Novel and flexible disposable laser-engraved Kapton (LEK) electrodes modified with graphene conductive inks have been developed for dopamine and Interleukin-6 (IL-6) detection. The LEK sensors exhibit high reproducibility (RSD=0.76%, N=5) and stability (RSD=4.39%, N=15)after multiple bendings, and thus make the sensors ideal for wearable and stretchable bioelectronics applications. We have developed graphene conductive ink- PEDOT:PSS (G-PEDOT:PSS) and polyaniline (G-PANI) based electrode coatings for working electrode modification to improve the sensitivity (41.41 times higher for screen printed electrode with G-PEDPT:PSS ink modification),and limit of detection (LOD) . We have further compared the performance of the fabricated electrodes with commercially available screen-printed electrodes (SPE), screen-printed electrodes modified with G-PEDOT:PSS (SPE/G-PEDOT:PSS) and G-PANI (SPE/G-PANI). SPE/G-PANI has a lower LOD of 0.632 μM, compared to SPE/G-PEDOT:PSS (0.867 μM) and SPE/G-PANI(1.974 μM). The lowest LOD of the LEK/G-PANI sensor (0.4084 μM, S/N=3) suggests that it can be a great alternative to measure dopamine levels in a physiological medium. Additionally, LEK/G-PANI electrode has excellent LOD (2.6234 pg/mL) to detect IL-6.GRAPHENE-CONDUCTIVE INK COATED LASER ENGRAVED KAPTONELECTROCHEMICAL BIOSENSOR FOR THE DETECTION OF DOPAMINE AND IMMUNESENSING.
