“…Alternatively, Au‐TiO 2 columnar films were fabricated by depositing gold nanocages on single crystal TiO 2 substrates, which exhibited approximately eight times higher photocurrent than that of the used TiO 2 film under NIR light irradiation. [ 181 ] In Fang's work, AuNR/SnO 2 core–shell nanostructures were obtained by synthesizing SnO 2 shell on AuNRs via hydrolysis of Sn 4+ ions in aqueous ammonia at pH ≈11. [ 182 ] The SPR absorption of the core–shell nanoparticles was controlled in NIR region via optimizing the core size and shell thickness.…”

With the wide utilization of antibiotics, antibiotic‐resistant bacteria have been often developed more frequently to cause potential global catastrophic consequences. Emerging photothermal ablation has been attracting extensive research interest for quick/effective eradication of pathogenic bacteria from contaminated surroundings and infected body. In this field, anisotropic gold nanostructures with tunable size/morphologies have been demonstrated to exhibit their outstanding photothermal performance through strong plasmonic absorption of near‐infrared (NIR) light, efficient light to heat conversion, and easy surface modification for targeting bacteria. To this end, this review first introduces thermal treatment of infectious diseases followed by photothermal therapy via heat generation on NIR‐absorbing gold nanostructures. Then, the usual synthesis and spectral features of diversified gold nanostructures and composites are systematically overviewed with the emphasis on the importance of size, shape, and composition to achieve strong plasmonic absorption in NIR region. Further, the innovated photothermal applications of gold nanostructures are comprehensively demonstrated to combat against bacterial infections, and some constructive suggestions are also discussed to improve photothermal technologies for practical applications.

“…Nanostructured thin films synthesis has attracted enormous interest in the past several decades 39 due to their wide array of applications including solar photovoltaics [2][3][4], solar water-splitting [1,[5][6][7][8][9][10][11], CO 2 photoreduction [12,13], and lithium-ion batteries [14]. Various approaches have 41 been used to synthesize these nanostructured films, such as, thermal oxidation [15], vapor-liquid solid (VLS) growth [16], template-based synthesis [17], electrochemical methods [18] and gas phase methods [1,19,20].…”

“…Three 48 predominant morphologies, namely, dense, columnar, and granular have been reported in the 49 literature [1,2,23]. For applications in solar energy and energy storage, the columnar 50 morphology has proven to be the most advantageous due to its oriented, single crystalline, onedimensional structure, high surface area, and fast electron transfer [1,2,6,14].…”

The aerosol chemical vapor deposition (ACVD) process has been demonstrated as a promising approach to the single step synthesis of nanostructured metal oxide thin films. Multiple process parameters control the nanostructure morphology and the growth of thin films. This work focuses on utilizing a simulation based approach to understand the role of these parameters in governing the morphology of the thin film. A finite element based computational fluid dynamics model, coupled with a discrete-sectional aerosol model, and a boundary layer diffusion and sintering model has been formulated to predict the evolution of particle size distribution and the morphology of the synthesized nanostructured film. The morphology predicted by the model was validated by experimental observations. The model enables scale up and wider application of the ACVD process and can be extended to other gas phase deposition systems.

“…The basic steps in all the gas/vapor phase nanoparticle synthesis are nucleation and condensation of gases and vapor molecules of the precursor, followed by cluster formation and coagulation leading to the formation of primary particles which may further grow into aggregates by sintering, agglomeration and aggregation [72–74]. Various inorganic and organic base nanoparticles including, but not limited to, magnetite, silica, graphene, lipid and titanium dioxide, are used widely as MRI contrast agents, coatings, drug carriers, sensors and coloring agents, as discussed in the previous section, has been reported to be synthesized by flame [75–79], furnace [80], aerosol chemical vapor deposition [81, 82] and electrospray [17, 20, 83, 84]. A typical process of aerosol based nanoparticles and nanostructure synthesis of nanoparticle can be seen in Figure 2.…”

This review gives a short overview on the widespread use of nanostructured and nanocomposite materials for disease diagnostics, drug delivery, imaging and biomedical sensing applications. Nanoparticle interaction with a biological matrix/entity is greatly influenced by its morphology, crystal phase, surface chemistry, functionalization, physicochemical and electronic properties of the particle. Various nanoparticle synthesis routes, characteristization, and functionalization methodologies to be used for biomedical applications ranging from drug delivery to molecular probing of underlying mechanisms and concepts are described with several examples (150 references).
