Smart material patch-type indicators for measuring antioxidant content in foodstuffs

Technology/Research:

Research in this group is on smart materials/membranes and application to diagnostics, environment, medicine and food. They are developing smart material patch-type indicators for specific nanoscale recognition of small and/or large molecules. 

Small molecules include analgesic drugs, metabolites, phenols and acids. Phenols are an important class of antioxidants. Using the smart patches, antioxidant content in foodstuffs can be determined in real-time as well as changes in pH of foodstuffs. The latter could be an indicator of rancidity.

They are also developing smart materials for highly specific detection of large molecules (including proteins and enzymes). They are developing a novel class of hydrogel-based molecular imprinted polymers capable of highly specific protein recognition.

They are also developing portable electrochemical sensor devices based on these materials. The smart materials when integrated with the sensor device are designed to be user-friendly and easy to use.
