Cleaning the kitchen ...

Today I spent some time on domestic chores ... including cleaning the kitchen surfaces, cooker hob etc.  It's not my favourite job!  Fortunately in the future, nanotechnology coatings for such surfaces may make it one less task we have to do regularly.  The coatings will be energised by light and oxidise organic molecules converting them into water and/or carbon dioxide, thus successfully targeting and destroying bacteria cell walls and then the cells' components.  This results in the death and decomposition of the bacteria, eliminating bad odours and reducing the spread of the bacteria itself.  Chemicals which could form part of these phot0-catalytic coatings include titanium dioxide.  This is used in various forms in the food and pharmaceutical sectors.   I can't wait until coatings that utilise the unique properties of such substances are developed and widely available!  Domestic chore bliss!
