摘要: Abstract A comparison of electrochemical sensors performance is achieved using self-organized gold nanoparticles (Au NPs) modified HOPG electrode and (Au) thin film as materials. Both electrodes surfaces were functionalized with bisphosphonate receptors (BP thiol). In addition, the between without BP was achieved. To compare performance, silver copper metal ions used analysts. The obtained results show a detection limit 0.5 μM for Au NPs sensor, whereas sensor it about 10 pM. These discussed in terms specific surface footprint.
