Phenol crosslink for sensor membrane
View Patent ↗Embodiments herein provide a membrane that is a product of a phenol crosslinked with one or more compounds containing an allyl group. The phenol may be electropolymerized with the allyl-containing compounds to form the crosslinked polymer. Suitable allyl-containing compounds include allylphenol, allylalcohol, allylamine, and allylcarbamide. A membrane may have one type of allyl-containing compound, or, alternatively, two or more types of compounds. As used in an analyte sensing device, a membrane formed from a crosslinked phenol may provide improved interference exclusion, peroxide response, stability, and/or solvent resistance.
1. An interference exclusion membrane, consisting essentially of phenol crosslinked by one or more of allylalcohol, allylamine, and allylcarbamide.
2. The membrane of claim 1 , wherein the phenol is crosslinked by one of allylalcohol, allylamine, and allylcarbamide.
3. The membrane of claim 2 , consisting essentially of phenol crosslinked by allylalcohol.
4. The membrane of claim 2 , consisting essentially of phenol crosslinked by allylamine.
5. The membrane of claim 2 , consisting essentially of phenol crosslinked by allylcarbamide.
6. The membrane of claim 1 , wherein the phenol is crosslinked by two of allylalcohol, allylamine, and allylcarbamide.
7. An analyte sensor, comprising:
the interference exclusion membrane of claim 1 ; and
an electrically active electrode surface.
8. The analyte sensor of claim 7 , wherein the interference exclusion membrane is disposed on the electrically active electrode surface.
9. The analyte sensor of claim 8 , further comprising an enzyme layer disposed on the interference exclusion membrane.
10. The analyte sensor of claim 7 , further comprising an enzyme layer disposed on the electrically active electrode surface, wherein the interference exclusion membrane is disposed on the enzyme layer.
11. The analyte sensor of claim 7 , wherein the interference exclusion membrane is configured to provide interference exclusion, peroxide response, stability, and/or solvent resistance.
