A solution that detects minute presence of ozone, even in cells

ozone in the stratosphere protects the earth from harmful ultraviolet rays. But when in the troposphere, near the ground level, it acts as a pollutant. Though it is not emitted directly, emissions from car engines or industrial operations react to form ozone. Inhaling it can irritate the respiratory system, worsen bronchitis and asthma, and harm heart and lung functions.

Scientists from the University of Pittsburgh, the US, have developed a method that can help detect ozone even in minute level
