“…The AuNP core had a diameter of 4.5 ± 2.3 nm, as measured by transmission electron microscopy (TEM) (Supporting Information). Further, the copolymers (AuNP‐ co ‐PMMA) of MMA with small amounts (2 wt%) of AuNP 3 were made by radical polymerization using azobisisobutyronitrile (AIBN) as initiator, according to our previously published procedure . The reason for copolymerization with MMA will be explained below.…”

“…The authors have reported an important observation that the particles synthesized are similar in size and stability to those obtained by the conventional citrate reduction method. This may be due to the fact that sodium acrylate structure and properties in water resemble to the properties of citric acid or sodium salt of citric acid …”

“…This may be due to the fact that sodium acrylate structure and properties in water resemble to the properties of citric acid or sodium salt of citric acid. [ 70 ] Vinyl-functionalized gold nanoparticles (AuNP) were prepared by surface poly-merization of vinyl functionalized ligands called 4-vinylbenzylthiol (and/or the corresponding symmetrical disulphide of it) as shown in the Figure 5 . The vinyl functionalized gold nanoparticles were then used as comonomers for the free radical copolymerization with methyl methacrylate (MMA).…”

Monomers bearing functional groups that can get chemisorbed on nanoparticles to form polymerizable monolayers have emerged as an interesting class of stabilizer ligands for various nanoparticles. High‐surface coverage, their ability to modify the properties of underlying nanoparticles, capability to form polymers of different molecular weights and possibility to make structural modifications make them attractive for their use as stabilizer ligands for nanoparticles. Both in situ and post‐synthesis grafting methods for attaching polymerizable ligands to nanoparticles are frequently used. The advantage of grafting polymerizable stabilizer on the surface of nanoparticles is that initially the polymerizable molecule acts as a proper stabilizer for the nanoparticles and later their surface polymerization or co‐polymerization with another suitable monomer can be carried out to generate the desired polymer scaffold around the nanoparticles, which ensures the increased stability of the resulting core‐polymerized shell nanoparticles. This review discusses interesting reports from recent literature on grafting of polymerizable ligands and their polymerization on gold, silver, silica, and iron oxide nanoparticles.

“…The monofunctionalized NPs were further utilized as artificial molecules, which offers the potential for new versatile applications of the “grafting‐around” concept 23. 24 Recently, we have shown that polymer cages prepared by “grafting‐around” can be used for the size‐selective separation of colloidal AuNPs 25…”

A template synthesis allows the preparation of monodisperse nanoparticles with high reproducibility and independent from self-assembly requirements. Tailor-made polymer cages were used for the preparation of nanoparticles, which were made of cross-linked macromolecules with pendant thiol groups. Gold nanoparticles (AuNPs) were prepared in the polymer cages in situ, by using different amounts of cages versus gold. The polymer cages exhibited a certain capacity, below which the AuNPs could be grown with excellent control over the size and shape. Control experiments with a linear diblock copolymer showed a continuous increase in the AuNP size as the gold feed increased. This completely different behavior regarding the AuNP size evolution was attributed to the flexibility of the polymer chain depending on cross-linking. Moreover, the polymer cages were suitable for the encapsulation of AgNPs, PdNPs, and PtNPs by the in situ method.
