Abstract:Excessive exposure to airborne particulate matter (PM), especially PM 2.5 particles, adversely affects human health. Conventional PM 2.5 detection instruments based on light scattering are generally bulky, expensive, and easily affected by particle size and composition. Here, we report a low-cost and compact one-stop PM 2.5 detection platform by integrating a threedimensional (3D) printed virtual impactor with a QCM sensor. To reduce eddy and airflow impact on the side wall and improve the VI lifetime, a compu… Show more
