Findings on Biosensing Described by Researchers at National Tsing Hua University

June 18, 2014

By a News Reporter-Staff News Editor at Biotech Week -- Researchers detail new data in Biosensing. According to news reporting from Hsinchu, Taiwan, by NewsRx journalists, research stated, "A 3D rolled-up structure made of a SiO2 layer and a fishbone-like magnetic thin film was proposed here as a biosensor. The magnetoresistance (MR) measurement results of the sensor suggest that the presence of the stray field, which is induced by the magnetic nanoparticles, significantly increased the switching field."

The news correspondents obtained a quote from the research from National Tsing Hua University, "Comparing the performance of the 2D sensor and 3D sensor designed in this study, the response in switching field variation was 12.14% in the 2D sensor and 62.55% in the 3D sensor. The response in MR ratio variation was 4.55% in the 2D sensor and 82.32% in the 3D sensor. In addition, the design of the 3D sensor structure also helped to attract and trap a single magnetic cell due to its stronger stray field compared with the 2D structure."

According to the news reporters, the research concluded: "The 3D magnetic biosensor designed here can provide important information for future biochip research and applications."
