Amid the global challenge of controlling the spread of the novel coronavirus, there is a strong demand for testing methods that provide higher accuracy than antigen antibody tests and shorter turnaround times than PCR tests. Assistant Professor Zhang is engaged in the research and development of biosensors that can rapidly and sensitively detect trace amounts of biomaterials in specimens. Utilizing nano-fabrication techniques, she creates silicon "nano wires" and collaborates with computational science to optimize the sensor's structure, electrical properties, and surface conditions. The goal is to detect specific substances efficiently and sensitively. In the future, the aim is to develop a measurement system capable of simultaneously detecting multiple biomaterials with a single sample solution collected in medical settings.
