Bone tissue engineering (BTE) utilizing biomaterial scaffolds and human mesenchymal stem cells (hMSCs) is a promising approach for the treatment of bone defects. The quality of engineered tissue is crucially affected by numerous parameters including cell density and the oxygen supply. In this study, a novel oxygen-imaging sensor was introduced to monitor the oxygen distribution in three dimensi...

A class of core-shell nanoparticles possessing a layer of biocompatible shell and hydrophobic core with embedded oxygen-sensitive platinum-porphyrin (PtTFPP) dyes is developed via a radical-initiated microemulsion co-polymerization strategy. The influences of host matrices and the PtTFPP incorporation manner on the photophysical properties and the oxygen-sensing performance of the nanoparticles...

Oxygen is one of Earth’s vital elements, and its accurate measurement crucial in numerous scientific medical applications. Photonic-based sensors have recently become the subject great attention for oxygen measurements due to their highly promising characteristics. These include lack requirement repetitive calibrations replacement parts, being contactless, accuracy, fast response, potential fab...

Oxygen sensors play a vital role in ensuring the safety of employees and users at National High Magnetic Field Laboratory. While most oxygen have accurate linear responses nitrogen/argon environments, studies highlighted phenomenon helium-air mixtures with certain types sensors. A controlled experiment was performed to observe behavior two sensors: orifice membrane. The sensor showed large devi...

A screen-printed dissolved oxygen sensor was fabricated using cerium oxide-supported silver catalyst and polydimethylsiloxane (PDMS) film. A PDMS film of 3 µm thickness showed good permeability for oxygen and impermeability for hydrogen peroxide. The calibration curve has shown a linear relationship with a correlation coefficient of 0.996 for the dissolved oxygen concentration. The sensitivi...
