2.4. analysis of drug loading and release. fluorescenceThe strength is highly dependent on the molecular state (i.e. free orIn the attached form), so it has been widely used in the studyThe interaction between the fluorophore and quencher.28 - 31 evaluationFe3O4 nanoparticles with digoxin, the interaction of DOX moleculesFluorescence spectrometry. Aqueous suspensionFe3O4 nanoparticles with different amount of digoxin (200, 400, 600, 800,1000 and 1200 g from the stock solution was 1 mg / ml) were added to 1Ml DOX solution (10 g/m L). Mixed culture in roomThe temperature is 15 minutes. Fluorescence spectra of supernatantAfter the recording of magnetic precipitation. StrengthThe supernatant of pure DOX solution is used to determineFe3O4 digoxin loading efficiency of nanoparticles. LoadUse the following formula calculation efficiency (w/w%)
