General representation of the structure and chemical composition of the engineered nanomaterials (ENMs). evaluated in this work. (a) Depiction of the whole composition of an ENM with the corresponding counterparts without doping and surface coating shown below; (b) Representation of the different ENMs core compositions; (c) and (d) Ball-and-stick model representation of the different doping and coating types evaluated for the ENMs, respectively
