Background:

Traditional electrochemical oxygen sensors can be expensive and complex.
Optical sensing methods offer potential for low-cost, portable alternatives.
Time-resolved fluorescence is a sensitive technique for detecting analytes.

Purpose of the Study:

To describe a new, simple, low-cost technique for fabricating a portable oxygen sensor.
To utilize time-resolved fluorescence with a platinum-based dye for oxygen sensing.
To develop a cost-effective alternative to existing oxygen sensor technologies.

Main Methods:

Fabrication of a sensing film using platinum meso-tetra (pentfluorophenyl) porphyrin (PtTFPP) embedded in a polymer matrix.
Measurement of fluorescence lifetimes (τ) of the sensing film under 100% nitrogen (τ₀) and 100% oxygen (τ₁₀₀).
Development of a preparation procedure for reliable coating of photodiodes with the sensor film.

Main Results:

The PtTFPP-doped oxygen sensor demonstrated a sensitivity ratio (τ₀/τ₁₀₀) of 2.2 across the 0%-100% oxygen range.
The developed sensor is portable, low-cost, and features simple signal processing.
The sensor fabrication method ensures repetitive and reliable device performance.

Conclusions:

A portable, low-cost time-resolved optical oxygen sensor based on PtTFPP has been successfully developed.
