Abstract:
A noninvasive transdermal system for detecting an analyte in extracted from or underneath the skin of a subject, said noninvasive transdermal system comprising:a dry chemistry component for interacting with the analyte, said dry chemistry component having a sensitivity which enables it to detect the analyte extracted from or underneath the skin within about 6 minutes or less following application of said noninvasive transdermal system to the skin of the subject, and a wet chemistry component for wetting said dry chemistry component and for transferring the analyte from or underneath the skin to said dry chemistry component in an amount sufficient, so that said dry chemistry component can detect the analyte within about about 6 minutes or less following application of said noninvasive transdermal system to the skin of the subject, wherein said dry chemistry component and said wet chemistry component are stored separate from one another prior to application of said noninvasive transdermal system to the skin of the subject, and wherein said dry chemistry component is in communication with said wet chemistry component following application of said noninvasive transdermal system to the skin of the subject, so that said wet chemistry component can continuously wet said dry chemistry component while said noninvasive transdermal system is applied to the skin of the subject to enable the analyte to interact with the wetted dry chemistry component.
