Table 2 Physicochemical characterization of tested AgNPs. The main findings in AgNPs characterization are reported for each tested sample. For DLS analyses, the mean size of AgNPs is expressed in terms of hydrodynamic diameter, however this parameter is fully informative only for samples with monomodal distributions. Accordingly, the maximum intensity peaks were also reported to describe more comprehensively samples having multimodal distributions (i.e. 10 nm AgNP-CT and 10 nm AgNP-PVP). The pdI provides a measure of particles uniformity. For UV–Vis analyses, the maximum wavelength (λmax, i.e. the wavelength corresponding to the highest absorbance of AgNPs) and the maximum absorbance value (Hmax) are reported. The λmax and Hmax values were expressed in nanometer (nm) and arbitrary units (a.u.), respectively. Finally, AgNPs size distributions expressed as Feret diameter (mean ± SD, nm) and variation coefficient (%) were obtained from TEM analysis
