Area of Science:

  • Environmental Science
  • Analytical Chemistry
  • Sensor Technology

Background:

  • In-field water quality monitoring requires deployable, miniaturized analytical tools.
  • Lab-on-a-chip (LOC) technology offers a pathway for standardized, field-based assays.
  • Existing methods often necessitate laboratory analysis, limiting real-time data acquisition.

Purpose of the Study:

  • To present a novel Lab-on-a-chip platform for colorimetric in-field water nutrient monitoring.
  • To demonstrate the feasibility of deploying LOC devices for environmental analysis.
  • To validate the sensor's performance for nitrite detection in natural water bodies.

Main Methods:

  • Development of a miniaturized Lab-on-a-chip platform for colorimetric analysis.
  • Integration of standardized analytical assays for nutrient detection.
  • Field deployment of the sensor prototype for continuous nitrite measurement.
  • Comparison of in-field sensor data with laboratory-analyzed reference samples.

Main Results:

  • The Lab-on-a-chip sensor successfully performed in-field colorimetric measurements of nitrite.
  • The prototype was deployed for 9 hours, collecting measurements every 20 minutes.
  • Data collected in Jade Bay demonstrated the feasibility of real-time nutrient monitoring.
  • Successful correlation between field measurements and laboratory reference samples was achieved.

Conclusions:

  • Lab-on-a-chip technology is suitable for developing deployable instruments for in-field water quality monitoring.
  • Colorimetric assays integrated into LOC platforms can provide accurate and timely nutrient data.
  • The presented sensor prototype demonstrates a viable approach for real-time environmental analysis in aquatic ecosystems.
