Windows with nanostructured coatings can cure ‘sick’ buildings

Harmful organic molecules in the indoor air can cause adverse health effects—a problem known as the ‘sick building syndrome’. Current air-cleaning technologies require both energy and upkeep, but a promising new solution is being developed at Uppsala University—window glass with nanostructured coating based on titanium dioxide which uses sunlight to remove organic pollutants from indoor air by passing it between the inner panes of the window.
