Electrochemical routes for industrial synthesis

Graphite-coated magnetic FeCo core-shell nanocrystals for few-cells enrichment and detection were reported []. FeCo nanocrystals were synthesized by a chemical vapor deposition method and became water soluble via coating the graphite shell with DSPE-PEG-NH2 and C18-PMH-mPEG polymers, while preventing the magnetic core from oxidation and degradation. These functionalized MNPs were stable and suitable for significant biological applications, such as cell staining, manipulation, cancer cell separation, enrichment and detection. The MNPs -stained cells showed directed motions under external magnetic manipulation.

Recent Advances in the Synthesis and Application of Layered Double Hydroxide (LDH) Nanosheets

Valero demonstrated the synthesis of carbohydrate-coated SPIONs as MRI nanoprobes []. They showed the pH-driven assembly-disassembly natural process that occurred in apoferritin and found it effective for encapsulating maghemite SPIONs of 4 and 6 nm. The SPIONs were further functionalized with two carbohydrates, -acetyl-D-glucosamine and D-mannose vinyl sulfone derivatives. The representative mouse brain images acquired before and 120 s after administration of contrast agents and corresponding regional cerebral blood volume maps (rCBV) maps are shown in Figure . Similar to Endorem, post-contrast images and rCBV maps obtained with Apomaghemite samples depicted very well the space arrangement of cerebral vessels. This study confirmed that Apomaghemite SPIONs could serve as promising contrast agents. Furthermore, the carbohydrate-functionalized Apomaghemite NPs retained their recognition abilities, as demonstrated by the strong affinity with their corresponding carbohydrate-binding lectins.

Ionic liquids for synthesis of inorganic nanomaterials - …

His research mainly focused on using controlled radical polymerization to synthesize a wide range of functional diblock copolymers.

Antibodies are proteins with special Y- shapes. They can specifically recognize and bind to antigens in both the recognition phase (cellular receptors) and during the effectors phase (synthesis and secretion) of humoral immunity. Active targeting by monoclonal antibodies (mAbs) combined with SPION is a promising technology for magnetic resonance imaging.

Ionic liquids are considered as organic solvents with high polarity and a pre-organized solvent structure. Crystalline NPs can be synthesized by using ionic liquid at ambient temperature []. Warner and coworkers have developed magnetic NPs coated with a group of uniform materials based on organic salts by using ion exchange water-in-oil (w/o) microemulsion approach []. These MNPs could potentially be applied in drug delivery, MRI and protein separations.

Water structure science: References 1501 - 1600

Folate-conjugated SPIONs were used for solid tumor targeting in specific magnetic hyperthermia mediators []. The folate surface of maghemite NPs could recognize the folate receptor and was proven by folate receptor expressing cell lines or by radio-labeled folic acid in competitive binding experiments. Water-dispersible sugar-coated SPIONs were designed as magnetic fluid hyperthermia heat mediators and 2 negative contrast agents for MRI []. SPIONs of ca. 16-18 nm had good transverse relaxivity and large heat release upon application of radio frequency (RF) electromagnetic radiation with amplitude and frequency close to the human tolerance limit. The authors claimed that these particles could be used as an efficient bifunctional targeting system for theranostic applications. Initially, the hydrophobic oleic acid stabilized SPIONs synthesized via thermal decomposition method were made water soluble by the displacement of the stabilizing agents, and by covalent grafting of the carbohydrate derivatives via the phosphonate function.
