The authors conclude that more work is required to see if the conclusions drawn for ultrafine air pollution particles can be extrapolated to engineered nanoparticles, especially because of widely varying characteristics of different kinds of nanoparticles.</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue><custom1><style face="normal" font="default" size="100%">IEEE Transactions on Nanobioscience</style></custom1><section><style face="normal" font="default" size="100%">331</style></section></record></records></xml>
