Case Study

Synthesis of Fluorescent Brightener 28-Coated Fe3O4 Nanoparticles

Tegafaw T, et al. Journal of Nanoscience and Nanotechnology, 2016, 16(10), 10986-10990.

Fe3O4 nanoparticles are coated with fluorescent brightener agent 28 (FB28), which exhibits strong photoluminescence (PL) emission at 435 nm and has potential for biomedical applications. Furthermore, they also provided confocal images of strong fluorescence in the green and blue regions due to the nanoparticles being coated with FB 28.
Synthesis process of FB28-coated Fe3O4 nanoparticles
· Firstly, almost monodispersed Fe3O4 nanoparticles were produced in the aqueous phase from FeCl2·4H2O.
· FB 28 (0.2 mmol) was dissolved in triply distilled water (150 mL) in a 300 mL three-necked flask at room temperature under an argon flow. The mixture was mechanically stirred until the FB 28 was completely dissolved.
· The synthesized nanoparticles were then added to the FB 28 solution and the solution was mechanically stirred for 8 h. The solution containing the product was poured into a beaker containing triply distilled water (400 mL). The solution was stirred for 10 min and stored to allow the product nanoparticles to settle to the bottom of the beaker.
