We present in detail the most known and commonly used methods for calculation of electrode electroactive area ([Formula: see text]) heterogeneous electron transfer rate constants text]). The correct procedure these parameters is often disregarded due to either lack a minimum theoretical background or oversimplification each method's limitations prerequisites. aim this work provide as well detailed guide implementation measurements by impressing upon electrochemists that need be considered so...
3D printing technology is a tremendously powerful to fabricate electrochemical sensing devices. However, current conductive filaments are not aimed at applications and therefore require intense activation protocols unleash suitable performance. Current methods based on (electro)chemical (using strong alkaline solutions organic solvents and/or treatments) or combined approaches time-consuming hazardous chemicals dedicated operator intervention. Here, pioneering spark-discharge-activated...
This work describes fully integrated multifolding electrochemical paper-based devices (ePADs) for enhanced multiplexed voltammetric determination of heavy metals (Zn(II), Cd(II), and Pb(II)) using tunable passive preconcentration. The paper integrate five circular sample preconcentration layers a 3-electrode cell. hydrophobic barriers the are drawn by pen-plotting with ink, while electrodes deposited screen-printing. exploit wicking ability cellulose to perform target analytes, resulting in...
In this work, we investigated the effect of multi-walled carbon nanotubes (MWCNTs) and bio-graphene (bG) on structure activity glucose oxidase (GOx), as well performance respective electrochemical biosensors. Various spectroscopic techniques were applied to evaluate conformational changes in GOx molecules induced by presence MWCNTs bG. The results showed that flavin adenine dinucleotide (FAD) prosthetic group GOx, tryptophan residues exposed a more hydrophobic environment. Moreover, caused...
This study endeavored to design and develop an innovative closed-loop diagnostic therapeutic system with the following objectives: (a) noninvasive detection of glucose concentration in sweat utilizing nanonengineered screen-printed biosensors; (b) management measured data through a specialized computer comprising both hardware software components, thereby enabling precise control responses via patch-based nanomedicine delivery system. initiative addresses significant challenges inherent...
This work reports the fabrication of integrated electrochemical fluidic paper-based analytical devices (ePADs) using a marker pen drawing and screen-printing. Electrodes were deposited on paper screen-printing with conductive carbon ink. Then, desired patterns formed substrate by commercial hydrophobic an inexpensive computer-controlled x-y plotter. The working electrode was characterized cyclic voltammetry scanning electron microscopy. utility PADs is demonstrated through determination...
