The internalization of AgNPs into A549 cell after exposure with different concentration of AgNPs suspension at 37 °C for 1 h. (a) Mass delivered to A549 cell (Md, pg) against to the increase of given mass (MT, μg) of nAgcontrol, CA-nAg, FA-nAg and TA-nAg suspension. The dashed line was the trend line and the dotted line was the Langmuir rule line; (b) the mass of AgNPs internalized to A549 cell (Mi, pg) against to Md. The solid color lines were fitted based on logistics model.
