Abstract
In this work, a thin film PET based gold electrode (PGE) glucose sensor was fabricated through ultraviolet mediated chemical plating technique. Compared with the most existing wearable thin film gold electrode sensors, the PGE-glucose sensor is simple, low cost and minimum instrumentation was required. The proposed glucose sensor revealed a sensitivity of 22.05 μA mM-1 cm-2 in a linear range from 0.02 to 1.11 mM with a low detection limit of 2.7 μM (S/N = 3). The PGE-glucose sensor had a good selectivity and was not interfered by lactic acid, urea, acetaminophen, uric acid, dopamine and ascorbic acid. Additionally, it exhibited good reproducibility and long-term stability over four weeks. Finally, the disposable PGE-glucose sensor was successfully applied to determine the glucose in sweat and commercial beverage accurately.Entities:
