“…Preferably, the LSPR signal of the NPs should be located in the spectral range in which the electromagnetic wave has maximal ability to penetrate the irradiated tissue (known as the "biological optical window") for theranostic applications. The modification of the plasmonic absorption properties can be obtained by control of the spatial parameters (i.e., size, shape, and structure) of the NPs [9]. Indeed, plasmonic MeNPs have been explored for treating cancer by photothermal ablation therapy.…”

“…Indeed, plasmonic MeNPs have been explored for treating cancer by photothermal ablation therapy. This approach is based on the nanoparticles' heat generation from light for destroying cancer cells, and requires high optical absorption and strong photothermal conversion efficiency [8,9]. Gold nanoparticles (AuNPs) are by far the most studied nanomaterials (NMs) regarding their biomedical application.…”

Recent advances in the synthesis of metal nanoparticles (MeNPs), and more specifically gold nanoparticles (AuNPs), have led to tremendous expansion of their potential applications in different fields, ranging from healthcare research to microelectronics and food packaging. The properties of functionalised MeNPs can be fine-tuned depending on their final application, and subsequently, these properties can strongly modulate their biological effects. In this review, we will firstly focus on the impact of MeNP characteristics (particularly of gold nanoparticles, AuNPs) such as shape, size, and aggregation on their biological activities. Moreover, we will detail different in vitro and in vivo assays to be performed when cytotoxicity and biocompatibility must be assessed. Due to the complex nature of nanomaterials, conflicting studies have led to different views on their safety, and it is clear that the definition of a standard biosafety label for AuNPs is difficult. In fact, AuNPs’ biocompatibility is strongly affected by the nanoparticles’ intrinsic characteristics, biological target, and methodology employed to evaluate their toxicity. In the last part of this review, the current legislation and requirements established by regulatory authorities, defining the main guidelines and standards to characterise new nanomaterials, will also be discussed, as this aspect has not been reviewed recently. It is clear that the lack of well-established safety regulations based on reliable, robust, and universal methodologies has hampered the development of MeNP applications in the healthcare field. Henceforth, the international community must make an effort to adopt specific and standard protocols for characterisation of these products.

“…Regarding to antibacterial properties of Ag‐NPs, even though the mechanism is not fully elucidated and, a number of authors propose diverse pathways, there is an agreement on their specific toxicity [5] and, that antibacterial skills are associated with prism‐shaped nanoplates and the presence of {111} facets [6] . This feature, in turn, seems to also be a condition for nanosilver's precise near infrared localized surface resonance plasmon (NIR‐LSRP) excitations [1d,7] . Considering potential of Ag‐NPs to be exploited in novel theranostic medical therapies and the physicochemical characteristics that are necessary to induce the desired functionalities, in this work, we present an automated single‐phase flow‐batch system to create custom silver {111}‐faceted prism‐like nanoplates.…”

Traditionally, silver nanoparticles exhibiting anisotropic prism‐shape are synthetized by bulk wet chemical reduction systems [6,7b] with the approach of one‐pot stirring, shaking or additional settings as gas‐, [8] pH‐, [7a] microwave‐ [9] and light‐assistance [1d,10] . Despite progress in the field, due to subtle reaction of mass transfer kinetics that dictates defect formation, tuning the structure of {111}‐faceted prism‐like Ag‐NPs is challenging [7a] .…”

Silver nanoparticles (Ag‐NPs) exhibit the highest efficiency of localized surface plasmon resonance (LSPR) excitation that can be tuned to any wave length in the visible spectrum. Its performance depends to a large extent on its physicochemical characteristics such as size and shape; which, in turn, can be modulated by the selective growth of their crystalline facets. We used a simple direct chemical reduction method with a precise manipulation of seed‐mediated growth control through an automated single‐phase continuous flow‐batch system to induce customized geometries on Ag‐NPs. Optimization of the experimental design was carried out from a multivariate analysis, where the height / width ratio of LSPR band was used as response signal. Proposed methodology controls the critical steps in the synthesis of Ag‐NPs that modulate their morphology to attain customized surface plasmon resonance in an interval of 380 nm (spherical‐shaped nanoparticles) to 925 nm ({111}‐ faceted prism‐shaped nanoplates) absorptions, leading to a versatile platform to extend their potential applications. Although the present work focused on silver nanoparticles, we believe that this methodology can be extended to any free‐electron metals.

“…Evaluation of how the laser-assisted wet chemical treatment of Ag nanoparticles affects their spatial parameter-shaping localized surface plasmon resonance has also been presented (see Ref. [34]). Furthermore, a resonance of surface-localized plasmons in a system of periodically arranged gold or silver nanowires on a dielectric substrate has been studied [35].…”

Gold-nanorod arrays of a quasi-hexagonal shape are successfully obtained with electrochemical deposition method and their optical properties are investigated. The optical response of a two-layer structure, in which the first layer is a nanocomposite consisting of Au nanorods and the second one is a thin indium tin oxide film on a glass substrate, has been analyzed. Dependences of absorption crosssection of Au nanorods on the light wavelength at different eccentricities are modelled using electrostatic approximation. It is shown that longitudinal plasmon resonance prevails over other resonances for the Au nanorods deposited on glass substrates. A Maxwell−Garnett theory and a matrix method are used to predict the optical characteristics of the whole structure. We have demonstrated that it is possible to estimate the concentration of nanorods on the surface using the appropriate simulation results. In addition, efficient absorption properties can be obtained at a given wavelength by changing the geometry of nanorods. In particular, there is a shift of the absorption peak towards near-infrared region whenever the nanorods become high enough and smaller in diameter.
