The field of plasmonics is capable of enabling interesting applications in different wavelength ranges, spanning from the ultraviolet up to the infrared. The choice of plasmonic material and how the material is nanostructured has significant implications for ultimate performance of any plasmonic device. Artificially designed nanoporous metals (NPMs) have interesting material properties including large specific surface area, distinctive optical properties, high electrical conductivity, and reduced stiffness, implying their potentials for many applications. This paper reviews the wide range of available nanoporous metals (such as Au, Ag, Cu, Al, Mg, and Pt), mainly focusing on their properties as plasmonic materials. While extensive reports on the use and characterization of NPMs exist, a detailed discussion on their connection with surface plasmons and enhanced spectroscopies as well as photocatalysis is missing. Here, we report on different metals investigated, from the most used nanoporous gold to mixed metal compounds, and discuss each of these plasmonic materials’ suitability for a range of structural design and applications. Finally, we discuss the potentials and limitations of the traditional and alternative plasmonic materials for applications in enhanced spectroscopy and photocatalysis.

“…Modern STEM microscopes can also allow us to identify nanoparticle composition with single-atom resolution, which has helped, for instance, to propose the role of Ag in nanoparticle stabilization. We can also start thinking about merging photon- and electron-based techniques (e.g., cathodoluminescence, PINEM) with purely photon-based (dark-field microscopy) and electron-based (TEM, STEM) techniques to assess the origin, nature, and evolution of plasmonic resonances, which could perhaps be useful at determining how hot electrons can be leveraged to push enzymatic reactions at the nanostar tips . Finally, we should start looking at traditional analytical characterization techniques, such as NMR or XPS, to further integrate our knowledge of gold nanostars beyond shape.…”

It is in fact very important to stress that, when synthesizing materials for biological and clinical applications, it can be even more important to have a complete and detailed knowledge of the nanoparticle's properties, as its interactions with the biological milieu can be complex and often unpredictable.…”

Over the past few years, gold nanostars have gained significant relevance in biology and medicine, in particular, in imaging and photothermal therapy, also owing to their biocompatibility. Furthermore, they have improved the sensitivity of diagnostic assays and have been integrated in lab-on-chip platforms for low-cost, field-deployable devices. However, despite their widespread use, they have not found applicability beyond the research laboratories. One of the main reasons for this limitation has been the almost exclusive focus, until recently, on applications alone and not on the understanding of the fundamental properties of these particles, which has hampered reproducibility, stability, and overall reliability. Recently, however, a resurgence in the fundamental research of gold nanostars has dramatically improved our understanding of their synthesis, functionalization, properties, and thus their applicability. In this Perspective, the literature exploring and improving our knowledge of the physicochemical properties of gold nanostars is critically presented and framed within the specific context of biological and clinical applications. Furthermore, on the basis of the most recently reported results, a path forward is proposed, aimed at enabling an effective integration of these particles in the clinic.

“…In recent years, the use of metallic NPs as an alternative tool for the light regulation of enzymes has gained significant relevance. 16 This arises mainly from the remarkable thermal and optical properties of metallic NPs, through which they offer unique light-stimulus-responsive properties. Upon light irradiation, metallic NPs provide ready heating and cooling rates for biocatalytic processes 17−19 (Figure 1A).…”

Stimuli-Responsive Regulation of Biocatalysis through Metallic Nanoparticle Interaction

et al. 2021

The remote control of biocatalytic processes in an extracellular medium is an exciting idea to deliver innovative solutions in the biocatalysis field. With this purpose, metallic nanoparticles (NPs) are great candidates, as their inherent thermal, electric, magnetic, and plasmonic properties can readily be manipulated upon external stimuli. Exploring the unique NP properties beyond an anchoring platform for enzymes brings up the opportunity to extend the efficiency of biocatalysts and modulate their activity through triggered events. In this review, we discuss a set of external stimuli, such as light, electricity, magnetism, and temperature, as tools for the regulation of nanobiocatalysis, including the challenges and perspectives regarding their use. In addition, we elaborate on the use of combined stimuli that create a more refined framework in terms of a multiresponsive system. Finally, we envision this review might instigate researchers in this field of study with a set of promising opportunities in the near future.
