The importance of evaluating the real metal concentration in nanoparticles post-synthesis for their applications: A case-study using silver nanoparticles
(Elsevier Science Bv, 2016)To determine whether the effect observed in a study is related to the nanoparticle only or to their synergic effect with the "free" metal ions, the real concentration of silver (104 +/- 8 and 100 +/- 2 mg L-1) after AgNP ...
