TEM characterizations of AgNPs and stability of AgNPs suspension in CM (20 μg ml−1 at 37 °C). (a) Size distribution of pristine nAg (p-nAg), nAgcontrol, CA-nAg, FA-nAg and TA-nAg characterized by TEM at least 200 particles. (b) UV–Vis absorption spectrum of nAgcontrol, CA-nAg, FA-nAg and TA-nAg suspension. (c) UV–Vis spectra over 60 min. (d) The ratios of the absorbance to the initial absorbance at λmax over 60 min fitted with first order removal model. (e) Hydrodynamic diameters of AgNPs suspension over 30 min by DLS.
