ronment, the determination of trace Hg(II) is important. Atomic absorpt ion and inductively coupled plasma spectroscopic methods are currently widely used. Many publications on this subject focus on electrochemical methods (anodic and potentiometric stripping voltammetry) at a variety of electrode materials. Glassy carbon, goldplated glassy carbon, screen-printed carbon, platinum (Pt) and gold ...

Abstract Conventional electronics have been highlighted as a very unsustainable technology; hazardous wastes are produced both during their manufacturing but also, due to limited recyclability, end of life cycle (e.g. disposal in landfill). In recent years additive processes (i.e. screen printing) attracted significant interest more sustainable approach electronic (printed electronics). Despite...

Creatinine is the final metabolic product of creatine in muscles and a widely accepted biomarker for chronic kidney disease. In this work, we present non-enzymatic sensor based on an electrochemical pretreated screen-printed carbon electrode (PTSPCE) with electrodeposited Cu nanoparticles (CuNPs). To function PoC format, prepared PTSPCE/CuNPs sensors were used as disposable elements portable po...

A novel electrochemical sensor was proposed for the determination of amitriptyline based on the copper oxide (CuO) nanoparticles modified graphite screen-printed electrode. CuO nanoparticles were used to enhance the surface area of the electrode and then improve the sensitivity of the electrochemical sensor. Amitriptyline electrochemical response characteristics of the modified electrode in a p...

A two-dimensional (2D) Sb-modified screen-printed carbon nanofibers electrode (2D Sbexf-SPCNFE) was developed to improve the stripping voltammetric determination of Cd(II) and Pb(II), taking advantage synergistic effect between two nanomaterials. The surface morphology 2D Sbexf-SPCNFE investigated by scanning electron microscopy, energy-dispersive X-ray spectroscopy, Raman spectroscopy. analyti...
