A unified approach for investigating chemosensor properties - dynamic characteristics

Area of Science:

• Analytical Chemistry
• Sensor Technology

Background:

• Chemosensors analyze solutions and gases using sensor chemistry, hardware, and software.
• Electrochemical chemosensors are well-established, but research on other transduction modes is emerging.
• Consistent reporting of dynamic properties is lacking, hindering inter-laboratory comparisons.

Purpose of the Study:

• To address the inconsistent reporting of chemosensor dynamic properties.
• To propose standardized methods for characterizing chemosensor performance.
• To enable rationalization of sensor performance based on sensor chemistry.

Main Methods:

• Review of sensor theory and experimental methods for dynamic property determination.
• Discussion of data analysis models for unifying sensor characterization.
• Development of evidence-based recommendations for describing new chemosensors.

Main Results:

• Standardized methods are crucial for excluding drift and activity step change influences.
• A unifying analysis formalism and robust values are necessary for consistent characterization.
• Consistent characterization allows comparison of sensor performance and reveals sensor chemistry insights.

Conclusions:

• Adherence to recommended practices facilitates inter-laboratory comparison of chemosensor performance.
• Standardized characterization enhances understanding of the relationship between sensor chemistry and performance.
• This work is particularly relevant for the advancing field of optical chemosensors.
