Magnetic Nanoparticles as Contrast Agents for Magnetic Resonance Imaging

A solvent-free synthesis of polyhydroquinolines via Hantzsch multicomponent condensation catalyzed by nanomagnetic-supported sulfonic acid

“…The results listed in Table 2 show that nanomagnetic-supported sulfonic acid is the best catalyst affording the highest yield ( 3 H, we found that product 5a was obtained in yields ranging from 40 to 98 (Table 2, Entries 7-11). Thus, the best amount of catalyst was 0.031 g (8 mol%) ( Table 2, Entry 10).…”

“…The field of nanomagnetic particles is a subset of nanomaterials. The applications for these materials are very diverse such as metal ion separations, 1 enzyme immobilization, 2 magnetic resonance imaging (MRI), 3 drug delivery and catalysis. 4 In chemistry, nanomagnetic catalysts have emerged as one of the most useful heterogeneous catalysts due to their numerous applications in organic synthesis.…”

Magnetic Cobalt and Cobalt Oxide Nanoparticles in Hyperbranched Polyester Polyol Matrix

“…Magnetic nanoparticles exhibit specific physical properties and are of great interest because of their prospective applications in biology and medicine [1][2][3][4][5] for magnetic cell separation [6], magnetically controlled delivery of anticancer drugs [7,8], magnetic resonance imaging (MRI) contrast enhancement [9,10], and hypothermia treatment [11]. Most of these applications require chemically stable, well-dispersed, and uniform sized particles.…”

Recent advances in biological detection with magnetic nanoparticles as a useful tool

“…The progress since 2009 of research on their applications in biological detection is reviewed. There is no doubt that MRI [12][13][14] is a major application of MNPs in biological detection, but no discussion about MRI will appear in this review.…”
