TLDR
The highest toxicity was recorded for AgNPs-CTAB, which resulted with increased Ag uptake in the roots, consequently leading to strong reduction of the root growth and oxidative damage, and it can be concluded that the toxicity ofAgNPs is directly correlated with their size, overall surface charge and/or surface coating.About:
