“…Most importantly such an approach allows the translation of laboratory based electrochemical systems into the field. These interesting features have enabled the use of SPEs in the development of analytical methods for determination of many analytes in different samples, such as pharmaceutical formulations, [1,2] clinical samples, [4] microbiology field samples, [5] liquid (bio)fuels samples, [6] environmental samples, [7,8] and heavy metal ions in different samples. [9] Due to the possibility of mass production (low cost per unit), SPEs can be often used as disposable devices and, in this case, common problems of classical solid electrodes, such as surface passivation/contamination and tedious cleaning processes can be avoided.…”

This review addresses the use of screen-printed electrodes (SPEs) coupled to flow systems such as flow injection analysis (FIA), batch injection analysis (BIA), and high-performance liquid chromatography (HPLC) systems over the last six years (since 2014). The combination of SPEs and flow systems is a powerful synergy to increase the throughput of measurements, improve electrode lifetime, and reduce reagent consumption and waste generation. Recently, commercial flow cells for SPEs were made available by different companies and potential new users that are unable to construct homemade electrochemical flow cells have been attracted to work in the area. This overview aims to show both trends and future potential for the development of new methods useful for modern electroanalysis and/or portable applications.

“…SPEs are disposable electrochemical devices that avoid tedious pre-treatment steps. Hence, they are suitable for on-site and real-time sensing [ 23 ]. Moreover, the use of screen-printing technology also offers other interesting advantages, such as electrodes with different spatial distributions, appropriated for miniaturized devices [ 24 ] and the use of small sample volumes.…”

Electrogenerated chemiluminescence (also called electrochemiluminescence (ECL)) has become a great focus of attention in different fields of analysis, mainly as a consequence of the potential remarkably high sensitivity and wide dynamic range. In the particular case of sensing applications, ECL biosensor unites the benefits of the high selectivity of biological recognition elements and the high sensitivity of ECL analysis methods. Hence, it is a powerful analytical device for sensitive detection of different analytes of interest in medical prognosis and diagnosis, food control and environment. These wide range of applications are increased by the introduction of screen-printed electrodes (SPEs). Disposable SPE-based biosensors cover the need to perform in-situ measurements with portable devices quickly and accurately. In this review, we sum up the latest biosensing applications and current progress on ECL bioanalysis combined with disposable SPEs in the field of bio affinity ECL sensors including immunosensors, DNA analysis and catalytic ECL sensors. Furthermore, the integration of nanomaterials with particular physical and chemical properties in the ECL biosensing systems has improved tremendously their sensitivity and overall performance, being one of the most appropriates research fields for the development of highly sensitive ECL biosensor devices.

In this work, unmodified screen-printed electrode (bare SPE) and Sb-film modified SPE (SbFSPE) sensors were employed for the analysis of trace amounts of Pb(II) in non-deaerated water solutions. The modified electrode was performed in situ in 0.5 mg/L Sb(III) and 0.01 M HCl. The methodology was validated for an accumulation potential of –1.1 V vs. Ag/AgCl and an accumulation time of 60 s. A comparative analysis of bare SPE and SbFSPE showed that the detection and quantification limits decrease for the bare SPE. The method with the bare SPE showed a linear response in the 69.8–368.4 µg/L concentration range, whereas linearity for the SbFSPE was in the 24.0–319.1 µg/L concentration range. This work also reports the reason why the multiple standard addition method instead of a linear calibration curve for Pb(II) analysis should be employed. Furthermore, the analytical method employing SbFSPE was found to be more accurate and precise compared to the use of bare SPE when sensors were employed for the first time, however this performance changed significantly when these sensors were reused in the same manner. Furthermore, electrochemical impedance spectroscopy was used for the first time to analyse the electrochemical response of sensors after being used for multiple successive analyses. Surface characterisation before and after multiple successive uses of bare SPE and SbFSPE sensors, with atomic force microscopy and field emission scanning electron microscopy, showed sensor degradation. The interference effect of Cd(II), Zn(II), As(III), Fe(II), Na(I), K(I), Ca(II), Mg(II), NO3– Bi(III), Cu(II), Sn(II), and Hg(II) on the Pb(II) stripping signal was also studied. Finally, the application of SbFSPE was tested on a real water sample (from a local river), which showed high precision (RSD = 8.1%, n = 5) and accurate results.
