothelial cells as well as many other cancer cells. Therefore, a CFN-gel can enhance tumor accumulation through P-selectin targeting and the enhanced permeation and retention e ect. Moreover, a CFN-gel is non-fluorescent and non-phototoxic upon its systemic administration due to the aggregation-induced self-quenching in its fluorescence and singlet oxygen generation. After internalization into cancer cells and tumor neovascular endothelial cells, its photoactivity is recovered in response to the intracellular redox potential, thereby enabling selective near-infrared fluorescence imaging and an enhanced PDT of tumors. Since a CFN-gel also shows nanomolar a nity for the vascular endothelial growth factor, it also provides a significant anti-tumor e ect in the absence of light treatment in vivo. Our study indicates that a fucoidan-based theranostic nanogel is a new theranostic material for imaging and treating cancer with high e cacy and specificity.

疏浚作业时，以底泥释放为代表的内源污染治理问题变得日益突出，减少疏浚带来的水体二次污染是河湖治理中的重点和难点。本文通过使用数学模型FS3M进行全尺寸数值模拟，从流场、悬沙运动及体积变化的角度研究了能减少水体浑浊产生的抓斗最佳下落操作。数值结果表明，抓斗在自重和机械力的控制下，下降过程中会对周围水体产生较大的扰动，卷起较多的床沙，对周边水体环境造成影响。在作业过程中适当的减缓自身下降速度可以有效的抑制床面附近产生的水流速度，随之也会减少悬沙的产生并抑制其随水流运动而向外部扩散。随着计算模型的不断优化升级，今后还需对抓斗铲沙这一动态行为进行模拟分析，深入研究这一行为对泥沙运动规律的影响。该研究的成果可为环保式疏浚工艺提供一定参考。
