Example 1

Sensors are built as described in the section entitled ‘Exemplary Glucose Sensor Configuration,’ and include a unitary bioprotective/diffusion resistance domain comprising 2% poly(carboxyl) betaine (pCB). The presence of pCB in the outermost domain of the sensor facilitates surface wetting and speeds polymer rearrangement due to hydration. Faster polymer rearrangement improves sensor performance by reducing sensor drift.
