shows the highest response of ∆R/R0 = -0.3%. Glucose was pre-carbonized at 300 °C according to previous optimization. As recently demonstrated, each CNFA shows a characteristic response to the laser processing parameters, i.e., the incident power and scanning speed. Optimal scan speeds of 189 cm•s -1 and laser power of 1.1 W (SI, pp. S2-3, Figure ) were obtained by optimizing the conductivity and performance of reference LP-NCs (pure adenine-CNFA).
