“…Also, Pluronic F–127 has been used for numerous applications such as for the preparation of micelles as a drug delivery system for photodynamic therapy [ 28 ] or nanoparticles as antioxidant carriers to stabilize polymers [ 29 ]. Besides, as a non-toxic co-polymer, Pluronic F–127 was widely used for the encapsulation of living cells and in other biomaterials research [ 30 ]. So far, there have been several gel dosimeters for 3D radiotherapy developed on the basis of Pluronic F–127 [ 25 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ].…”

This paper presents the results of research on the Fricke–XO–Pluronic F–127 dosimeter. It consists of a Fricke dosimetric solution and xylenol orange (XO), which are embedded in a matrix of poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide) (Pluronic F–127). Upon irradiation, Fe+2 ions transform into Fe+3, forming a colored complex with XO ([XO-Fe]+3). The color intensity is related to the dose absorbed. The optimal composition, storage conditions, and radiation-induced performance of the Fricke–XO–Pluronic F–127 dosimeter were investigated. The optimal composition was found to be 1 mM FAS, 50 mM sulfuric acid (H2SO4), 0.165 mM XO in 25% Pluronic F–127. The basic features of this dosimeter are discussed, such as dose sensitivity, linear and dynamic dose range, stability before and after irradiation, storage conditions, dose response for irradiation with 6 and 15 MV photons, and batch-to-batch reproducibility. The obtained results showed a certain potential of the Fricke–XO–Pluronic F–127 for radiotherapy dosimetry.

“…Moreover, many commercially used printing pastes do not form a transparent film on the textile (cloudiness and yellowing occur), which may cause readout errors. Pluronic F-127, on the other hand, is a copolymer composed of poly(propylene oxide) core and surrounding poly(ethylene oxide) blocks, which, if used as a gel matrix in radiochromic hydrogels, provides a high degree of transparency and colourlessness [ 25 , 26 , 27 ], which completely eliminates this problem. Furthermore, Pluronic F-127 is a nontoxic copolymer approved by the US Food and Drug Administration (FDA) [ 25 ], which is another reason for replacing the printing paste containing environmentally harmful chemical compounds.…”

“…So far, radiochromic hydrogels have been widely studied as dosimeters for high-resolution three-dimensional UV or ionising radiation dose distribution measurements. For this purpose, several dosimeter compositions have been tested, such as TTC-Pluronic F-127, LMG-Pluronic F-127 [ 25 , 26 ], NBT-Pluronic F-127 [ 29 ] and LCV-Pluronic F-127 [ 30 , 31 ]. In this work, we present another possibility of using such radiochromic hydrogels and, simultaneously, a new approach to the preparation of UV-sensitive textile-based sensors.…”

This work reports on the surface-modified woven fabrics for use as UV radiation sensors. The cotton and polyamide fabrics were printed with radiochromic hydrogels using a screen-printing method. The hydrogels used as a printing paste were composed of water, poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide) (Pluronic F-127) as a gel matrix and nitro blue tetrazolium chloride as a radiation-sensitive compound. The development of the hydrogels’ colour occurs after exposure to UV radiation and its intensity increases with increasing absorbed dose. The features of the NBT-Pluronic F-127 radiochromic hydrogels and the fabrics printed with the hydrogels were examined using UV-Vis and reflectance spectrophotometry as well as scanning electron microscopy (SEM). The effects of NBT concentration and UV radiation type (UVA, UVB, UVC) on dose responses of the hydrogels and printed fabrics were also examined. The results obtained reveal that the fabrics printed with NBT-Pluronic F-127 hydrogels can be potentially useful as UV radiation sensors.

“…Optical computed tomography is the readout method in this case. Examples of such dosimeters include PRESAGE® plastic [34][35], gel dosimeters based on leuco-dyes and gelatine [36][37][38], and leuco-dyes or tetrazolium salts and Pluronic F-127 [39][40][41][42].…”
