Nanoparticle (NP) type | Chemical form of ω-3 PUFA used | NP size (nm) | EE (%) | Cargo molecule | Zeta potential (−mV) | Function of the NP | Experimental model | Mechanisms involved in the NP effects | Reference |
---|---|---|---|---|---|---|---|---|---|
α-Tocopheryl linoleate-based SLN | ALA-free fatty acid | 181 | 77 | ALA | ND | To improve the delivery and stability of ALA | Human C32 melanoma cells in vitro | Enhanced antioxidant efficiency*; enhanced cytotoxicity# | 91 |
Resveratrol-based SLN | ALA- or DHA free fatty acids | 842 (DHA-containing SLN); 1000 (ALA-containing SLN) | 77 (ALA); 100 (DHA) | DHA or ALA | ND | To protect ω-3 PUFA from degradation and to increase their incorporation in cancer cells | Human HT29 and HCT116 colon cancer cells in vitro | Increased ω-3 PUFA incorporation in tumor cells; increased cancer cell growth inhibition; reduced cancer cell proliferation§ | 92 |
