This study introduces a novel pin printing and sol-gel method for quickly creating reusable chemical sensor arrays. This technique enables simultaneous detection of multiple analytes, like oxygen (O2) and pH, in aqueous samples.

Area of Science:

  • Chemical sensor technology
  • Materials science
  • Analytical chemistry

Background:

  • Developing reusable multianalyte chemical sensor arrays is crucial for efficient simultaneous detection.
  • Existing methods for producing sensor elements can be slow and lack scalability.

Purpose of the Study:

  • To demonstrate a new, rapid method for producing micrometer-scale sensor elements for reusable multianalyte chemical sensor arrays.
  • To form discrete xerogel-based microsensors on a planar substrate using pin printing and sol-gel processing.
  • To create sensor arrays capable of simultaneously determining oxygen (O2) and pH in aqueous samples.

Main Methods:

  • Utilized pin printing technology combined with sol-gel processing to create discrete xerogel-based microsensors.
  • Formed O2- and pH-responsive sensing elements into arrays on a planar substrate.

  • Characterized sensor element size (approx. 100 microm diameter, 1-2 microm thick) and production rate (approx. one sensor/sec/pin).

    • Main Results:

    • Achieved reproducible sensor element response within a calibrated array (5% element-to-element variability).
    • Demonstrated high sensor element reproducibility (3% short-term, 6% long-term).
    • Reported array-to-array response reproducibility of 11%.

    Conclusions:

    • The pin printing and sol-gel methodology offers a rapid and efficient approach for fabricating reusable sensor arrays.
    • This technique shows significant potential for the simultaneous detection of multiple analytes.
    • The developed method facilitates the creation of ensembles of sensor arrays for diverse analytical applications.
