“…Oxygen (O 2 ) is another gas that researchers have detected using MOFs. X. Yang et al in [79] proposed an oxygen gas optrode by forming a fluorophore doped sensing film. Organic silicate gels and plasticized cellulose acetate were chosen as sensing film and they were deposited inside the microholes of an SC-PCF.…”

Since the first publications related to microstructured optical fibers (MOFs), the development of optical fiber sensors (OFS) based on them has attracted the interest of many research groups because of the market niches that can take advantage of their specific features. Due to their unique structure based on a certain distribution of air holes, MOFs are especially useful for sensing applications: on one hand, the increased coupling of guided modes into the cladding or the holes enhances significantly the interaction with sensing films deposited there; on the other hand, MOF air holes enhance the direct interaction between the light and the analytes that get into in these cavities. Consequently, the sensitivity when detecting liquids, gasses or volatile organic compounds (VOCs) is significantly improved. This paper is focused on the reported sensors that have been developed with MOFs which are applied to detection of gases and VOCs, highlighting the advantages that this type of fiber offers.

“…Recently, an inline sensor based in two pieces of an HC-PBF with laser-drilled lateral micro-channels for gas access was reported [175], showing the ability to quantitatively measure gas mixtures. An oxygen gas sensor was also reported by forming fluorophore-doped sensing film in the array microholes of a solid core PCF, with a sensitivity of 10.8 (defined as I 0 /I 100 ) and quick response time ∼50 ms [176].…”

Photonic crystal fibers are a kind of fiber optics that present a diversity of new and improved features beyond what conventional optical fibers can offer. Due to their unique geometric structure, photonic crystal fibers present special properties and capabilities that lead to an outstanding potential for sensing applications. A review of photonic crystal fiber sensors is presented. Two different groups of sensors are detailed separately: physical and biochemical sensors, based on the sensor measured parameter. Several sensors have been reported until the date, and more are expected to be developed due to the remarkable characteristics such fibers can offer.

“…Cellulose acetate (CA), the most abundant biobased material, has attracted the interest of scientists as an oxygen-sensitive matrix due to its high stability, simple molding process and easy modification [ 7 , 8 , 9 ]. However, its sensitivity to oxygen is still inadequate, because of its poor oxygen permeability [ 10 ].…”

Real-time monitoring of dissolved oxygen (DO) and pH is of great significance for understanding cellular metabolism. Herein, a dual optical pH/O2 sensing membrane was prepared by the electrospinning method. Cellulose acetate (CA) and poly(ε-caprolactone) (PCL) nanofiber membrane blended with platinum (II)-5,10,15,20-tetrakis-(2,3,4,5,6-pentafluorophenyl)-porphyrin (PtTFPP) was used as the DO sensing matrix, upon which electrospun nanofiber membrane of chitosan (CS) coupled with fluorescein 5-isothiocyanate (FITC) was used as the pH sensing matrix. The electrospun sensing film prepared from biocompatible biomaterials presented good response to a wide range of DO concentrations and physiological pH. We used it to monitor the exracellular acidification and oxygen consumption levels of cells and bacteria. This sensing film can provide a luminescence signal change as the DO and pH change in the growth microenvironment. Due to its advantages of good biocompatibility and high stability, we believe that the dual functional film has a high value in the field of biotechnology research.
