Abstract
Briefly, a sensor for a continuous biological monitor is provided that has a working electrode with an enhanced enzyme layer that in one embodiment is made by mixing an aqueous polyurethane emulsion with an acrylic polyol emulsion to make a base emulsion. An enzyme is added to the base emulsion, which is applied to the working electrode and cured. Optionally, other additives can be added to the base emulsion prior to application, such as hydrophiles, cross linkers, adding imodeoesters, hydroxysuccimide, carboldilite, melamines, epoxies, benzoyl peroxide or dicumyl peroxide.
Claims11
A method of making an enzyme membrane for a working electrode of a continuous biological monitor, the method comprising:
- making an aqueous polyurethane emulsion;
- making an acrylic polyol emulsion;
- mixing the polyurethane emulsion and the acrylic polyol emulsion to make a base emulsion;
- adding an enzyme to the base emulsion to create an enzyme/base emulsion dispersion, the enzyme being selected according to a biological function to be monitored;
- applying the enzyme/base emulsion dispersion to the working electrode;
- and
- curing the applied enzyme/base emulsion dispersion.
