Polystyrene nanospheres applied in optical sensors

29 April 2016

Researchers at Xiamen University in China developed a new methodology to obtain honeycomb-like oxygen-sensitive polystyrene nanospheres.
They found that the nanospheres exhibited satisfactory ratiometric luminescence responses to O2. More importantly, they displayed distinct change from red to blue when exposed to air from a nitrogen atmosphere. These prepared polystyrene nanospheres can potentially be used as anti-counterfeit labels in the recognition of forged items, or as a dynamic signage for on shelf food packaging, since many foods are kept in a vacuum or in an inert gas, such as carbon dioxide or nitrogen. An article about the research is published in Sensors and Actuators B: Chemical.
