Title: Microbe auto culturing system using nano-sensor
Applicant: Univ Fudan
Patent number: CN101307291
Publication date: November 19, 2008
The invention belongs to the nanotechnology and biomedicine technical field, and particularly relates to a microorganism automatic cultivation system adopting a nano-sensor. The system mainly comprises a specially designed culture flask, a nano-sensor detector and a device for control, display and record. A separation film in the culture flask separates culture solution from pure water or air, and only CO2 can pass through the separation film. After a specimen is inoculated, the culture flask can carry out automatic temperature regulation and shake culture, and, at the same time, can monitor the generation status of CO2 in the flask through detecting the potential difference between electrodes formed by a nano film or a nano wire (rod) array, a metal oxide nano wire (rod) array and a counter electrode arranged on the side of the pure water or air. An obtained signal is transmitted into a computer for analysis and is judged as a positive result once the signal exceeds a preset threshold value, and the computer can automatically give an alarm. The system which can replace the prior automatic cultivation system in current use can improve a positive detectable rate with high sensitivity and simple operation.
