synthesis of inorganic nanomaterials // polymer nanocomposites // air quality measurements
Nanoparticles are particles that have a diameter smaller than a few 100 nm (0.0000001 m). They have an extremely high ratio between surface area and volume. Because of their small size nanoparticles are floating in the air together with larger particles and aggregates (aerosols). People can absorb nanoparticles in three ways: through breathing; ii) with food; iii) or through the skin. Particles accumulate in the lungs, and some penetrate into the bloodstream, which can affect internal organs. In our laboratory we measure the numerical distribution, that tells us how many nanoparticles with a certain size are present in a unit of volume. For such measurements we require specialized nanoparticle detectors.
