Formation and characterization of biobased magnetic nanoparticles double coated with dextran and chitosan by layer-by-layer deposition

- Biobased particles can be successfully achieved through layer-by-layer deposition.
- The first layer deposited determines the size and stability of the systems.
- Both magnetic nanoparticles presented similar colloidal stability.
- Both polymers are suitable for alternate layer-by-layer coating.
- The double coating process did not shield the magnetization of the nanoparticles.
