1. A biosensor for detecting a pathogen comprising:
- a hydrogel functionalized with;
a first affinity molecule with binding specificity for a first pathogen specific marker;
a second affinity molecule with binding specificity for a second pathogen-specific marker; and
a third affinity molecule with binding specificity for a third pathogen-specific marker;
a first indicator capable of producing a first output upon binding of the first affinity molecule with the first pathogen-specific marker;
a second indicator capable of producing a second output upon binding of the second affinity molecule with the second pathogen-specific marker; and
a third indicator capable of producing a third output upon binding of the third affinity molecule with the third pathogen-specific marker, wherein at least one of the first, second, or third outputs comprises an electrical output.

Abstract
The present disclosure provides a biosensor capable of producing an indicator response upon detection of the presence of certain metabolites in a biological sample. The biosensor includes a hydrogel that is functionalized with affinity molecules specific to markers for one or more pathogens. The biosensor also includes a detection system adapted to detect the binding the pathogen-specific markers with their corresponding affinity molecules.
