“…Parvin et al, for instance, reported the surfaceinitiated atom transfer radical polymerization (SI-ATRP) of Nmethacryloxysuccinimide (NMAS) and showed that the resulting brushes can be post-modified in near quantitative yield with various n-alkylamines. 16,17 Similar results have been obtained in studies that have explored the reactivity of polymer brushes generated from N-methacryoyl-b-alanine-N 0 -oxysuccinimide ester (MAC 2 AE) 18 and N-hydroxysuccinimide 4-vinyl benzoate (NHS4VB) 19,20 to various primary amines. In spite of their successful use as evidenced by the examples cited above, the use of succinimide based active ester monomers still suffers from several limitations.…”

“…The surface-initiated ATRP reaction of SucMA from the nanoparticle surface was carried out in a two-step reaction, as reported elsewhere [32]. In brief, first the ATRP initiator 2-bromoisobutyric acid (BrIBA)-coated iron oxide nanoparticles (nP-BrIBA) were prepared using a ligand-exchange reaction between as-prepared oleic acid, oleyl amine-stabilized nanoparticles and BrIBA (Scheme 1, step 2).…”

“…We applied surfaceinitiated atom transfer radical polymerization (ATRP) of Nhydroxysuccinimide methacrylate (SucMA) to synthesize polysuccinimide methacrylate-coated iron oxide nanoparticles (nPpSucMA). Recently, we have reported surface-initiated ATRP of SucMA from iron oxide nanoparticles [32]. The pSucMA, applied onto the nanoparticle surface, can act as a reactive polymer shell.…”

“…In this early case, the coating generated was polystyrene. However, more interesting coatings such as activated esters, antibacterial quaternary amines, and poly‐2‐(dimethylamino)ethyl methacrylate (capable of gene delivery) have also been prepared. The Kang group has combined ATRP and click chemistry to make folic acid‐functionalized MNPs that target tumor cells while maintaining low immuno‐recognition .…”

3761wileyonlinelibrary.com single magnetic domain of the particle. The mean time between fl ips (the Neel relaxation time) depends on temperature. For many practical applications, the time of the experiment is orders of magnitude longer than the Neel relaxation time, so that the average particle magnetization is zero. The random fl ipping depends on temperature. At a given (generally low) temperature (termed the blocking temperature) the Neel relaxation time is the same as the characteristic time of the experiment, and thus above the blocking temperature the nanoparticle is superparamagnetic. The blocking temperature depends on the particle composition, size and shape. For example, for a 10 nm diameter spherical Fe 3 O 4 nanoparticle in a typical laboratory experiment the blocking temperature is far below 200 K, [ 2 ] thus the particles are superparamagnetic for most intended applications. Very low toxicity, low cost, simple and well-reproducible synthesis render iron oxide nanoparticles the most extensively used superparamagnetic nanomaterial.The response of a superparamagnetic particle to a magnetic fi eld and the experimental timeframe required for loss of the average magnetization has been intensively explored in numerous examples of stimuli-responsive nanostructures. The major advantage of materials based on magnetic particles is that the mechanism of response does not interfere with many other properties of the materials and that the magnetic fi eld (with a practical range on the order of 1 Tesla or less) is noninvasive for living organisms. The latter is a critical aspect for biomedical and other applications involving live species. The number of annual publications that utilize superparamagnetic nanoparticles is >1000 and rising. The rapid increase of interest in magnetic nanoparticles (MNPs) can be attributed to studies on magnetic imaging and drug delivery systems which built upon older research involving ferrofl uids. A number of excellent reviews have recently been published on the synthesis and applications of MNPs, [ 3 ] surface functionalization, [ 4 ] their biomedical applications, [ 3b , 5 ] applications in recyclable catalysts, [ 6 ] MNP toxicity, [ 7 ] and many others. [ 8 ] This review is focused on the surface functionalization of MNPs that can be used to either (a) generate nanostructured materials or to (b) add responsive properties to the materials. The goal of this review is to assemble the most practical and important information for material scientists working in the area of nanostructured materials with a focus on assembly using bottom-up methods. Magnetic fi eld induced forces can be tuned by the regulation of the magnetic fi eld direction, strength and gradient, which provide a large toolbox for the manipulation of nanoscale forces. [ 9 ] The structure of this article is as Magnetic fi eld imaging in living specimens with magnetic nanoparticles as contrasting agents has attracted signifi cant interest in the rapidly developing fi eld of nanomedicine. Developments in this fi eld ...
