[nanoPost] Fouling and cleanability of hygienic food contact surfaces

This group has previously investigated the effect of wear on the fouling and cleanability of hygienic food contact surfaces. Surface sensitive analytical techniques including XPS and ToFSIMS, coupled with atomic force microscopy provided data which could be compared with more traditional microbiological and microscopic techniques.
Current research interest primarily lies in the interaction between microorganisms and surfaces. The group has worked on topographical and chemical features which affect this interaction, fabricating surfaces of defined topography where features are of microorganism-dimension. They have also modified surfaces by incorporation of controlled release technology, and nanotitanium anti-microbial mechanisms.
The location of these surfaces affects the mode in which the microorganisms are present: whether as attached microorganisms in the presence of organic soil (e.g. on hygienic surfaces, walls, floors), or as fully hydrated biofilm (e.g. in pipes, or in medical/dental environments), or on surfaces with intermittent exposure to water (e.g. drains, shower curtains etc.)
