报告摘要:

Biochemical sensors are now widely used in the fields ranging from clinical, environmental through to agricultural and food industry. They are serving as critical components in fundamental biological study, general health condition monitoring, disease screening and diagnosis, and environmental pollution control.

With the rapid developments in nanotechnology, computer science and artificial intelligence, people are now expecting to make things smarter and smaller but with higher performance. Therefore, the next-generation biosensors are expected to be highly sensitive, stable and integrable. The conventional surface plasmon resonance (SPR) based systems have been a standard in biochemical sensing. Unfortunately, sensitivities offered by this technology can no longer satisfy our needs in research on the level of individual molecules. In addition, most of the electrochemically based biosensors rely on the reaction between the target analytes and their specific enzymes. The degradation of the enzyme activity and corrosion of the metal electrodes make them only functional for short-term. Also, the performance of the sensors is highly influenced by the environmental conditions like temperature and humidity. I will introduce my study that is mainly focused on developing highly sensitive sensors that are appropriate for long-term use. At the same time, we also take efforts to make the sensor amenable to scalable fabrication and integration with circuitry. We also develop the sensors that can not only quantify concentrations, but also probe their molecular structures.
