Development of LabPatch-alcohol as a Noninvasive Skin Patch to Detect Blood Alcohol Concentrations
January 3, 2024 updated by: Scott Lukas, Mclean Hospital
Development of LabPatch-alcohol: A Wearable Biosensor for Detecting Alcohol in Interstitial Fluid
This study is designed to test LabPatch-alcohol, a wearable, non-invasive biosensor Band-Aid like patch that is designed to detect real-time changes in interstitial alcohol concentrations in human subjects.
The changes in interstitial alcohol concentrations will be compared to blood alcohol concentrations to determine the patch's validity against the gold standard.

Detailed Description
Nanotechnology has the potential to become a powerful tool in addiction medicine.
The potential utility for passive, non-invasive wearable alcohol monitors is great and could play a major role in public safety as well as in both research, clinical, and treatment settings.
Clinitech, LLC has developed LabPatch, an electronic bandage that continuously and imperceptibly samples interstitial fluid from the skin surface and measures relevant biomarkers in the fluid.
The patch uses novel nanowire technology to sample the interstitial fluid from just underneath the skin and then uses an electrochemical reaction to measure either glucose or alcohol concentration.
The participants' interstitial alcohol concentration (IAC) will be measured via LabPatch-alcohol at the same time points as blood samples so that a direct comparison can be made.
Thus, the LabPatch-alcohol will be tested as the participant's BAC rises and falls through the legally intoxicated concentration (0.08%), and the goal is to match measures obtained via the prototype LabPatch-alcohol with whole blood alcohol concentrations.
The LabPatch operational circuit lies on the underside of the bandage.
The circuit surface is placed in contact with the skin by the application of the elastic adhesive bandage with a contact tension that provides modest pressure, as in the case of a conventional wound bandage.
The temperature of the skin is measured electrically and the consistency of temperature is used to verify good contact and to monitor continued contact.
The entire process takes 3-5 seconds to collect the sample, a pause for 1 sec and then 3 additional seconds to conduct the analysis.

Time Frame |
---|---|---|
Interstitial and Blood Alcohol Concentrations
Time Frame: Both samples will be collected at baseline and at 2.5 to 5 minute intervals for up to 2.5 hrs after a 0.9 g/kg dose of alcohol.
|
Interstitial (from the skin surface) alcohol concentrations will be obtained via the LabPatch band-aid while at the same time blood samples will be collected in an attempt to correlate the two.
The LabPatch-alcohol is a completely noninvasive device and the goal is to determine is precision against the gold standard--blood alcohol concentrations.

Both samples will be collected at baseline and at 2.5 to 5 minute intervals for up to 2.5 hrs after a 0.9 g/kg dose of alcohol.
