Nanostructured materials – Small particles to solve big problems


Headed by Associate Professor Yi Sun

Small is beautiful! Nanomaterials are not simply materials at ever smaller dimensions; rather, they enable us to utilize the unique physical, chemical, mechanical, and optical properties that naturally occur at that scale. Moreover, by manipulation of matter at the nanoscale, new materials with unusual property combinations can be constructed. In the last decade, nanostructured materials are considered as revolutionary solutions to solve challenges in diagnostics, therapies, water purification, energy production, food security, environmental monitoring and remediation.

We believe that the huge potential of nanomaterials has only just begun to be tapped. This fascinating research field provides endless possibilities, and new knowledge and exciting applications are waiting just around the corner. Following this vision, the research at Nanomaterials and Nanobiosensors group focuses on the following areas.

  • Design, synthesis and characterization of cutting-edge nanomaterials with novel structures and functionalities:

    - Smart nanomaterials: developing new multi-functional nanocomposites with combined magnetic, optical, molecular recognition and stimuli-responsive properties.
    - Microfluidic synthesis: developing microfluidic systems to synthesize nanomaterials in a well-controlled, reproducible and high-throughput manner.


  • New applications of nanomaterials in biosensing, life sciences and medicine:

    - Nanobiosensor: Using nanomaterials in biosensors to enhance the sensitivity and multiplexing capability for detection of toxins and pathogens in food, environmental and clinical samples.
    - Nanomedicine: Studying the biophysicochemical interactions at the nano–bio interface, and exploring the possibilities of using nanomaterials as new drugs or drug carriers.
