Non-invasive device and method for quantitative determination of oxidants and/or antioxidants in the skin
First Claim
1. A non-invasive device for the quantitative determination of the level of oxidants and/or antioxidants in the skin of a subject comprising:
- a pair of a reference electrode and a working electrode which are connected to electrical voltage measuring means;
a test solution container which is open at a bottom side thereof which is placed on the skin of said subject and is releasably but sealingly affixed to the skin by suitable means, filled with said test solution and permitting contact between said test solution and the skin, and is open at a top side thereof through which said electrodes are immersed in said test solution.

Abstract
A non-invasive device for the quantitative determination of the level of dants and/or antioxidants in the skin of a subject includes a reference electrode and a working electrode which are connected to an electrical voltage measuring device; and a test solution container which is open at a bottom side thereof and which is placed on the skin of the subject and is sealingly but releasably affixed to the skin, is filled with a test solution, and which permits contact between the test solution and the skin. The test solution container further includes a top opening through which the electrodes are immersed in the test solution.

15. A non-invasive method for the quantitative determination of the level of oxidants or antioxidants in the skin of a subject comprising the steps of:
-
sealingly affixing to the skin of the subject a test solution container which is open at the side thereof which is placed on the skin of said subject in a releasable manner by suitable means; filling said container with a suitable test solution, said test solution containing reagents which are capable of being oxidized or reduced by oxidants or antioxidants present in the skin of said subject, respectively; immersing a pair of a reference electrode and a working electrode, which are connected to electrical voltage measuring means, in said test solution; and measuring the electrical voltage of said test solution at appropriate time points; whereby the concentration of the oxidants or antioxidants in the skin of said subject is determined from the change in the electric potential of said test solution. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
