WANG RESEARCH GROUP
Microwave Lab-on-Chip
High-Frequency Biological, Chemical and Medical Sensors
We invented highly sensitive and tunable interferometer techniques, which are ideal for building high performance, miniaturized, robust and user friendly sensors.
​
Furthermore, high-frequency signals interact with biological and chemical more effectively when compared with optical frequency signals.
Additionally, broadband measurements provide rich information contents about the tested substance, therefore, enabling label free identification.
So far, we have demonstrated record Qeff of the RF structures, as high as 1E8 when lossy water is measured. We have also shown that the interferometers can be easily tuned from ~ 100 kHz to ~ 50 GHz. Based upon the interferometer techniques, we have developed and demonstrated different microwave LoC systems.
​
Currently, we are working on developing RF gas sensors (RF noses), high-speed single cell RF analyzers (including malaria rapid diagnosis test), single particle and single molecule RF analyzers. Additionally, we are developing high sensitivity and broadband electron spin resonance (ESR) spectrometers and dielectric spectrometers (RF tongues). We also work to miniaturize these sensors.
