This paper describes a simple, low-cost, and highly flexible rapid prototyping method to construct electrochemical paper-based analytical device (ePAD) for multiplexed analyte determinations. The ePAD was composed of two cell (EC) compartments, separated by hydrophobic barriers wax, screen-printed electrodes (SPEs) deposited directly over the surface filter paper. entirely constructed using an inexpensive craft cutter printer with no needed wax printer. involves steps: deposition SPEs...
Alzheimer’s disease (AD) is a neurodegenerative condition that affects large number of elderly people worldwide and has high social economic impact. The diagnosis AD in early stage can significantly improve the evolution prognosis disease. We report use A Disintegrin And Metalloprotease 10 (ADAM10) as blood biomarker for AD. simple, low-cost, sensitive, disposable microfluidic platform (DμP) was developed ADAM10 detection plasma cerebrospinal fluid based on electrochemical immunosensors....
Abstract In this work, a simple procedure for construction of disposable electrochemical paper‐based analytical devices (ePADs) by screen‐printing using low‐cost materials and home craft electronic printer is proposed. The were constructed liner paper as substrate carbon ink prepared with graphite powder wood glue. ePAD was evaluated an sensor biosensor. proposed conductive carbon‐based can be easily eco‐friendly non‐toxic material. developed to produce used sensor, at less than US $0.20 per device.
Sepiolite clay mineral was used as a support for the immobilisation of peroxidase enzyme from ingá-cipó (Inga edulis Mart.) and with graphite powder, multi-walled carbon nanotubes (CNTs), oil, nafion 0.5% (v/v) in development new biosensor determination antioxidant tert-butylhydroquinone (TBHQ) by square-wave voltammetry (SWV). For optimisation application biosensor, several parameters were investigated to determine optimum experimental conditions using SWV. The best performance obtained 0.1...
This work presents the results of production and characterization etched saturated fiber Bragg gratings (ESFBGs) functionalized with gold nanoparticles (AuNPs) as a refractive index sensor. Saturated (FBGs) are produced by directly exposing phase mask to laser beam generate interference pattern in hydrogenated fiber. An iris variable diameter is used select central portion beam; 2 4 mm diameters inscribe gratings. ESFBG exhibits sensitivity over broader range indices reflection spectrum...
