Abstract
Described herein are devices for collecting and analyzing a fluid sample, the devices comprising a fluid-collecting porous material comprising at least one hydrophilic porous layer and one or more sensors adapted to provide a response to the presence of an analyte. The detectors are useful for collecting and analyzing a very small volume of sample and may include features that facilitate and direct flow of the sample through porous material.
Claims30
A detector comprising:
- a first layer having a first side and a second side opposite the first side,
- wherein the first layer comprises a synthetic porous membrane having a first average pore size,
- wherein at least a portion of the first layer is hydrophilic, and
- wherein the first layer is configured to conform to the skin;
- a second layer having a first side and a second side opposite the first side,
- wherein the second layer is coupled to the first layer such that at least a portion of the first side of the second layer is directly adjacent to at least a portion of the second side of the first layer,
- wherein the second layer comprises a synthetic porous membrane having a second average pore size that is smaller than the first average pore size, and
- wherein at least a portion of the second layer is hydrophilic;
- and
- at least one sensor configured to detect the an analyte in a sample collected on skin of a subject,
- wherein the at least one sensor is mounted to at least one of (a) the first layer, or (b) the second layer.
