Abstract:
Atmospheric aerosol particles of sizes less than 2.5 microns affect public health in cities. Understanding the fine structures of aerosol particles is important to decipher their source. Here, we use a novel spectroscopic and mechanical microscopy technique of 10 nm spatial resolution to reveal the nanoscale structures of individual aerosol particles.
