“…As seen in several examples, weak couplings can control the emission strengths of excitons. [205][206][207][208] On the other hand, when g > γ QE and κ, strong coupling occurs; thus, a coherent energy exchange between the two quantum states (e.g., plasmons and excitons) occurs before they are radiated to free space or damped; this produces a hybridized channel. [209][210][211] This coherent oscillation of the hybridized states splits the emission peak into two and corresponds to the hybrid plasmon-exciton state known as a plexciton, in a process referred to as Rabi splitting.…”

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...

“…However, it worth noting that even a small amount of γ -peptide (in average seven γ-peptide sequences per hybrid-structure) is able to promote the uptake of nanohybrids, which hydrodynamic size exceeds both the QD construct of our previous study (d(QD-LA)~10-15 nm) 20 as well as the virus itself (d~40 nm). 19 Due to their bimodal character and sensitive exciton-plasmon coupling 29…”

“…Water-soluble carbon nanotubes are being investigated for gene and drug delivery due to their nontoxicity, ease in crossing biological barriers and ability to transport molecules to the cytoplasm [160]. Moreover, the association of the dual plasmonic agents in such a hybrid construct demonstrates the enhanced physicochemical properties of both agents and shows outstanding functionality by combining the effects of two different nanostructures [161,162].…”

Skin cancer is a high burden disease with a high impact on global health. Conventional therapies have several drawbacks; thus, the development of effective therapies is required. In this context, nanotechnology approaches are an attractive strategy for cancer therapy because they enable the efficient delivery of drugs and other bioactive molecules to target tissues with low toxic effects. In this review, nanotechnological tools for skin cancer will be summarized and discussed. First, pathology and conventional therapies will be presented, followed by the challenges of skin cancer therapy. Then, the main features of developing efficient nanosystems will be discussed, and next, the most commonly used nanoparticles (NPs) described in the literature for skin cancer therapy will be presented. Subsequently, the use of NPs to deliver chemotherapeutics, immune and vaccine molecules and nucleic acids will be reviewed and discussed as will the combination of physical methods and NPs. Finally, multifunctional delivery systems to codeliver anticancer therapeutic agents containing or not surface functionalization will be summarized.
