Single‐Step Reagentless Laser Scribing Fabrication of Electrochemical Paper‐Based Analytical Devices

Abstract: A single-step laser scribing process is used to pattern nanostructured electrodes on paper-based devices. The facile and low-cost technique eliminates the need for chemical reagents or controlled conditions. This process involves the use of a CO laser to pyrolyze the surface of the paperboard, producing a conductive porous non-graphitizing carbon material composed of graphene sheets and composites with aluminosilicate nanoparticles. The new electrode material was extensively characterized, and it exhibits high… Show more

“…Since the pioneering report from Dungchai and co‐workers , the use of paper substrates for the development of electrochemical paper‐based analytical devices (ePADs) has become increasingly popular . Different techniques can be explored to fabricate electrochemical sensors on paper platforms including sputtering , screen‐printing , stencil‐printing , laser scribing , inkjet‐printing and direct drawing with pen or pencil . Alternatively, electrodes can also be integrated on paper using microwires or even commercial screen‐printed electrodes .…”

“…143 Since this seminal work, a wide range of techniques have been developed to fabricate and pattern electrodes on μPADs; including screen printing and inkjet printing of conductive inks, 144 evaporation or sputtering of metals, 145 as well as "reagentless" techniques such as laser scribing. 146 Very recently, exciting advances have been made in relation to the detection of nucleic acids on μPADs. For example, Crooks and co-workers presented an origamiinspired device comprising multiple sliding layers of paper that allowed for electrochemical detection of short target DNA sequences.…”

“…In the design of a three‐electrode amperometric cell, electrodes have to be separated from each other. This could be made by: i) using multiple layers, ii) direct printing (e. g., pencil‐drawn, pen‐on‐paper, or laser scribing), iii) stencil‐ or screen‐printing electrodes, or iv) using external wire electrodes ,. Moreover, thin‐ or thick‐film working electrodes (WEs) do not require the use of stencils if reference and counter electrodes (RE, CE) are located on the opposite side of the film …”
