Oxygen releasing strategy Instrumentation/Measuring method References
PLGA films with sodium per carbonate Observed the volume of water displaced by the oxygen gas generated from the films. Used chemical equation for decomposition of sodium per carbonate and the ideal gas law. [39]
PLGA/Calcium peroxide based scaffold BloodGas Analyzer (EasyBloodGas, Medica) [11]
Hydrogen peroxide base functionalized micro-system Concentration was recorded using a portable oxygen meter (Thermo Orion Series, 3 Star) through electrode of the meter (Thermo, ORION 081010 MD). [12,13]
