We further systematically characterized the electrochemical parameters of fabricated LIG-Es to evaluate the device-to-device variation and storage stability, which are important considerations for commercial applications and field deployability. Taking the electroactive area as the key index, our preliminary analysis indicated a device-to-device variation of less than 8% RSD (Fig. ) and activity loss of below 30% over four weeks of storage at ambient temperature (Fig. ). With the above results in mind, we concluded that the porous conductive structure of LIG-E presented here successfully translates into stable and large electroactive surfaces for electrochemical detection, with fast electron transfer rates.
