Formation of nanoparticles can now be studied molecule-by-molecule
During the last five years, the researchers at the University of Helsinki Physics Department have developed a Particle Size Magnifier (PSM), which is the first particle counter able to detect clusters and particles as small as 1 nm in diameter. The instrument is commercially available through the spin-off company Airmodus. The scientists have also put effort into developing mass spectrometric methods for measuring the composition of the recently born clusters. The results in this study would not have been achieved without this technical development.
Professor Kulmala predicted the existence of neutral molecular clusters already in the year 2000 and their growth mechanisms in 2004.
He says: "Years of systematical research are now bearing fruit. My theoretical predictions have been proven to reflect the reality."
He stresses that knowledge of the formation and growth mechanisms of nanoparticles is needed for understanding the interactions within the climate system. Assessing the global impact requires an extensive data bank and a world-wide observation network.
