Researchers were seemed to develop a small, touch-based detector that may sight the amount of lithium in a very person's body by using their sweat. The device would provide results in less than 30 seconds and does not need to visit to a clinic. The correct level of lithium within the body would facilitate in controlling symptoms of mental health problems which would include bipolar disorder and depression. Well, having updates on the lithium level within the body would permit the health care providers to maintain a track of whether the patient has been taking the medication as prescribed or not.

HIGHLIGHTS
The level of lithium in the body would help to control mental health symptoms
The blood tests provide an image of the progress of medication
The gel had created controlled surroundings for the electronic portion of the sensor

The recently available strategies of maintaining a track of medication were seemed to be invasive and have their own drawbacks. Whereas on the other hand, blood tests provide an image of the progress of medication, the method was invasive and long. Pill counters, would not assure the measure of actual medication intake. However, with this new device, the researchers would attempt to address this limitation by using the sweat.

The results of the device's performance were actually presented at the fall meeting of the American Chemical Society (ACS) on August 21.

The electrochemical sensing device usually uses a water-based gel which would contain glycerol to sight charged particles of lithium within the sweat that was typically present in minute amounts.

As per Shuyu Lin, PhD, a postgraduate student researcher “although it would not be visible, the human body would constantly produce sweat, usually in very little amounts.”

The gel had created controlled surroundings for the electronic portion of the sensor. In order to trap the lithium ions after they were passed on through the gel, the researchers have used an ion-selective electrode. Well, the accumulating ions would generate a distinction in electrical potential compared with a reference electrode.

This distinction was then utilized to ascertain the concentration of lithium which was present in sweat.

Well, the device has already been tested on individuals, which would include one person on lithium treatment regimen. The researchers have recorded this person's lithium levels before and after taking the medication. Therefore, the results have showed that the measurement fell were close to those who derived from saliva, that previous research had showed to accurately measure the lithium levels.

Though the sensor would still be in the preliminary testing phase, where the researchers aim to incorporate it into a larger yet-to-be-designed system that would offer visual feedback to the provider or the patient.
