While it will not quite make the washing machine redundant, treated clothing needs to be washed far less often and is easier to clean when finally laundered...
The technology uses microwaves to fix microscopic nanoparticles permanently to the fibres of clothing. These nanoparticles can then have a range of chemical properties attached to them to produce a surface impenetrable to water and able to kill bacteria.
