1. An ostomy wafer comprising
a chromatic nanofiber biosensor responsive to the presence of at least one pathogenic biomarker;
a unitary adhesive layer provided with a proximal surface in an axial direction configured to face a user during use;
a backing layer provided with a distal surface in an axial direction configured to face away from said user during use;
an opening having an inner radial boundary defining a stoma receiving opening;
an outer radial boundary defining a peripheral edge of said ostomy wafer;
wherein, said biosensor is positioned on said proximal surface between said inner radial boundary defining said stoma receiving opening and said outer radial boundary defining the peripheral edge of said ostomy wafer to provide a boundary area on said adhesive layer configured to contact peristomal skin,
wherein, said biosensor is embedded within said adhesive layer of said ostomy wafer so that the wafer coupled with the biosensor can be applied in a single step with said biosensor positioned to be around the stoma and in direct contact with the peristomal skin, and
wherein, said biosensor is adapted to provide a visual color-change indication at a critical threshold of presence when said at least one pathogenic biomarker is exposed to the biosensor.
