Any surface exposed to the environment will, initially be coated with the surrounding environmental constituents (e.g. water, electrolytes and various organic and non-organic substances). It is likely that the presence of water, electrolytes and other substances could provide the stimulus for microbial growth and its further colonisation onto the material surfaces in vitro. Subsequently, any surface or material will likely to be affected in whatever its role or function. If the surface or material is used in a hospital or a food preparation environment, then it is essential that surface be free from any bio-contamination.
