Synthesis and magnetostructural studies of amine functionalized superparamagnetic iron oxide nanoparticles

Abstract

Superparamagnetic iron oxide nanoparticles are synthesized through the co precipitation method by using the new generation base diisopropylamine (DIPA) which electrostatically complexes with the iron ions, reduces them and subsequently caps the nanoparticles.

“…The average crystallite size of the particles was calculated by using the most intense peak at 400. 25 In the XRD spectrum of M3D-PAA-CCN, along with the Fe 3 O 4 peaks a new peak (200) at 21.3 yet again conrmed the presence of CCN. 55,56 The elemental compositions of M3D and M3D-PAA-CCN were obtained from both XPS and EDX (ESI, Fig.…”

“…Magnetic iron oxide (Fe 3 O 4 ) nanoparticles were prepared by following an easy and widely used chemical co-precipitation method. [25][26][27] Firstly, an iron salt solution was prepared by adding 0.005 mol of FeCl 3 (1.351 g) and 0.0025 mol of FeCl 2 (0.497 g) to 50 mL of deoxygenated ultrapure water so that the ratio of Fe 3+ to Fe 2+ was 2. Then 20 mL of NaOH (1.5 M) was rapidly poured into the iron salt solution under vigorous magnetic stirring at room temperature under N 2 atmosphere.…”

Synthesis, Functionalization, and Design of Magnetic Nanoparticles for Theranostic Applications

“…[67] Salunkhe produced superparamagnetic iron oxide nanoparticles from ferrous chloride and ferric chloride salts by applying a new generation base diisopropylamine, which electrostatically complexes with iron ions, reduces them and subsequently caps the nanoparticle. [68] A comprehensive study was performed by Hauser et al [69] to investigate the chemical properties of dextran coated iron oxide nanoparticles via four variations on the coprecipitation method. The time of the addition of dextran into the reaction mixture was the varying parameter Schemes of different types of hydrolytic and non-hydrolytic wet-chemistry routes for the synthesis of nanoparticles.…”

“…RGD peptides were also employed to specifically target integrin (α v β 3 ). In a recent study oleic acid coated iron oxide nanoparticles were labeled with 68 Ga and DOTA respectively as radionuclide and chelating agents for dual PET/MR imaging of prostate. [785] Additionally, they were decorated with glutamate-urea-lysine targeting ligands to increase their affinity for prostate-specific membrane antigen (PSMA) (Figure 46b).…”

Magnetic Detection Structure for Lab-on-Chip Applications Based on the Frequency Mixing Technique

“…Furthermore, practical aspects, such as heating and parasitic effects that can cause substantial damage to the biological samples, were considered. Heating can cause both a decrease and fluctuation in the detected signal since the magnetization of the SPN is inversely proportional to the temperature [ 24 ]. Consequently, compromises should be considered for this miniaturized system.…”
