Apparatus For Non-invasive Skin Sampling And Testing

Abstract

An apparatus for the non-invasive sampling of skin is provided which allows testing of a skin sample directly on the apparatus. In various embodiments the apparatus can be used to analyze specific components in the skin sample such as, for example, but not limited to, skin cholesterol, disease causing organisms such as fungi, skin contaminants such as chemical spill components, inflammatory mediators, allergens, and toxins. In various embodiments, the device has an area of adhesive tape used for skin sampling that is attached to a substrate backing layer. The adhesive can have a removable protective liner to protect the adhesive prior to use in sampling. Skin samples are obtained by removing the protective liner from the sampling area and then pressing the adhesive to the skin. A second protective liner material can be removably attached to a second adhesive tape area that is also attached to the substrate backing layer. For various embodiments, this second area can have one or more holes punched through both the tape and the backing layer. The sampling area can then be folded over such that the sampling area and its attendant skin sample is stuck to the second tape area. This leaves a skin sample exposed on the bottom of the one or more holes in the apparatus. These holes form wells with a fixed cross-sectional area and that have a skin sample on the bottom surface. The skin sample, of fixed area, at the bottom of the wells can then be probed with reagents that can be added to the wells.
