| description | AIM: To prepare a folic acid-magnetic dual target, adriamycin(ADM)-loaded phase change liposome nanoparticles(FA-PFH-Fe3O4@ADM), and observe its ability to target retinoblastoma Y79 cells and its three-mode imaging ability of in vitro ultrasound/photoacoustic/magnetic resonance.METHODS: FA-PFH-Fe3O4@ADM was prepared by the double emulsification method, and its basic characteristics were tested. Test the cellular safety of nanoparticles. Observe the heating phenomenon and phase transition of nanoparticles under 808nm laser. Y79 cells in logarithmic growth phase were divided into four groups. The non-targeted group and the single magnetic target group were added with PFH-Fe3O4@ADM nanoparticles(0.625mg/mL). The single folic acid target group and folic acid-magnetic dual target group were added with FA-PFH-Fe3O4@ADM nanoparticles(0.625mg/mL). A 4T magnet was placed at the side of the orifice plate of the single magnetic target group and the folic acid-magnetic double target group to evaluate the targeting ability of nanoparticles on Y79 cells. In addition, the ability of FA-PFH-Fe3O4@ADM nanoparticles ultrasound/photoacoustic/magnetic resonance three-mode imaging in vitro was observed.RESULT: FA-PFH-Fe3O4@ADM nanoparticles were successfully prepared with uniform distribution and uniform spherical structure. The average particle size of nanoparticles was 338.6±2.20 nm. ADM and Fe3O4 were successfully loaded, with an encapsulation efficiency of(41.76±4.12)% and(59.06±13.63)%, respectively. Nanoparticles had good paramagnetic properties and showed no obvious toxicity to Y79 cells. The phagocytic rate of the folic acid-magnetic dual target group(86.19±0.55)% was significantly higher than that of the single folate target group(43.36±5.91)% and single magnetic target group [(28.58±3.23)%, P<0.05]. The FA-PFH-Fe3O4@ADM nanoparticles rapidly heat up and undergo phase transitions under the action of laser. Moreover, they can enhance ultrasound and photoacoustic imaging, and they can negatively enhance magnetic resonance imaging in T2 mode.CONCLUSION: FA-PFH-Fe3O4@ADM nanoparticles have been successfully prepared in this study, which not only has a good targeting effect on retinoblastoma Y79 cells, but also can achieve ultrasound/photoacoustic/magnetic resonance three-mode imaging in vitro. |
