“Theranostic” Nanostructures: Diagnostic Imaging & Targeted Therapeutics


Research 5

Given the similarity of size scale of nanostructures, there are exciting opportunities to interrogate and interact physical and hybrid nanostructures with biological structures, ranging from DNAs, Proteins, cells and sub-cellular organelles. Our approach is focused on synthesis of physical and hybrid nanostructures anchored by biological recognition units (e.g., antibodies) to target specific molecular and cell markers.

We use magnetic nanostructures (MNS) for contrast enhancement in magnetic resonance imaging (MRI), and targeted therapeutics facilitated by thermal activation by external RF field. Our current focus is on cancer, cardiovascular and Alzheimer’s disease (AD) via targeting the responsible cells and/or markers. We collaborate and interact with biomedicine and clinical faculty across NU campus, NTU (Singapore) as well as local area hospitals (ENH, NMH,CMRC) for advancing medicine through materials research. Here are some projects currently going on in the lab.
