英文摘要	A self-powered biosensing system based on triboelectric nanogenerator (TENG) for bacterial DNA detection is invented and a vertical contact-separation TENG was designed to provide a steady power supply to a detection bioreactor. A carboxyl-functionalized capture probe was modified on etched indium tin oxide (ITO) glass, with which target bacterial DNA could be recognized. Meanwhile, multi-walled carbon-nanotubes (CNT)-modified signal probe was designed to amplify the detection signal due to its excellent electrical conductivity. The selfpowered biosensing system could measure the variation in output voltage and be highly sensible with a low detection limit at 0.084 pM of target DNA. In addition, a mathematical model based on the Freundlich isotherm was built to simulate the DNA detection process, and it was feasible to simulate the calibration equation and detection range. A portable self-powered biosensing device was made by integrating miniaturized TENG and bioreactor in a 3D-printed mold, with which the presence of bacterial DNA could be instantly indicated by LED (light-emitting diode). This study provided a useful platform for quick bacterial DNA detection and paved the way for further development of pocket diagnosis with TENG-based biosensing systems.
