SGER: Bacterial Detection Using Acoustic Wave Sensors

9814412 Chin本研究是一项短期可行性研究，旨在评估使用声波传感器测定食品中的病原体以及许多其他潜在应用。 石英晶体微量天平将涂有已知食物病原体的特异性抗体，例如，由于粘附的病原体细胞的重量，晶体的频率变化将表明问题微生物的存在。 最后，含有几种病原体和/或化学传感器的小微芯片可能足够便宜，可以包含在食品包装中，并用于监测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. ***
