“…Next, we describe some examples of anisotropic growth in situ, including those that use patterning ( i.e. , BCML), ,, nonpatterned in situ growth, , and in situ overgrowth on seeds prepared from colloidal solution. ,, Thus far, examples of shapes accessible with in situ shape control include spheres of different sizes, , polyhedra/triangular plates, ,,, branched structures, ,,,, nanorods, ,,,, concave structures, and standing nanowires , (some examples are highlighted in Table ). In the next sections, we discuss selected work focused on the syntheses of various anisotropic structures in situ , beginning with nanorods, then continuing to platelets, stars, and nanowires.…”

Plasmonic gold nanoparticles have been used increasingly in solid-state systems because of their applicability in fabricating novel sensors, heterogeneous catalysts, metamaterials, and thermoplasmonic substrates. While bottom-up colloidal syntheses take advantage of the chemical environment to control size, shape, composition, surface chemistry, and crystallography of the nanostructures precisely, it can be challenging to assemble nanoparticles rationally from suspension onto solid supports or within devices. In this Review, we discuss a powerful recent synthetic methodology, bottom-up in situ substrate growth, which circumvents time-consuming batch presynthesis, ligand exchange, and selfassembly steps by applying wet-chemical synthesis to form morphologically controlled nanostructures on supporting materials. First, we briefly introduce the properties of plasmonic nanostructures. Then we comprehensively summarize recent work that adds to the synthetic understanding of in situ geometrical and spatial control (patterning). Next, we briefly discuss applications of plasmonic hybrid materials prepared by in situ growth. Overall, despite the vast potential advantages of in situ growth, the mechanistic understanding of these methodologies remains far from established, providing opportunities and challenges for future research.

“…89 In general, capping ligands are divided into five categories: polymeric ligands, ionic organic ligands, nonionic organic ligands, small molecules, and inorganic ions. Popular polymer ligands include PVP, 90,91 polyoxyethylene (100) stearyl ether (Brij 700), 92 polyethylenimine, 93 polyamine, 94 etc. They have long carbon chains that can prevent particles from coalescing.…”

This paper reviews recent studies on the preparation of two-dimensional (2D) metal nanostructures, particularly nanosheets. As metal often exists in the high-symmetry crystal phase, such as face centered cubic structures, reducing the symmetry is often needed for the formation of low-dimensional nanostructures. Recent advances in characterization and theory allow for a deeper understanding of the formation of 2D nanostructures. This Review firstly describes the relevant theoretical framework to help the experimentalists understand chemical driving forces for the synthesis of 2D metal nanostructures, followed by examples on the shape control of different metals. Recent applications of 2D metal nanostructures, including catalysis, bioimaging, plasmonics, and sensing, are discussed. We end the Review with a summary and outlook of the challenges and opportunities in the design, synthesis, and application of 2D metal nanostructures.

“…Recently, Neretina and co-workers have adopted a plasmon-mediated synthetic approach for the nanofabrication of periodic arrays of heteroepitaxially aligned Au nanoplates for the first time. [145,146] The uniqueness of the approach lied in the successful integration of wafer-based technologies with colloidal chemistry. Substrate-based Au seeds lined with stacking faults-prepared via the combination of nanoimprint lithography and vapor phase assembly processes-were used for the plasmon mediated chemistry to yield organized Au nanoplates over a large area (Figure 9c,d).…”
