Influence of polymeric nanoparticles on rheological and electrical properties of RBC suspensions

Popis výsledku v původním jazyce

The influence of polymeric nanoparticles on the rheological and electrical properties of RBC suspensions has been studied. Poly(acrylic acid) particles of different architecture and molecular weight were used, that is, a new core?shell type star polymerwhose interior presents hyperbranched polystyrene bearing arms of poly(acrylic acid) and linear polyacrylic chains with average molecular weights Mn=225 000, 20 000 and 6 000. The star macromolecules possessed in average ten arms with degree of polymerization DP=58. Their shape is spherical with hydrodynamic radius Rh=14 nm determined by the diffusion ordered NMR spectroscopy [1]. On the other hand, the linear poly(acrylic acid) chains adopt rod like form under physiological conditions. Suspensions of polymeric nanoparticles in physiological solution with different mass/number of particle concentration were prepared. The volumetric particle concentrations used in the experiments with red blood cell (RBC) suspensions were 1mg/ml (1.1x101
