Silver nanoparticles enhance thrombus formation through increased platelet aggregation and procoagulant activity.

abstract：:Dose-response by in vitro testing is only valid if the fraction of the particle dose that deposits onto adherent cells is known. Modeling tools such as the 'distorted grid' (DG) code are common practices to predict that fraction. As another challenge, workflow efficiency depends on parallelized sample preparation, for...
