Functional Surfaces Programme

Introduction

Surfaces and interfaces are critical components of advanced functional materials and devices. Smart chemically and topographically engineered surfaces offer precise control over dynamic surface interactions that allow for anti-fouling, self-cleaning, anti-fog, anti-ice, and superwetting (superhydrophobicity/oleophobicity) phenomena amongst others. Soft (dynamic) surface interactions are also crucial to materials exposed to fluid media as in the case of biomedical technologies, where surfaces of medical or diagnostic devices interact with body fluids containing proteins, cells, bacteria or viruses. Our lab investigates complex dynamic surface interactions and specializes in the use of smart soft materials to create responsive biomimetic surfaces that can provide customised interaction with fluids, cells and biological media. This paves the way for next generation materials that can adapt to changing (wet) environments.


Objectives

  • Development of top down & bottom up approaches to surface modification: nano- micro- fabrication, topographical patterning, self-assembly and surface chemical modification and 

  • In depth understanding of coupled chemical and topographical surface engineering effects on dynamic surface interactions with water, oils, (bio)molecules, particles, cells, bacteria  and other relevant species found in operating environments.

 

Applications

  • Superhydrophobicity
  • Anti-fouling
  • Smart responsive surfaces
  • Custom cell culture/cell screening plates
  • Microfluidic devices
  • Modulus tuneable materials
  • Hydrogels
  • Bio-active surfaces
