Superparamagnetic microsphere-assisted fluoroimmunoassay for rapid assessment of acute myocardial infarction

Modification and Characterization of Fe3O4 Nanoparticles for Use in Adsorption of Alkaloids

“…The black precipitate was collected by magnetic decantation and washed with deionized water repeatedly until the washings were neutral. The obtained black precipitate was then dried over vacuum at 40 °C overnight, which could be used for XRD measurement [ 14 , 15 ].…”

Modification of bimetal Zn/ Mg MOF with nanoparticles Fe3O4 and Fe3O4@SiO2, investigation of the peroxidase-like activity of these compounds by calorimetry and fluorimetry methods

“…The dark sediment was assembled by magnetic and washed with deionized water/ethanol with (5:1v/v) three-time. The received dark residue dried over a vacuum at 30 °C overnight [ [38] , [52] ].…”

“…The placement of secondary metal ions in the crystal lattices of metal oxides increases the optical, electrical, and magnetic properties by increasing the porosity and adsorption sites [ 35 ]. Until now, many studies have been done on the catalytic activity of Zn MOFs [ [36] , [37] , [38] ]. Nanoparticle Fe 3 O 4 [ 39 ] inherently, and the composites obtained from Fe 3 O 4 and MOFs have peroxidase-like active [ [39] , [40] , [41] , [42] ].…”

Fe3O4 and bimetal–organic framework Zn/Mg composite peroxide‐like catalyze luminol chemiluminescence for specific measurement of atropine in Datura plant

“…The dark sediment was assembled by magnetic and washed with deionized water/ethanol with (5:1v/v) three-time. The received dark residue dried over a vacuum at 30°C overnight [20], [21] Preparation of Fe 3 O 4 @SiO 2 Modi cation of Fe 3 O 4 Nanoparticles with TEOS: 30mg of Fe 3 O 4 synthesized acidized by HCl (0.1 mol/L) ultrasonic for 20 min. Using a magnet, discard the supernatant; residual was washed with DDW three times, then added DDW/ethanol (60:40 v/v) to sample that MNPs suspension.…”
