All nanostructured surfaces have unique surface roughness which mathematically describes by the surface architecture or the geometry. Moreover, the nanostructured surfaces may have variable water contact angle values due to the combination of surface roughness and surface composition. The correlation of surface roughness and wettability of nanostructured surfaces to the antibacterial activity becomes significant in designing a numerical model for biomedical devices.

Research activities

The specific aims of this project are:

  • extensive surface topography and wettability measurements
  • roughness and wettability analysis
  • correlation of the values in a statistical or empirical model


To develop a relationship between the wettability and roughness of the nanostructured surface for better design of biomedical devices

Skills and experience

You will need:

  • a strong background in surface chemistry and mathematics
  • some knowledge about atomic force microscopy and mathematical modelling software.
