“…990 μs, respectively) [177]. These indicators have been widely used as optical oxygen sensors and have been immobilized in various oxygen-permeable polymeric matrices such as polystyrene [104, 178], sol–gels [132, 133], poly(aryl ether ketone) [14], ethyl cellulose, cellulose acetate butyrate and polyvinylchloride [60], styrene-pentafuorostyrene copolymer film [9], and poly(1-trimethylsilyl-1-propyne) [6]. A general disadvantage of these indicators is their rather low photostability.…”

Continuous monitoring of oxygen concentration is of great importance in many different areas of research which range from medical applications to food packaging. In the last three decades, significant progress has been made in the field of optical sensing technology and this review will highlight the one inherent to the development of oxygen indicators. The first section outlines the bioanalytical fields in which optical oxygen sensors have been applied. The second section gives the reader a comprehensive summary of the existing oxygen indicators with a critical highlight on their photophysical and sensing properties. Altogether, this review is meant to give the potential user a guide to select the most suitable oxygen indicator for the particular application of interest.

“…Pt(II)-octaethylpophyrin was initially used in O 2 sensing (Amao, et al, 2002;Lee & Okura, 1997a;Papkovsky, 1995;Papkovsky, et al, 1992), but it has modest photostability and undergoes rapid photobleaching in polymeric matrices (Puklin, et al, 2000). In Pt(II)-tetrakis-(pentafuorophenyl)porphyrin (PtTFPP) dye contain the electronwithdrawing perfluorinated substituents which lower its oxidation potential and improve photostability (Amao, Miyashita, & Okura, 2001;Lee & Okura, 1997b;Puklin, et al, 2000).…”

Intelligent and active packaging technologies have gained attention in recent time due to increased demand by the consumers and manufacturers for sustaining the quality and safety of food products, improved shelf-life as well as real time monitoring of the packaging, storage and handling processes. In this context, phosphorescence based sensors for molecular oxygen (O 2) are important tools for monitoring of packaged products, new product development and optimisation. They allow fast, reversible, real-time and quantitative monitoring of residual O 2 levels in a non-destructive manner, being superior over alternative systems. In this review, we describe the main types of phosphorescent O 2-sensitive materials, fabrication methods and general requirements for sensors for food packaging applications. The main developments and representative examples are provided which illustrate the application of such sensors for monitoring of gaseous and dissolved O 2 in various types of packaged foods and beverages. We also compare commercial O 2 sensing instrumentation and disposable O 2 sensors currently in use.
