DOI: 10.1021/acsomega.3c08402
Abstract: Excessive exposure to airborne particulate matter (PM), especially PM2.5 particles, adversely affects human health. Conventional PM2.5 detection instruments based on light scattering are generally bulky, expensive, and easily affected by particle size and composition. Here,… read more here.
