Abstract / 摘要

Title: Aggregation-Induced Emission: Materials and Biomedical Applications

The recent years have witnessed the fast grow of fluorogens with aggregation-induced emission characteristics (AIEgens) in biomedical research. The weak emission of AIEgens as molecular species and their bright luminescence as nanoscopic aggregates distinguish them from conventional organic luminophores and inorganic nanoparticles, making them wonderful candidates for many high-tech applications. In this talk, we summarize our recent AIE work in the development of new fluorescent bioprobes for biosensing and imaging. The simple design and fluorescence turn-on feature of the molecular AIE bioprobes offer direct visualization of specific analytes and biological processes in aqueous media with higher sensitivity and better accuracy than traditional fluorescence turn-off probes. The AIE dot probes with different formulations and surface functionalities show advanced features over quantum dots and small molecule dyes in noninvasive cancer cell detection, long term cell tracing, and vascular imaging. In addition, our recent discovery that AIEgens with high brightness and efficient reactive oxygen species generation in aggregate state further expanded their applications to image-guided cancer surgery and therapy. Recently, we combined accurate prediction of material performance via first-principle calculations and Bayesian optimization-based active learning to realize a self-improving discovery system for high-performance photosensitizers, which can significantly accelerate the materials innovation for biomedical research. 

題目:聚集誘導發光:材料及生物醫學應用

近年具聚集誘導發光特性的螢光素(AIEgens)在生物醫學研究上發展迅速。聚集誘導發光特性螢光素作為具弱發射性的分子物種及作為具亮發光性的奈米級聚集體,讓它們可以由一般的有機發光團及非有機奈米粒子中分辨出來,使它們適合使用在許多高科技應用中。

在這次講座中,劉博士會講述她及其團隊近期的聚集誘導發光的研究,開發新的螢光生物探針用於在生物感測及成像。這種的生物探計比傳統的有更高的敏銳度及更為準確,並在非入侵性癌細胞偵測、長期的細胞追蹤及血管成像有更好效果。在此之外,更發現一種具有高亮度及高效活性氧的聚集誘導發光特性螢光素可以擴充其應用範疇至癌症圖像引導手術及治療。

最近,劉博士及其團隊通過第一原理計算及貝葉斯優化主動學習,並結合對材料特質的準確預測,實現在高效能光敏劑中的可自我提升的發現系統,可以明顯地加速生物醫學研究上的材料革新。
