The study focused on synthesizing PEG-MPOSs with different microstructures by varying the reagents mixing rate, resulting in changes in nanosheet diameter and lattice strain. It was also found that the amount of magnesium and oxygen released from PEG-MPOSs can be tuned by controlling the microstructure.
Delivering adequate oxygen to improve cell survival in a tissue-engineered scaffold is one of the most critical matters by using oxygen-generating biomaterials (OGBs). Magnesium peroxide is one of the OGBs with the ability to release dual magnesium ions and oxygen within liquid environments. In this study, polyethylene glycol coated Magnesium peroxide nanosheets (PEG-MPOSs) with different microstructures were synthesized by the coprecipitation method, and the effect of reagents mixing rate was studied. The results showed diameter of nanosheets and lattice strain were increased by increasing reagents mixing rate, while crystalline sizes were decreased. Moreover, it was found that the amount of magnesium and oxygen released from PEG-MPOSs in 24 days can be tuned by controlling the microstructure, and the fabricated PEG-MPOSs can be used in tissue engineering applications.
