| Abstract: | Semiconductor biochemical sensors are regarded as robust tools for the detection of various targets. However, re‐use of these sensors is one of the major obstacles hindering further development. To address this problem, a multi‐objective platform was developed based on magnetic beads and the AlGaN/GaN high electron mobility transistor (MBs AlGaN/GaN HEMT) device. Since the magnetic beads are capable of being fixed and released by inductance coils, the platform enables repeatability and multi‐objectivity during testing. To validate the advantages of the platform, metal ions and prostate specific antigen (PSA) were used. In this study, a platform sensing biochemical responses with a sensor was demonstrated to show the characteristics of reusability, multi‐target sensing, and simplicity, resulting in its promising prospects for widespread applications. |
