Research: Projects and highlights
Mobile electronics for medical diagnosis and chemical analysis
To develop portable quantitative tools for point-of-care medical diagnosis and on-site chemical analysis, from standard disc players to smartphones, from traditional microfluidic devices to paper strips. We are also interested in the de novo fabrication of electrochemical biosensors based on functional DNA nanoswitches (e.g., aptamers and DNAzymes).
Analytical electrochemistry at molecular interfaces
Exploring self-assembled monolayers (SAMs) as model systems for understanding interfacial charge/mass-transfer and molecular recognition processes; from solid-state electrical characterization of metal-molecule-semiconductor junctions to electrochemical examination of supramolecular host-guest (e.g., CB[7] and ferrocene) interactions.
Applied nanomaterials for biochip application and beyond
To tailor the surface property of different materials for practical applications, from the preparation of simple and safe waterproof coatings to the benchtop replication of designed nanostructures. We are also interested in the fundamental understanding of superhydrophobicity in terms of its molecular/nanostructural origins.
