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.
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; anda third affinity molecule with bin
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; anda 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; anda 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. 2. The biosensor in claim 1, wherein the biosensor comprises an adhesive configured to affix the biosensor to a patient. 3. The biosensor recited in claim 1, wherein the first, second, and third pathogen-specific markers are metabolic products of the pathogen. 4. The biosensor recited in claim 1, wherein at least one of the first, second, or third outputs comprises a change in electrical impedance of the hydrogel triggered by binding of the respective first, second, or third pathogen-specific marker. 5. The biosensor recited in claim 1, wherein at least one of the first, second, or third pathogen-specific markers is specific to helicobacter pylori. 6. The biosensor recited in claim 1, wherein the first, second, and third pathogen-specific markers are part of a secretome of the pathogen. 7. The biosensor recited in claim 6, wherein the first, second, and third pathogen-specific markers are part of the secretome of Plasmodium falciparum. 8. The biosensor recited in claim 6, wherein the first, second, and third pathogen-specific markers comprise proteins having the pexel/vacuolar transport signal. 9. The biosensor recited in claim 1, wherein at least one of the first, second, or third affinity molecules is an antibody. 10. The biosensor recited in claim 1, wherein the first affinity molecule is disposed on a first region of the hydrogel, the second affinity molecule is disposed on a second region of the hydrogel, and a third affinity molecule is disposed on a third region of the hydrogel. 11. The biosensor recited in claim 1, wherein the hydrogel comprises 2-hydroxyethyl methacrylate or N-Isopropylacrylamide. 12. The biosensor recited in claim 1, wherein the hydrogel comprises a mucoadhesive. 13. A system 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; anda 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;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; anda monitor operatively coupled to the first indicator, the second indicator, and the third indicator, wherein the monitor is configured to receive the first output, the second output, and the third output and perform an operation to determine if the pathogen is present in a biological sample. 14. The system recited in claim 13, comprising an alarm that is adapted to be triggered upon detection of the pathogen. 15. The system recited in claim 13, wherein the hydrogel is disposed on a surface of the biosensor adapted to directly contact a patient.
