Laser-Induced Graphene Electrode Fabrication

LIG working electrodes were designed in CorelDraw consisting of a circular working area (3.0 mm) connected to a stem (14.3 × 2 mm) that leads to a bonding pad area (2.9 × 2.5 mm) based on previous work^{19 (link),46 (link)}. In summary, LIG electrodes were engraved on Kapton film using a CO₂ laser (VLS2.30DT, Universal Laser Systems, Inc., Scottsdale, AZ, US) at 75% speed, 40% power, and 1000 PPI. A passivation layer of nitrocellulose lacquer was applied to the stem area, and a metallic tape was incorporated into the bonding pad area of the working electrode. Platinum nanoparticles (nPt) were coated on the working electrode via electrodeposition by immersing the working electrode in a solution of 1.44% (v/v) chloroplatinic acid and 0.002% (v/v) lead acetate and applying a constant potential of 10 V for 90 s, as described by Moreira et al. (2022).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
