Long-living nanobubbles of dissolved gas in aqueous solutions of salts and erythrocyte suspensions

J Biophotonics. 2011 Mar;4(3):150-64. doi: 10.1002/jbio.201000093. Epub 2010 Nov 10.


Results of experiments combining laser modulation interference microscopy and Mueller matrix scatterometry show that macroscopic scatterers of light are present in liquids free of external solid impurities. Experimental data on distilled water and aqueous NaCl solutions of various concentrations as well as physiological saline solution are reported. The experimental data can be interpreted by using a model of micron-scale clusters composed of polydisperse air nanobubbles having effective radii of 70-100 nm. Their concentration increases with the growth of ionic content. We hypothesize that under certain conditions those clusters of nanobubbles can affect the erythrocyte structure.
