  With the advance in material science,silver nanoparticles(AgNPs)are modified by different surface coating.However,how these surface modifications influence the effects of AgNPs to human health are still unknown.We have evaluated the uptake,toxicity,and pharmacokinetics of AgNPs coated with citrate,polyethylene glycol,polyvinylvpyrolidone or branched polyethyleneimine(Citrate AgNPs,PEG AgNPs,PVP AgNPs or BPEI AgNPs).
