The limit of detection (LOD) in electrochemical sensors refers to the lowest concentration of an analyte that can be reliably detected. Typically, LOD is influenced by factors such as the sensor's sensitivity, the baseline noise level, and the signal-to-noise ratio. Achieving a lower LOD often requires optimizing these factors, ensuring high sensitivity and minimizing interference. Understanding these elements can lead to more precise and accurate measurements, crucial for various applications.
