Nowadays, there is increased demand for wearable sensors sweat glucose monitoring in order to facilitate diabetes management a patient-friendly and noninvasive manner. This work describes device the form of an electrochemical ring (e-ring) fabricated by 3D printing. The 3D-printed e-ring consists three carbon-based plastic electrodes (fabricated using conductive filament) integrated at inner side ring-shaped flexible holder nonconductive filament). modified with electrodeposited gold film...
In this article, the field of mercury film electrodes (MFE's) as electroanalytical devices is reviewed. Special emphasis placed on area new materials substrates for coating and plating process well developments related to electrode modification used achieve an increase in either selectivity and/or sensitivity analysis. Other topics discussed are microelectrodes, disposable some novel, innovative or less explored applications methods using MFE's. The future prospects, potential uses...
This work reports on the fabrication, characterization and applications of Nafion-coated bismuth-film electrodes (NCBFE's) for determination trace metals by anodic stripping voltammetry (ASV). A NCBFE was typically prepared first applying a 5 microl drop 1% Nafion solution onto surface glassy-carbon rotating-disk electrode. After evaporation solvent, Bi film plated electrode in situ(i.e. spiking sample with 1000 microg l(-1) Bi(iii) simultaneous electrolytic deposition metal ions bismuth at...
This article is intended as an overview of bismuth-based electrodes applied to electrochemical stripping analysis. These rely on a bismuth or bismuth-modified active surface and, while they have analytical performance comparable mercury electrodes, are characterized by negligible toxicity in comparison their counterparts. properties make them ideally suited sensors for trace monitoring Topics covered this review the main types and fabrication, characteristics common interferences analysis...
This work reports the fabrication of a functional and fully integrated electrochemical device manufactured via single-step 3D printing approach its proof-of-concept applicability to sensing. The is fabricated entirely by using printer equipped with two heads. It features three conductive polymer electrodes (working, counter, pseudo-reference) printed from carbon-loaded polylactic acid (PLA) filament an electrode holder PLA non-conductive filament. 3D-printing enables devices significant...
The two-dimensional <bold>Ca-MOF</bold> shows a dual function as sorbent and an electrochemical sensor for heavy metal ions, which is reported the first time MOF material.
Abstract Fused deposition modeling (FDM) represents a state‐of‐the‐art 3D printing technology that holds great promise in the field of electrochemistry as fast, in‐house, and digital fabrication method sustainable sensors. Despite progress FDM, existing practical printed sensors still require post‐printing treatment to improve their operational features, either through (electro)chemical surface activation or modification with external functional materials. Herein, novel lab‐made conductive...
In this article, the results of some recent investigations on two types bismuth-modified carbon paste electrodes are presented. first study, bismuth-film electrode (BiF-CPE) operated in situ and employed anodic stripping voltammetry Cd(II) Pb(II) at low μg L−1 level was interest view choosing proper Bi(III)-to-Me(II) concentration ratios (where Me: Pb or Cd). Such optimization has resulted significant improvement detection limits down to 1.0 Cd 0.8 for Pb, which allowed us apply BiF-CPE...
