Circadian misalignment, caused by shift work or eastward/westward travel, therefore impairs our ability to sleep and remain mentally alert. This is particularly problematic in military and civilian occupations in which human error may result in death; such is the case for transport vehicle operators and medical professionals. As a result, knowing and understanding an individual’s baseline circadian rhythm may be critical in fatigue-related accident prevention strategies. Currently, accurate identification of a person’s circadian rhythm requires salivary melatonin assessment by a plate-based immunoassay, which takes 24 hours and must be performed in a laboratory. Therefore, the goal of this project is to develop and test a user-friendly device that performs nearly instantaneous salivary melatonin assessment. Direct electrochemical quantification of melatonin was performed in water and saliva on a disposable ceramic screenprinted electrode with a chemically modified surface. The peak current of melatonin oxidation in both mediums (water and saliva) was highly correlated (R2 > 0.95) to the concentration of melatonin in the samples. In conclusion we have shown proof-of-concept that melatonin can be directly quantified on a gold electrode. |
