- the laminar regime unlike the turbulent regime, does not favor surface-microorganism impacts.
- the bacterial adhesion in this case does not depend on the flow conditions, but on the properties of the surfaces themselves and the suspending liquid.
- the adhesion of microorganisms to the glass surface is monitored using a microscope (Leica, x10 objective). Every 10 minutes, an image is taken. By a computer analysis of it, it is possible to determine the percentage of recovery of each image and thus build a curve which represents the percentage of coverage of the surface by the bacteria as a function of the contact time.
- TiO 2 glass becomes more hydrophilic. A circulation of water can thus unhook the bacterial cells in particular dead from the surface of the TiO 2 glass more effectively than from the surface of the bare glass.
- this example demonstrates the self-cleaning property of TiO 2 glass vis-a-vis the bacteria tested. This layer is therefore indicated for applications of at least partial destruction, or stop the development of microorganisms, especially indoors.
