1 However, Cu(2+) release in Cu and Cu-C nanoparticle suspensions caused 40% and 45% of AChE activity reduction, respectively. Copper acetylcholinesterase (Cartwright blood group) Homo sapiens
2 AChE inhibition by bulk Cu and activated carbon particles was also measured for comparison, showing that the inhibition by bulk particles was lower than their counterpart nanoparticles. Copper acetylcholinesterase (Cartwright blood group) Homo sapiens
3 For bulk Cu particles, AChE inhibition was primarily caused by dissolved ions, but mainly by adsorption for activated carbon. Copper acetylcholinesterase (Cartwright blood group) Homo sapiens
4 AChE inhibition by Cu, Cu-C, MWCNT and SWCNT had dose-response relationships, and their median inhibitory concentrations (IC(50)) were 4, 17, 156 and 96mgL(-1), respectively, showing that these nanoparticles may have neurotoxicity and AChE may have potential to be used as a biomarker for nanoparticles. Copper acetylcholinesterase (Cartwright blood group) Homo sapiens
