Research interest

Our group is interested in using various nanomaterials as building blocks for constructing novel functional nano/mesoscale structures, either through chemical synthesis or self-assembly. We focus on developing new synthetic strategies which will allow precise control over the property and functionality of the produced structures, putting emphasis in applications for cell-biological studies. Through the strong collaborative efforts ongoing in iCeMS, we aim to utilize such nano/mesoscale structures for probing and manipulating complex biological systems.

We are currently pursuing the following topics.

1. Gold nanoparticles & nanowires

Due to their strong optical responses and biocompatibility, gold nanoparticles are used in a wide range of biological studies. Through precise control over the particle morphology and surface modification, we aim to design and create gold nanostructures that can be used for applications such as bio-sensing and therapeutics.

2. Graphene-based composites

Graphene, which essentially is a single atomic sheet of carbon atoms, has gained much recent interest due to their high surface area, impressive electrical and mechanical properties, and chemical stability. We aim to utilize these sheets as a substrate for loading functional materials such as biomolecules and nanoparticles, which can then be integrated into the biological system.

3. Self-assembly using Langmuir-Blodgettry

When a large number of nanoparticles are put together, their collective properties are not only determined by the individual components, but also by how they are assembled within the superstructure. Langmuir-Blodgettry is a powerful tool which can be used for studying how these nanoscale building blocks assemble in a two-dimensional surface. While gaining fundamental understanding the self-assembly behaviors of the nanomaterials, we also aim to use this technique for the preparing well-controlled layers of biologically relevant moieties, which can serve as a platform for studying cell growth and proliferation.
