Dr Xie's research focuses on the synthesis and fabrication of novel nanostructures (metallic, semiconducting, and dielectric) and their assemblies. Her group then harness such hieratical nanosystems for nanobiotechnology and solar energy. They are currently focusing on ultra-sensitive medical sensors and effective light harvesting for solar cells and expending their applications in enhanced bioimaging and effective charge separation for solar cells. The current projects are listed below:(1) Synthesis and characterization of novel nanostructures by colloidal lithography technique.(2) Metal enhanced fluorescence for ultra-sensitive biosensing. (3) Novel nanostructures for effective light harvesting and charge separation of solar cells.(4) ZnO nanoflowers for protein detection.
