HOw technology is changing our health. This week: Selfcleaning stickers

A U.S. company has created self-cleaning crystals that are being trialled in a U.S. airport to make security checkpoints more hygienic.

The so-called NanoSeptic device has tiny crystals and, through a process called photocatalysis, when light hits the crystals they react with oxygen to break down contaminants on our luggage.

This reaction is continuous so creates a self-cleaning product that’s said to be stronger than bleach. The product is available as a large sticker and can be attached to handles and inside security trays.

The continuously selfcleaning linings should prevent contamination between items placed in the tray.
