title = "A Novel Microfluidics-based SAW Sensor for Ultrafine Particle Detection",
abstract = "Portable sensors are valuable tools for ultrafine particle (UFP) monitoring as they allow for real-time measurements in various environments. At the forefront of portable UFP monitoring, are lab-on-a-chip devices that use surface acoustic waves (SAW) to measure aerosol concentration. However, existing SAW-based UFP detectors rely on the accumulation of particulate matter on the sensor{\textquoteright}s active surface, which makes them unsuitable for in-flow measurements. In this work, we suggest the integration of microfluidics to enable continuous monitoring. With particles actively flowing through the sensitive region, the limitation of standard SAW UFP sensors is overcome. Results indicate that the sensor can provide information not only on the concentration of particles, but also their size.",
