Kraft-Based Femtosecond Laser-Induced Graphene for Electrochemical Dopamine Sensing

Langmuir, Год журнала: 2025, Номер unknown

Опубликована: Янв. 25, 2025

In this work, laser-induced graphene from kraft paper (kraft paper-LIG) was employed for the nonenzymatic electrochemical sensing of dopamine (DA). We reported fabrication and characterization a disposable, cost-effective, kraft-based sensor with electrode consisting derived paper. Kraft paper-LIG formed by femtosecond laser modification into three-dimensional (3D) arrangement. Our study labeled that activity can be improved via dual pass (defocused, followed focused lasing). Kinetic analysis showed effective heterogeneous electron transfer rate constant 2.8 × 10-3 cm s-1 using Fe(CN)63-/4- as redox probe. The electrodes successfully detected quantified in phosphate-buffered solution (PBS) within 1-100 μM range. A linear response (R2 = 0.9986) observed, sensitivity 37.381 μA cm-2 μM-1. Furthermore, denoted sufficient selectivity DA electrolytes containing ascorbic acid (AA) uric (UA). also had good stability at ordinary temperature.
