“…In contrast to the former two grafting techniques, the " grafting from " approach leads to polymer brushes with high grafting densities, which infl uence the chemical and physical properties of the nanoparticles, especially the wettability properties. Several reports were published where various kinds of polymers such as poly(ethylene glycol) [132,133] , poly(styrene) [134,135] , poly(methacrylamides) [136,137] , poly(methacrylates), [123] poly(vinylpyridines) [129] are tethered by one end to gold nanoparticles by either " grafting to " [122,138] , the in-situ " grafting to " [12] or the " grafting from " [128] technique [82] .…”

An essential element in the synthesis of nanomaterials based on gold nanoparticles comprises the control over parameters such as size, shape and composition, due to their strong infl uence on the properties of the particles. However, it is the coating material which often plays the primary role in tuning the size, morphology, and even plasmon resonance wavelength or mode multiplicity, as well as colloidal stability and functional versatility, ultimately determining the physical, chemical, optical, electronic and catalytic properties of the nanoparticles. Therefore, it is utterly important to select the adequate wet chemistry synthetic approach with the most suitable coating material for the preparation of gold nanoparticles with the desired requirements. Within this context, this review is focused on describing various types of organic and inorganic coating materials for gold nanoparticles that may notably affect their optical properties by either directly infl uencing the synthesis procedure or by changing their chemical and physical properties upon post-synthetic modifi cations, such that they exhibit novel and useful optical properties.

“…Polymers terminated with a sulfur containing group (dithioester, trithioester, thiol, thioether and disulfide) provide chemical-bonded shell layers around the gold cores, which also occurs in the "grafting from" method. 29,30 The polymers terminated with sulfur containing groups can be synthesized by a radical polymerization using chain transfer reagents containing sulfur atoms. 31 The evolution of gold cores in aggregates composed of conventional polymers without sulfur atoms results in gold nanocomposites in which the polymers interact with gold cores through multi-point physical adsorption.…”

In this brief review, gold nanoparticles conjugated with functional polymers are described from the viewpoint of application to sensing materials. The optical properties of gold nanoparticles, the synthesis of polymer-functionalized gold nanoparticles, and their analytical applications are discussed. Polymer-functionalized gold nanoparticles are categorized into two classes: biopolymer-conjugated gold nanoparticles and artificial-polymer conjugated gold nanoparticles. Fluorometric and colorimetric sensing using gold nanoparticles are focused; fluorometric detection enables us to exploit sensitive assays for practical use. Furthermore, chemical amplification using gold nanoparticles is also discussed for the sensitive probing.
