Area of Science:

  • Analytical Chemistry
  • Environmental Science
  • Sensor Technology

Background:

  • Analyzing cis-diol compounds outside laboratory settings presents significant challenges.
  • Developing portable and rapid detection methods for environmental monitoring is crucial.

Purpose of the Study:

  • To develop a practical, smartphone-based colorimetric system for on-site catechol analysis.
  • To integrate a sensor array with a remote server for real-time data processing and analysis.

Main Methods:

  • A 2x2 colorimetric sensor array using pH indicators and phenylboronic acid was configured.
  • Data analysis involved principal component analysis, hierarchical cluster analysis, and linear discriminant analysis.
  • A smartphone was coupled with a remote server for real-time qualitative and quantitative analysis via partial least squares models.

Main Results:

  • The sensor array successfully distinguished 13 catechols across 6 concentrations.
  • The integrated system achieved 100% accuracy in identifying catechols in a real-world water sample.
  • Concentration prediction accuracy was within 0.706-2.240 standard deviation.

Conclusions:

  • This novel smartphone-based approach offers a practical and accurate solution for on-site catechol detection.
  • The system demonstrates high potential for environmental monitoring and field analysis of cis-diol compounds.
  • Integration with remote servers enhances the capability for real-time data interpretation and decision-making.
