Dr Siyi Min Wins the Best Conference Poster Award at the IEEE-NEMS 2021

Dr Siyi Min, a PhD graduate in the HKU-SUSTech Joint PhD Programme, has won the Best Conference Poster Award at the 16th IEEE International Conference on Nano/Micro Engineered & Molecular Systems (IEEE-NEMS) held from April 25th to 29th, 2021 in Xiamen, China. Dr. Min has been supervised by Dr. Wen-Di Li of HKU Department of Mechanical Engineering and Prof. Xing Cheng of SUSTech Department of Materials Science and Engineering. IEEE-NEMS is a premier international conference series sponsored by the IEEE Nanotechnology Council and focuses on the promotion of advanced research areas related to M/NEMS, nanotechnology, and molecular technology.

Dr. Min’s presentation in this conference is entitled “Spectrometer-free Refractometric Sensing Using Image Recognition on Centimeter-scale Gradient Nanostructures”, which is based on her PhD thesis. The research reported an ultrasensitive sensor that can detect an angstrom-thick layer of adsorbed molecules through image acquisition and processing. When the sensor is illuminated with narrowband light (such as from an LED), the intensity pattern recorded on the metasurface changes with the surface-adsorbed molecules, enabling label-free, sensitive, and spectrometer-free molecular detection. This novel sensing scheme has potential to be applied in the daily applications of molecular detection for food safety, environmental quality monitoring, point-of-care biomedical detection.
