梁湛輝博士的納米科學研究贏得「亞洲核心計劃講學獎」

Dr. Ken Leung, Research Assistant Professor of the Department of Chemistry, and Assistant to the Director of the Institute of Creativity at HKBU received the Asian Core Program Lectureship Award at the 3rd New-Phase International Conference of Cutting-Edge Organic Chemistry in Asia held at Nanyang Technological University, Singapore, from 11 to 14 December 2012. Dr. Leung has also been invited to deliver a week-long series of lectures in South Korea next year.

 

The award was in recognition of Dr. Leung’s outstanding plenary lecture “Interfacial Self-Assembly and Theranostic Applications of Organic-Inorganic Hybrid Nanomaterials” delivered at the Conference. Dr. Leung was delighted at receiving the award. He said: “My research team has extensively developed new materials towards targeted drug delivery, tumour imaging and early diagnosis. Gold and iron oxide hybrid nanomaterials were synthesised and further immobilised with stimuli-responsive supramolecules or polymers. Nanoparticle-labelled stem cells were also employed for magnetic resonance imaging (MRI) tracking using an in-vivo model. The MRI analysis of the superparamagnetic nanomaterials reveals high relaxivities (contrast). These nanomaterials are thus useful nanotheranostic agents.”

 

Nanomaterials are useful in electronic and biomedical applications. In particular, nanotheranostic materials have been involved in the use of nanoparticles for simultaneous diagnostic and therapeutic purposes. The uptake of the nanomaterials by glioblastoma and stem cells is highly efficacious compared to the uptake of normal fibroblast cells. The uptake of anti-cancer drug-loaded nanoparticles by glioblastoma cells has been successful and drugs have been delivered to trigger cell death.

 

Dr. Leung’s research has been focusing on nanoscience which involves the synthesis and supramolecular chemistry of nanoparticles, molecular sensors and molecular machines for electronic and biomedical applications.

 

The Asian Core Program aims at promoting innovative research areas in Asia by organising conferences. The awards are presented to young scientists who show promise in their field.



化學系研究助理教授兼創意研究院院長助理梁湛輝博士剛於二零一二年十二月十一至十四日在新加坡南洋理工大學舉行的「第三屆新階段亞洲尖端有機化學國際會議」上獲頒「亞洲核心計劃講學獎」。此外,梁博士亦應邀在來年前往韓國講學一星期。

 

梁博士在研討會上發表題為「有機—無機雜化納米材料的界面自組裝、臨床診斷和治療的應用」的大會報告。梁博士對研究成果表示高興,他說﹕「我和研究小組合成出一系列新型磁性氧化鐵和黃金雜化納米材料,有助運載抗癌藥到腦腫瘤細胞,並能作為腦腫瘤細胞和幹細胞臨床核磁共振成像診斷造影劑。」

 

納米技術可準確地探測人體內未發病或接近發病的突變細胞(如癌細胞)數目,新型納米載藥器則把藥物準確地運到體內的癌細胞上。相比傳統的放射性和化學治療會把健康細胞一併殺掉,此技術相信會是醫學發展的一個新方向。

 

多年來,梁博士在納米科學方面成就卓越,研究包括以有機合成化學和超分子化學方法,製造新型納米粒子(nanoparticles)、分子傳感器 (molecular sensors) 和分子機器 (molecular machines)。這些分子納米材料不論在電子、化學、醫學和生物科技方面,都有很大的潛在應用價值。

 

亞洲核心計劃旨在透過舉辦研討會,促進亞洲區的學術交流,並頒發講學獎予年輕科學家,表揚他們的傑出研究。
