 Research Interests 

Conjugated Polymers for Biological Sensors and Imaging 

 

Water-soluble conjugated polymers are highly efficient at harvesting and emitting light energy. Based on the fluorescence signal modulation of the polymers in response to their electrostatic interaction with oppositely charged analytes, it has driven interest in high-sensitive and rapid-response fluorescence sensors for peptides, proteins, DNAs, and RNAs. Conjugated polymers can also be used as bright fluorescent labels for imaging of biological cells and tissues.

 

 

 

 

Polymer Ferroelectrics for Energy Storage and Memories 

 

Ferroelectric polymers belong to an important family of functional materials which have thermodynamically stable spontaneous polarization states switchable by application of a sufficiently strong external electric field. Vinylidene fluoride-trifluoroethylene copolymers, P(VDF-TrFE)s, are the most thoroughly studied polymeric ferroelectrics and were the first example of a polymer with a well-defined ferroelectric transition behavior. Studies on the ferroelectric polymers are increasingly motivated by their exceptionally excellent electric properties. They are worth exploring as high electric energy density capacitors, electromechanical actuators, piezoelectric or pyroelectric sensors, gate dielectrics in thin-film field-effect transistors (FETs), and rewritable/non-volatile ferroelectric memories.
