Did you know what happen to that worn out currency note you used to buy groceries?

It got destroyed, eventually. And a new currency note was printed to replace that.

Not any more.

Scientists have developed a new way to clean paper money to prolong its life which could save billions and minimise the environmental impact of banknote disposal.

According to the researchers, Nabil M Lawandy and Andrei Smuk from US-based Solaris Nanosciences Corporation, the main culprit behind getting the currency note grimy is human sebum - the oily, waxy substance the body produces to protect the skin.
