Novel Zinc Oxide Nanostructures Fabrication by Oxygen Plasma Surface Modification and Improvement of Ractopamine Detection

摘要: A feasible method for different ZnO nanostructures fabrication via the O2 plasma surface modification was reported in present work. After as-prepared nanoparticles were dispersed aqueous solution of Na2CO3, resultant nanomatter treated by times at high input power 200 W. It shows observed, such as nanowire, nanosheet, nanoneedles, and nanoparticles. Also, chemical crystal performances depended on duration plasma. On these bases, formation mechanism new nanostructured ZnO-related materials discussed. In comparison with pristine ZnO, modified (p-ZnO) exhibited a relative electrochemical performance sensitivity toward detection ractopamine (RAC) limit 1.18 ng mL−1 within range 5–500 mL−1. hints that p-ZnO nanostructure could be used alternative biosensor food additives.
