Iron oxide nanoparticle-stabilized Pickering emulsion-templated porous scaffolds loaded with polyunsaturated fatty acids (PUFAs) for bone tissue engineering.

Dietary intake of ω-3-polyunsaturated fatty acids (PUFAs) can significantly improve the expression levels of alkaline phosphatase (ALP) and osteocalcin. However, PUFAs are hydrophobic and highly sensitive to temperature, oxygen concentration, pH, and ionic strength. Hence, it is challenging to use PUFAs as bioactive compounds for bone tissue engineering.
