Abstract
The inventive concepts disclosed herein are generally directed to a sensor array device that has a prolonged shelf life but requires only a minimal amount of sample volume in order to test two or more analytes concurrently. In order to ensure the sensor array has a sufficient shelf life, anti-diffusion regions are positioned among the reaction wells in order to slow the processes of diffusion. The use of anti-diffusion regions, as described herein, can be used to optimize the number of sensors that can be fit into a sensor array designed for reduced sample liquid volumes (e.g., less than 100 μL) as well as extending the test strip's shelf life.
