**4.3 Reproducibility**

Reproducibility is the capacity of the biosensor to deliver similar results under the same analysis conditions. The precise and accurate transducer and biosensor electronics define reproducibility. After a sample is checked more than once, precision denotes the sensor's ability to consistently produce results, whereas capacity deals

with accuracy to provide a mean value that is close to the right value. The inference made from a biosensor's response is particularly robust and reliable while there are repeatable signals [10].

### **4.4 Linearity**

The term linearity in biosensors means a characteristic that shows the accuracy of the measured response for a set of measurements to a straight line with various analyte concentrations in the mathematical equation y = mc, where m is the sensitivity of the biosensor, c is the analyte concentration, and y is the signal at output. Both the range of analyte concentrations and the biosensor's resolution being tested impacted the biosensor's linearity. The biosensor resolution is the lowest change in concentration of an analyte that is required to alter the biosensor's response [10].

### **4.5 Stability**

The word "linear range," which is linked to linearity, denotes the analyte concentration range for which the response of the biosensor differs linearly with the change in concentration.

By considering application, a strong resolution may be necessary because most biosensor applications require analyte concentration monitoring and not only analyte detection across a wide working range [10].
