Investigations are presented for the development and testing of a sensor for the early stage detection and monitoring of biofilm formation. The sensor is based on the well known quartz crystal microbalance technology (QCM). The QCM detectors are integrated into the water flow system and provide continuous in-situ signals. The main objectives of the research are the evaluation of optimal operation conditions and the modification of the quartz resonator surface promoting a preferred cell attachment onto the quartz sensor surface. The miniaturization degree of the mass sensitive detector modules permits the integration into industrial plants, e.g., in order to control and ensure perfect hygienic conditions. First results of the lab study using Pseudomonas putida cultures are presented and discussed.
本文介绍了一种用于生物膜形成早期检测和监测的传感器的开发与测试研究。该传感器基于著名的石英晶体微天平技术（QCM）。QCM探测器集成到水流系统中，可提供连续的原位信号。本研究的主要目标是评估最佳操作条件，并对石英谐振器表面进行改性，以促进细胞优先附着在石英传感器表面。质量敏感探测器模块的小型化程度允许其集成到工业设备中，例如用于控制和确保完美的卫生条件。文中展示并讨论了使用恶臭假单胞菌培养物进行实验室研究的初步结果。
