An electrochemical sensor system comprises an electrochemical sensor and a hydrogel composition. The electrochemical sensor has at least a counter electrode and a working electrode. The hydrogel composition contacts the working electrode. The hydrogel composition comprises a first monomer, a second monomer, a cross-linking agent, and a solvent. The first monomer has hydrophilic characteristics. The second monomer has hydrophobic characteristics. The ratio of the first monomer to the second monomer is from about 0.1:99.9 to about 99.9:0.1.
