Functionalized Ni@SiO2 core/shell magnetic nanoparticles as a chemosensor and adsorbent for Cu2+ ion in drinking water and human blood.
Fluorogenic based nitrobenzofuran-functionalized Ni@SiO(2) core/shell magnetic nanoparticles have been prepared by sol-gel grafting reaction. Their ability to detect and remove metal ions was evaluated by fluorophotometry. The nanoparticles exhibited a high affinity and selectivity for Cu(2+) over competing metal ions. Furthermore, the nanoparticles efficiently removed Cu(2+) in drinking water and human blood.
