Skin cancer is amongst the most common forms of cancers in the world with its highest incidence in Australia, New Zealand, the US and Europe.
The World Health Organisation (WHO) estimates that between two to three million non-melanoma and 132,000 melanoma skin cancers are diagnosed each year.
So researchers from the School of Chemistry and Chemical Engineering at Queen’s University Belfast, UK, have developed an early warning sunburn indicator that could tell sunbathers when to take to the shade.
The team, led by Dr David Hazafy, have developed a strip of plastic – containing ‘smart’ ink – which turns colourless from an initial blue colour to indicate a high exposure of ultraviolet light from the sun. This should prompt the user to move into the shade before burning, reducing the risk of skin cancer.
