Excimer laser-induced electrochemical activity in carbon ink films

Mercury Free Determination of Lead by Differential Pulse Anodic Stripping Voltammetry onto Silver-Plated Rotograved Carbon Electrodes

“…Consequently, printed tapes obtained that way were distinguished by a larger thickness (10 mm) and ten times lower resistance values (50 O cm 71 ) than those obtained previously [18]. By this way, the features of CARPEs were very close to those of screen-printed electrodes [19]. Figure 1 shows DPASV curves at CARPEs for 10 ppb lead from three different nitric acid media.…”

Development of disposable low density screen-printed electrode arrays for simultaneous electrochemical measurements of the hybridisation reaction

“…To explain such behaviour, some authors consider that the binder can be thought to cover some of the active sites on the electrode surface and the voltammetric behaviour observed can be plausibly explained in terms of ''partial coverage'' model [15,16,18]. This model, developed by Amatore et al [17], states that local non-linear diffusion effects may arise as a result of partial coverage of an electrode surface by adsorbed substances blocking the transfer of electrons between the electrode and solution species.…”

Argon plasma treatment to enhance the electrochemical reactivity of screen-printed carbon surfaces

“…In all these studies, it was found out that the presence of the polymer binder at the electrode surface deeply affects the electrochemical reactivity of the SPCEs [10,11]. The polymer binder could act as a blocking layer that could decrease the rate of the electronic transfer at the electrode-solution interface [12]. Thus, a pre-treatment step of the SPCE surface is often required in order to minimise the effect of the polymer binder on its electrochemical reactivity.…”

“…Others physical procedures were also reported in the literature. For instance, excimer laser was used by Osborne et al in order to enhance the electrochemical reactivity of the SPCE [12]. The authors themselves speculated that the UV radiation from a 193 nm excimer laser source could remove the polymer binder from the exposed surface.…”
