For the experiments, the laser settings were adjusted to meet the requirements of the films according to Table . A standard sensor strip is made of five parallel lines of 5 mm in length distributed across a width of 0.5 mm. An open-top atmospheric chamber was designed to generate a continuous flow of a selected gas (O2 or N2) for the fabrication of LP-NC under controlled gas atmospheres (Figure ). The laser-patterned (LP) samples are labeled according to: LPatmosphere_CNFA1content(/CNFA2content), e.g., LPO2_Ade38090/Glu30010 for a laser-patterned film of a mixture of Ade380:Glu300 (90:10 wt%) as CNFAs under O2 reaction atmosphere.
