Atmospheric aerosols have global effects on human health, environment and climate, and these effects are directly related to the physical and chemical properties of aerosol particles
Raman microspectroscopy technology can realize non-destructive detection of microscopic substances.
In response to this situation, Zhu Tong’s research group from the School of Environmental Science and Engineering of Peking University proposed a universal method for measuring the pH value of single particles.
This research was published online on Analytica Chimica Acta under the title " Water as a probe for pH measurement in individual particles using micro-Raman spectroscopy " .
