“…Concerning applications, SERS has been used for the detection of food additives or contaminants [54,55,56,57], explosives and warfare agents [58], biological species [59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76], in forensic science [77], and to monitor reactions catalyzed by metallic surfaces [78] or nanoparticles [79]. General overviews on SERS can be found in books [6,8,80,81,82,83,84], Faraday discussions [85,86,87,88,89], special issues [90,91,92,93], and reviews [7,9,36,76,94,95,96,97,98]. Finally, it is worth mentioning that the plasmonic amplification of the optical response has been exploited to enhance also coherent anti-Stokes Raman scattering (CARS) [99,100], stimulated Raman scattering (SRS) [101,102], hyper Raman scattering (HRS) [75,103,104,…”

A Review on Surface-Enhanced Raman Scattering

Surface-enhanced Raman scattering (SERS) has become a powerful tool in chemical, material and life sciences, owing to its intrinsic features (i.e., fingerprint recognition capabilities and high sensitivity) and to the technological advancements that have lowered the cost of the instruments and improved their sensitivity and user-friendliness. We provide an overview of the most significant aspects of SERS. First, the phenomena at the basis of the SERS amplification are described. Then, the measurement of the enhancement and the key factors that determine it (the materials, the hot spots, and the analyte-surface distance) are discussed. A section is dedicated to the analysis of the relevant factors for the choice of the excitation wavelength in a SERS experiment. Several types of substrates and fabrication methods are illustrated, along with some examples of the coupling of SERS with separation and capturing techniques. Finally, a representative selection of applications in the biomedical field, with direct and indirect protocols, is provided. We intentionally avoided using a highly technical language and, whenever possible, intuitive explanations of the involved phenomena are provided, in order to make this review suitable to scientists with different degrees of specialization in this field.

“…1 Raman spectroscopy, which probes vibrational transitions, allows the label-free identification of a wide variety of molecules, thereby becoming a highly relevant tool in disciplines including biology, medicine, or forensics. [2][3][4] However, the extremely low cross section of Raman scattering usually requires either large amounts of analyte or very powerful laser sources, which can in turn degrade the molecules. 5 Surface-enhanced Raman scattering (SERS) has mitigated this issue, on the basis of the amplification of the Raman signal of molecules in contact with nanostructured metallic surfaces.…”

Metal colloids are of great interest in the field of nanophotonics, mainly due to their morphology-dependent optical properties, but also because they are high-quality building blocks for complex plasmonic architectures. Close-packed colloidal supercrystals not only serve for investigating the rich plasmonic resonances arising in strongly coupled arrangements but also enable tailoring the optical response, on both the nano- and the macroscale. Bridging these vastly different length scales at reasonable fabrication costs has remained fundamentally challenging, but is essential for applications in sensing, photovoltaics or optoelectronics, among other fields. We present here a scalable approach to engineer plasmonic supercrystal arrays, based on the template-assisted assembly of gold nanospheres with topographically patterned polydimethylsiloxane molds. Regular square arrays of hexagonally packed supercrystals were achieved, reaching periodicities down to 400 nm and feature sizes around 200 nm, over areas up to 0.5 cm. These two-dimensional supercrystals exhibit well-defined collective plasmon modes that can be tuned from the visible through the near-infrared by simple variation of the lattice parameter. We present electromagnetic modeling of the physical origin of the underlying hybrid modes and demonstrate the application of superlattice arrays as surface-enhanced Raman scattering (SERS) spectroscopy substrates which can be tailored for a specific probe laser. We therefore investigated the influence of the lattice parameter, local degree of order, and cluster architecture to identify the optimal configuration for highly efficient SERS of a nonresonant Raman probe with 785 nm excitation.

“…Also, AgNS has strong NIR absorption, which is useful for PA imaging. Additionally, AgNS do not induce any in vivo toxicity, as confirmed by cytotoxicity tests (Baumberg et al, 2017). Cha et al (2017) demonstrated dual-modal detection of sentinel lymph nodes (SLNs) using a silica-coated silver bumpy nanoshell probe (AgNS@SiO 2 ): imaging the SLN with a PA signal and in vivo multiplex identification of targets in the located region with SERS.…”

Non-invasive tracking for monitoring the selective delivery and transplantation of biotargeted agents in vivo has been employed as one of the most effective tools in the field of nanomedicine. Different nanoprobes have been developed and applied to bioimaging tissues and the treatment of diseases ranging from inflammatory and cardiovascular diseases to cancer. Herein, we will review the recent advances in the development of optics-responsive nanomaterials, including organic and inorganic nanoparticles, for multimodal bioimaging and targeted therapy. The main focus is placed on nanoprobe fabrication, mechanistic illustrations, and diagnostic, or therapeutical applications. These nanomedicine strategies have promoted a better understanding of the biological events underlying diverse disease etiologies, thereby facilitating diagnosis, illness evaluation, therapeutic effect, and drug discovery.
