“…These DNA-based experiments can further explore molecule-based electronics and new biosensing platforms, because the DNA strand provides a versatile platform for interactions between ions, proteins, and other molecules within the photo-assisted transport junction. [12,119,156] As previously described, the plasmon resonance wavelength is affected by the gap conductance, molecule size, local refractive index, and charge transfer behavior within junctions. However, one study, published in 2019 by Readman et al, suggested the opposite plasmon resonance behavior to that previously found; [157] they identified anomalously large spectral shifts with subatomic resolution, using a lanthanide (Ln = Sm, Tb, Er, Lu) ion with two conjugated phthalocyanine (Pc) molecules.…”

scanning tunneling microscopy (STM), [5,6] atomic force microscopy (AFM), [7] and other techniques allowing resolution to be reduced to the atomic scale can help realize atomic-scale world exploration. This is the starting point of the nanotechnology era; since its inception, this technology has changed the nature of almost every human-made object. Six decades after Richard Feynman's lecture, we find that there is still plenty of room at the bottom, through the incorporation of nanophotonics. [8] To elucidate: quantum plasmonics has emerged as an attractive research field in new nanophotonics; research is underway to reveal and accurately describe the quantum nature of electrons at the bottom of extremely confined nano-or sub-nanometer scale materials, using light. [9,10] By exploring the quantum mechanical interactions of matter with light (in particular, using the coherent interactions between the plasmonic cavity and the material), [11][12][13][14][15][16][17][18] these efforts seek to establish new frontiers in information processing technology and to satisfy the everincreasing requirements for speed and capacity in quantum computing, quantum cryptography, and quantum metrology. They might also suggest research fields beyond this, involving the ultimate miniaturization of photonic components and the extreme limits of the light-matter interaction. These advantages may help solve some fundamental problems of electronics, such as those of bandwidth, frequency, and energy consumption. [19] In this review, we describe recent developments in the research of exotic materials capable of mediating quantum plasmonics and inducing quantum energy transport. We briefly provide classical and quantum descriptions of matter, from the bulk, nano, and cluster scales down to atomic matter, exploring the band structures via their optical responses. By considering a single nanoplasmonic material, we describe the theoretical and experimental findings pertaining to assembled nanoplasmonic structures, in the context of the plasmonic gap distance and the type of advanced functional material. The plasmonic gap herein refers to a nanometer or sub-nanometer gap that transports (couples, tunnels, exchanges, confines) electromagnetic energy between plasmonic resonators. Advanced functional materials within an extremely confined metallic resonator are described; these include air/vacuum, aliphatic and conjugated molecules, 2D materials, organic and inorganic materials with At the interfaces of metal and dielectric materials, strong light-matter interactions excite surface plasmons; this allows electromagnetic field confinement and enhancement on the sub-wavelength scale. Such phenomena have attracted considerable interest in the field of exotic material-based nanophotonic research, with potential applications including nonlinear spectroscopies, information processing, single-molecule sensing, organic-molecule devices, and plasmon chemistry. These innovative plasmonics-based technologies can meet the ever-increasing demands for speed and ca...

“…Nevertheless, there remains much to learn about these systems using, for example, in situ characterization, precise control, mass production, mechanism exploration, and functional application of noble‐metal composites. On the other hand, the versatile design of noble‐metal composites allows them to be used in other interesting emerging fields, covering electromagnetic interference (EMI) shielding, [ 285–287 ] printing, [ 288–291 ] biotechnology, [ 292–294 ] sensors, [ 295–298 ] and solar energy. [ 299–301 ] Based on the unique features of noble‐metal composites, combined with their finely tuned component and structure design, noble‐metal composites can be produced at low cost and in batches, which further promotes their application in the fields of optics, catalysis, medicine, and electricity.…”

Great effort has recently been made to develop noble‐metal nanomaterials with good activity, high durability, and appropriate selectivity to improve their efficiency in functional applications, while maintaining low cost. The use of noble metals not only makes the last requirement hard to meet but also restricts stability at high temperatures and limits mass production. Recently, some promising strategies, such as optimizing the components and fine‐tuning the structure, have been explored, which promise to enable the fabrication of unique noble‐metal nanostructures with lower loading and higher stability. Herein, recent achievements in manufacturing noble‐metal composites are reviewed, particularly focusing on unique and key factors in rational design and control of structure and components. Two applications of noble‐metal composites in optical and catalytic applications are focused on to illustrate their rational synthesis and design. In addition, current challenges and prospects for future development in this rapidly blossoming field are discussed.
