SGER: Bacterial Detection Using Acoustic Wave Sensors

本研究是一项短期可行性研究，旨在评估声波传感器在食品病原体检测中的应用，以及潜在的许多其他应用。石英晶体微天平将被涂上针对已知食物病原体（例如鼠伤寒沙门氏菌）的特异性抗体，并且由于粘附的病原体细胞的重量而导致晶体频率的变化将表明存在问题微生物。最终，一个包含几个病原体和/或化学传感器的小型微芯片可能足够便宜，可以包括在食品包装中，并用于监控从加工厂到销售点的产品质量。* * *

9814412 Chin This research is a short-term feasibility study to evaluate the use of an acoustic wave sensor for the determination of pathogens in food, and potentially, many other applications. A quartz crystal microbalance will be coated with antibodies specific for a known food pathogen, e.g., Salmonella typhimurium, and the changing frequency of the crystal due to the weight of the adhered pathogen cells will signal the presence of problem microbes. Ultimately, a small microchip containing several pathogen and/or chemical sensors might be inexpensive enough to include in the food packaging and used to monitor the product quality from the processing plant to the point of sale. ***
