“…Traditional endpoints, such as growth curves (Moon et al, 2014;Morelli et al, 2013Morelli et al, , 2012 or other commonly used biomarkers such as the antioxidant molecules (Lee et al, 2013(Lee et al, , 2008Mukherjee et al, 2014) or metal chelating compounds (Gomes et al, 2011), which are reported to be activated as a response to stress induced by nanoparticles, can be useful parameters, but are too unspecific for the kind of stress and quite time-consuming to be measured. In recent papers (Moon et al, 2014;Park et al, 2015), it was demonstrated the ability of SELDI-TOF-MS to discriminate, by protein profiles, even slightly different forms of the same kind of pollutant, thus confirming the superior capability of SELDI in detecting biomarkers that can be used as an early alert for the presence of toxic substances in the environment.…”
