Effects of silica, polystyrene, and gold nanoparticles on platelet-poor plasma using quartz crystal microbalance with dissipation. Perfusion of fibrinogen-coated polystyrene-coated quartz crystals with platelet-poor plasma in the presence of silica, polystyrene, and gold nanoparticles did not induce significant changes in frequency and dissipation. Representative traces from the third overtone recorded by the device showing the effects of platelet-poor plasma in the presence or absence of (A) silica nanoparticles, (B) polystyrene nanoparticles, and (C) gold nanoparticles on frequency (blue line, left axis) and dissipation (red line, right axis).

Abbreviation: min, minutes; PPP, platelet-poor plasma; sec, seconds.
