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.
